Hyper-v 2012 r2 slow throughputs on network / live migrations

Hi, maybe someone can point me in the right direction, I have 10 servers 5 Dell r210s and 5 Dell R320's, I have basically converted these servers to standalone hyper-v 2012 servers, so there is no clustering on any at the moment.
Each server is configured with 2 1Gb nics teamed via a virtual switch, now when I copt files between server 1 and 2 for example I see 100MBs throughput, but if I copy a file to server 3 at the same time the file copy load splits the 100MBs throughput between
the 2 copy processes. I was under the impression if I copied 2 files to 2 totally different servers the load would basically be split across the 2 nics effectively giving me 2Gbs throughput but this does not seem to be the case. I have played around with tcpip
large send offloads, jumbo packets, disabled vmq on the cards, they are broadcoms. :-( but it doesn't really seem to make a difference with all of these settings.
The other issue is If I live migrate a 12Gb vm machine running only 2gb ram, effectively just an o/s it takes between 15 to 20 minutes to migrate, I have played around with the advanced settings, smb, compression, tcpip not real game changers, BUT if I shut
town the vm and migrate it, it takes, just under 3 and a half minutes to move across.
I am really stumped here, I am busy in a test phase of hyper-v but cant find any definitive documents relating to this stuff.

Hi Mark,
The servers (hyper-v 2012 r2) are all basically configured with ssvmm2012R2 where they all have teamed 1Gb pNics, into a virtual switch, then there are vNics for the Vmcloud, live migration etc. The physical network is 2 Netgear Gs724T switches which
are interlinked and each servers 1st nic is plugged into the switch1 and the second nic is plugged into the switch2.See Below Image) The hyper-v port is set to independent Hyper-v load balancing.
The R320 servers are running raid 5 sas drives, the R210s have 1Tb drives mirrored. The servers all are using DAS storage, we have not moved to looking at using iscsi and san is out the question at the moment.
I am currently testing between 2x 320s and 2x R210s, I am not copying data to the vm's yets, I am basically testing the transfer between the actual hosts at the moment by copying a 4Gb file manually, After testing the live migrations I decided to test to
see the transfer rates between the servers first, I have been playing around with the offload settings and rss, what I don't understand is yesterday, the copy between the servers was running up to 228Mbs ie (using both nics) when copying
the file between the servers, and then a few hours later it only was copying at 50/60Mbs, but its now back at 113Mbs seemingly to be only using one nic.
I was under the impression if you copy a file between 2 servers the nicks could use the 2gb bandwidth, but after reading many posts they say only one nic, so how did the copies get up to 2Gb yesterday. Then again if you copy files between 3 servers, then
each copy would use one nic, basically giving you 2Gbs, but this is again not being seen.

VM windows 2008 Cluster on Hyperv 2012 Server FC Disk error after Live Migration of the active VM Cluster Node

Deployed a 2 nodes Windows 2008 R2 SP1 Failover Cluster on a HyperV 2012 Server cluster deployed on IBM HS23 blade.
Disk susbsystem is IBM Storwize V7000. MPIO driver installed plus IBM DDSM.
Lun presented to the VM are connected with Virtual FC Adapter and everything works fine in the cluster until we start a live migration of the VM which hold the cluster disks online.
After migration complete positively, at the moment the MPIO of the migrated VM goes crazy with a lot of errors (source: mpio eventID 16 ) and warnings (source: mpio EventID: 17) in the system event log. After that the disks becomes unavailable.
Consequently everything hangs until power off the migrated vm, so the services on the cluster switchs on the second node.
I try to set the registry key HKLM\CurrentControlSet\Services\Disk\TimeOutValue to 190 as i found on various articles but nothing seems to change....
Any idea?

Hello,
I've just been through the IBM interoperability matrix and came across this statement:
Hyper-V on x64 based systems is supported with the following guest OS: Windows 2003 32bit, Windows 2003 64bit, Windows 2008 32bit, Windows 2008 64bit.
Clustering of guest OS is not supported at this time. When using Emulex HBAs with Hyper-V please select the settings mentioned in the Host Attachment section of SVC Info Center

How Can we force the Hyper-V Replica to use a dedicated network between two hyper-v hosts?

Dear Team,
How can we force Hyper-V Replica to use a dedicated network between two hyper-v hosts?
For live migration, we can choose the desired network in Hyper-V Manager (Use these IP addresses for Live Migration).
I have two 10G adapters teamed together, the virtual switch is created on top as converged network with several vNICs (MangementOS, LiveMigratrion, Backup, etc...)
Each network is set with a specific VLAN to isolate the traffic.
The two Hyper-V hosts are on the same LAN and domain.
Thank you.
Regards,

I have accomplished this by using a DNS pointer specifying an IP address on that dedicated network. That will force traffic done that network.

Hyper V 2012 VM stopping state

I have an issue with a VM that enters the stopping state. This happens every time a scheduled reboot occurs after applying windows updates. The VM was P2V using SCVMM 2012 SP1. The hosts are running Hyper-V 2012. The VM is W2008 R2.
I am unable to kill the VMWP.exe process, error: 'access denied'
I cannot move any other VMs to other host, error: 'resource locked status'
The only workaround I have found is to power cycle the host which forces the VMs to live migrate onto other hosts. This also brings up the problem VM and releases from stopping state.
I have applied hotfix KB2823643 (http://support.microsoft.com/kb/2823643) but no change.
This is happening when the VM is on all hosts.
Any ideas why?
Craig Brand

Try this hotfix also -
http://support.microsoft.com/kb/2848344
There is a case with the similar error message but with a different symptom. I'm advised to look at the vssadmin writers to verify if at the time of the reboot I have an
issue. Related article below.

Sadly I haven't had to apply any major updates so hard to replicate this. Next reboot scheduled Monday so maybe an update then :s

Hyper-v and very slow network

Dear all,
I have a big problem with my hyper-v server and network card. I've found a lot of topic around this question but none of them helped me.
I have a Win 2008 R2 Server with only Hyper-V installed. I have 3 NIC , one is reserved to the host management and the others two are reserved for virtual machine .
All NIC are Intel, one is integrated on the Intel motherboard and the others are Intel Gigabit ET Dual port .
Before installing the role of Hyper-V all NIC worked perfectly with speed around 1Gb (file transfer average 90 MB/Sec, of course I have a Gigabit LAN) .
After Hyper-V install, the host system is going very slow and the network file transfer using the dedicated NIC is about ten time slower (9-10MB /sec) . Same problem with all VM off and also if I remove all VM !
I tried all of suggestion found in old post (disabling TCP checksum / offload ...) but nothing happens.
What is really strange is that by removing all network card all the Host operating system seems to improve the speed... but, of course, I can't use my LAN :(
I need help because every night I must make a full backup of Virtual hard disk from the host to a backup server in my lan.
My configuration:
- Server Win 2008 R2 SP1 with Hyper-V and no others role
- 2 Virtual Machine (one Win 2008 R2 and one Win 7 Ultimate)
- NAS Linux (access via SMB with no problem)
- Various Windows 7 Pro client
Thanks in advance to everybody,
Luca M.

I disabled the VMQ on the configuration of the HV physical machine, a LACP with 2 NICs, so i disabled on both.
Before, i tried to disable VMQ on the Multiplex adapter (connected to the vswitch and dind´t worked
The ping times drop form 200ms to 6ms, normal in my environment

Hyper-V 2012 R2 does not disable the protocols on the physical network adapter

Hello,
I have a problem with the creation of an external network in Hyper-V (2012 r2), when I create the external network does not want to share with the host, therefore I take the check to share it. Hyper-V on the network adapter "real" does not disable
all protocols, but active all inclusive TCP4 and 6.
How so?
I have 2 other servers with the same configuration and run regularly.
Thanks in advance

Hi Fabio,
"when I create the external network does not want to share with the host, therefore I take the check to share it. "
Based on my understanding ,after creating a external Vswitch the physical NIC will only have protocol "hyper-v external virtual switch " whatever we check "allow management operation...." or not .
Do you mean after you create the external Vswitch , the physical adapter still have another protocol ?
If yes , my suggestion is to remove the physical NIC from "device manager " , then restart server and reload the driver then create the external Vswitch again .

Hyper V 2012 network options

We are testing Hyper V 2012, and the networking options seem confusing.
I created a virtual external switch on the host, trunked vlans down to it from an upstream 3750, and created some VMs.
No problem there: the VMs were able to get outside, etc.
But what do the "private" and "internal" networks give me?
It is my understanding that neither private nor internal networks can communicate with subnets/networks outside the host(s)
I thought maybe I could use private networks and have the Hyper V 2012 host route the traffic out to the real world, apply security policies, etc.
Is this even possible? Or do the options simply isolate VMs? (and are therefore not any better of existing VMWare technology)

My understanding is that the private and internal networks are for networking specific to the hyper-v host. So you can create a private netwok that allows two VMs to communicate with each other but not the outside world.
There is no way to forward that traffic outside the hyper-v host.
We are working on N1KV for Hyper-v which will bring most of the NXOS feature set to Hyper-v. So PVLANs, ACLs, port-channels, QOS, etc...

SRP 541W VERY slow throughput

Hi!
I have had my SRP 541w for just over a year, BUGGER! So it is out of warranty now. Bought it in September 2012. It has been working like a charm since then. A couple of days ago my network speed suddenly dropped to about 10 mbit/s. That is true of all connections LANtoLAN, WANtoLAN and LANtoWAN. All my equipment is 1 gb/s. I have upgraded the firmware to 1.2.6, set the speed of the LAN ports to 1000 FULL, rebooted, tried with only one computer attached nothing else connected. WAN disconnected and throughput between LAN ports, nothing seems to make any difference. Did a factory reset, still no change.
I would really appreciate help on this! I really hope it has not stopped working properly. Not good advertisment for CISCO in that case, One month over warranty and suddenly BANG.
Any ideas?
Regards,
Sven Gustavsson

Got my hands on a multi adatper and plugged that in as well. No change, powerlight flashes and extremly slow throughput.
If it is of any use, the power light flashes 3 times then a few seconds delay, then flashes 3 times then few seconds delay and repeat. This does seem lik an error code of some kind that we have no documentation for. Maybe its time for someone from Cisco to enlighten us as to the nature of the powerlight flashing?

Win 2012 shared-nothing live migration slow performance

Win 2012 shared-nothing live migration slow performance
Hello,
i have two standalone hyper-v servers - A) 2012 and B) 2012 r2.
I tried live migration on non-shared storage between them. The functionality is alright but performance is low. The copying take a long time with max 200 Mbps.
I am not able to find the bottleneck. Network a disk performance seems to be good. It is 1Gbps network and when I tried simple copy paste the vhd file from A to B through cifs protocol, the speed was about almost full 1Gbps - it was nice and fast.
Is it feature? I am not able reach full network performance with shared-nothing live migration.
Thank you for reply
sincerely
Peter Weiss

Hi,
I don’t found the similar issue with Hyper-V, Does both of your hosts have the chipsets in the same family? Could you try to switch the three Live Migration Performance
Option method then monitor again? Or It seems there may have some disk or file system performance issue, please try to update your RAID card firmware to the least version.

Windows 2012 Nodes - Slow CSV Performance - Need help to resolve my iSCSI issue configuration

I spent weeks going over the forums and the net for any publications and advice on how to optimize iSCSI connections and i'm about to give up. I really need some help in determining if its something i'm not configuring right or maybe its an equipment
issue.
Hardware:
2x Windows 2012 Hosts with 10 Nics (same NIC configuration) in a Failover Cluster sharing a CSV LUN.
3x NICs Teamed for Host/Live Migration (192.168.0.x)
2x NICS teamed for Hyper-V Switch 1 (192.168.0.x)
1x NIC teamed for Hyper-V Switch 2 (192.168.10.x)
4x NICs for iSCSI traffic (192.168.0.x, 192.168.10.x, 192.168.20.x 192.168.30.x)
Jumbo frames and flow control turned on all the NICs on the host. IpV6 disabled. Client for Microsoft Network, File/Printing Sharing Disabled on iSCSI NICs.
MPIO Least Queue selected. Round Robin gives me an error message saying "The parameter is incorrect. The round robin policy attempts to evenly distribute incoming requests to all processing paths. "
Netgear ReadyNas 3200
4x NICs for iSCSI traffic ((192.168.0.x, 192.168.10.x, 192.168.20.x 192.168.30.x)
Network Hardware:
Cisco 2960S managed switch - Flow control on, Spanning Tree on, Jumbo Frames at 9k - this is for the .0 subnet
Netgear unmanaged switch - Flow control on, Jumbo Frames at 9k - this is for .10 subnet
Netgear unmanaged switch - Flow control on, Jumbo Frames at 9k - this is for .20 subnet
Netgear unmanaged switch - Flow control on, Jumbo Frames at 9k - this is for .30 subnet
Host Configuration (things I tried turning on and off):
Autotuning
RSS
Chimney Offload
I have 8 VMs stored in the CSV. When try to load all 8 up at the same time, they bog down.  Each VM loads very slowly and when they eventually come up, most of the important services did not start. I have to load
them up 1 or 2 at a time. Even then the performance is nothing like if they were loading up on the Host itself (VHD stored on the host's hdd). This is what prompted me to add in more iSCSI connections to see if I can improve the VM's
performance.  Even with 4 iSCSI connections, I feel nothing has changed. The VMs still start up slowly and services do not load right. If I distribute the load with 4 VMs on Host 1 and 4 VMs on Host 2, the load up
times do not change.
As a manual test for file copy speed, I moved the cluster resources to Host 1 and copied a VM from the CSV and onto the Host.   The speed would start out around 250megs/sec and then eventually drop down to about 50/60 megs/sec. If I turn
off all iSCSI connections except one, it get the same speed. I can verify from the Windows Performance Tab under Task Manager that all the NICS are distributing traffic evenly, but something is just limiting the flow. Like what I stated on top,
I played around with autotuning, RSS and chimney offload and none of it makes a difference.
The VMs have been converted to VHDx and to fixed size. That did not help.
Is there something I'm not doing right? I am working with Netgear support and they are puzzled as well. The ReadyNas device should easily be able to handle it.
Please help! I pulled my hair out over this for the past two months and I'm about to give up and just ditch clustering all together and just run the VMs off the hosts themselves.
George

A few things...
For starters, I recommend opening a case with Microsoft support. They will be able to dig in and help you...
Turn on the CSV Cache, it will boost your performance
http://blogs.msdn.com/b/clustering/archive/2012/03/22/10286676.aspx
A file copy has no resemblance of the unbuffered I/O a VM does... so don't use that as a comparison, as you are comparing apples to oranges.
Do you see any I/O performance difference between the coordinator node and the non-coordinator nodes? Basically, see which node owns the cluster Physical Disk resource... measure the performance. Then move the Physical Disk resource for the
CSV volume to another node, and repeat the same measure of performance... then compare them.
Your IP addressing seems odd... you show multiple networks on 192.168.0.x and also on 192.168.10.x.   Remember that clustering only recognizes and uses 1 logical interface per IP subnet. I would triple check all your IP schemes...
to ensure they are all different logical networks.
Check you binding order
Make sure you NIC drivers and NIC firmware are updated
Make sure you don't have IPsec enabled, that will significantly impact your network performance
For the iSCSI Software Initiator, when you did your connection... make sure you didn't do a 'Quick Connect'... that will do a wildcard and connect over any network. You want to specify your dedicated iSCSI network
No idea what the performance capabilities of the ReadyNas is... this could all likely be associated with the shared storage.
What speed NIC's are you using?   I hope at least 10 GB...
Hope that helps...
Elden
Hi Elden,
2. CSV is turned on, I have 4GB dedicated from each host to it. With IOmeter running within the VMs, I do see the read speed jumped up 4-5x fold but the write speed stays the same (which according to the doc it should). But even with the read
speed that high, the VMs are not starting up quickly.
4. I do not see any difference with IO with coordinator and non coordinator nodes.
5. I'm not 100% sure what your saying about my IPs. Maybe if I list it out, you can help explain further.
Host 1 - 192.168.0.241 (Host/LM IP), Undefined IP on the 192.168.0.x network (Hyper-V Port 1), Undefined IP on the 192.168.10.x network (Hyper- V port 2), 192.168.0.220 (iSCSI 1), 192.168.10.10 (iSCSI2), 192.168.20.10(iSCSI 3), 192.168.30.10 (iSCSI 4)
The Hyper-V ports are undefined because the VMs themselves have static ips.
0.220 host NIC connects with the .231 NIC of the NAS
10.10 host NIC connects with the 10.100 NIC of the NAS
20.10 host NIC connects with the 20.100 NIC of the NAS
30.10 host NIC connects with the 30.100 NIC of the NAS
Host 2 - 192.168.0.245 (Host/LM IP), Undefined IP on the 192.168.0.x network (Hyper-V Port 1), Undefined IP on the 192.168.10.x network (Hyper- V port 2), 192.168.0.221 (iSCSI 1), 192.168.10.20 (iSCSI2), 192.168.20.20(iSCSI 3), 192.168.30.20 (iSCSI 4)
The Hyper-V ports are undefined because the VMs themselves have static ips.
0.221 host NIC connects with the .231 NIC of the NAS
10.20 host NIC connects with the 10.100 NIC of the NAS
20.20 host NIC connects with the 20.100 NIC of the NAS
30.20 host NIC connects with the 30.100 NIC of the NAS
6. Binding orders are all correct.
7. Nic drivers are all updated. Didn't check the firmware.
8. I do not know about IPSec...let me look into it.
9. I did not do quick connect, each iscsi connection is defined using a specific source ip and specific target ip.
These are all 1gigabit nics, which is the reason why I have so many NICs...otherwise there would be no reason for me to have 4 iscsi connections.

Can I assign several physical storage locations for each virtual machine when using the replication-feature from Hyper-V 2012 R2?

Hi everyone,
I have 2x physical servers running Hyper-V 2012 R2. Each hosts several virtual machines. The VHDs of the VMs are stored on several dedicated physical disks to have a performance boost. For exampe if VM A has two VHDs attached I made sure that the VHDs are
on different physical disks to have them not slow-down each other in case of intensive disk accesses.
So far so good. I was looking forward to the replication-feature. The idea is to have the two physical servers have their primary running VMs being replicated to the other physical server and vice-versa. I was hoping to have the chance to choose for each
individual VM where the replicated VHD will be stored. But instead I can only see the one location/path which is configured in Hyper-V Manager when I activate the replication-feature on the server.
Is there by any chance a way how to select the storage location for each VHD/VM if using the replication-feature of Hyper-V 2012 R2?
Thanks in advance.
Cheers,
Sebastian

Secondly, you could replicate different VMs to different storage locations to perform some of the disk balancing you are trying to perform. Lastly, you could copy the vhd file to a different location
before starting the VM.
.:|:.:|:. tim
Hi Tim,
thanks for the reply. Sorry, but I had some other tasks to take care of, so I wasn't paying enough attention to this thread.
The part I quoted from your reply sounds exactly like the action I'd like to perform, but as you pointed out before this should not be possible.
How can I perform the action (replicating each VM to a storage location) as you mentioned secondly? To sum it up again:
2x physical machines carrying severel HDDs
8+ VMs spread to run on the 2x servers
when setting up replication I can only set the storage-location from server A on B and vice versa B on A
Thanks again for your reply.
Cheers,
Sebastian

RDS - Issue using Windows 10 build 9926 as Virtual Desktop Infrastructure on Hyper-V 2012 R2

We currently have a production Windows 8.1 as a VDI/RDS on Hyper-V 2012 R2. On testing the last build of Windows 10 (98??) we had no issues deploying this in same RDS as pooled desktops.
The latest build 9926, although correctly sysprep-ed (either by removing AppX modern apps that have been updated, or not connecting the template to the internet), the build is only ever partially successful. Some VMs build others do not, and the ones that
build cannot be managed via RDS/Server Manager, functions such as logging a user off with server manager, result in an error. (WTS API failed)
Build Error on connection Broker - Microsoft-Windows-TerminalServices-SessionBroker
VM host [HOSTSERVER05] failed to execute VM Provisioning operation [Task: To perform post processing actions at VMHostAgent:] for virtual machine [VDI-W10-57] in pool [VDI_Advanced_Te], Error: [Error code: 0x88130221.]
Any guidance on how to troubleshoot this would be greatly appreciated, although I suspect something regarding the auto-deployment/unattend and management systems though RDS no longer works with the latest Windows 10 build.
Already posted this in the
Windows Insider Program site, but was asked to re-post here. Thanks

OK, I've carried out some more testing on the client site and have been able to move a couple of existing VMs from their 2008 R2 Hyper-V server to the new 2012 R2 server.
Both VMs are Windows 7 SP1 with the RDP 8.0 update installed and I can connect to them from a Thin Client running RDP 7.1 and a laptop running RDP 8.0.
When I add the RemoteFX vGPU to them both I can still connect from both devices but, as suggested, when connecting from the laptop with RDP 8.0 I don't get the vGPU performance (but the vGPU is still shown in the device manager).
It all looks good at the moment but I'm still concerned as to why I was unable to connect to the first VM I moved over (it was complaining about a error in the License network communication or similar).
I'll keep testing and post anything else that might be useful.
Cheers for now

SLES 10 (SP3) on Hyper-V 2012 R2

I do realize that is unsupported (only SP4 supposedly is)
But I have SLES 10 (SP3) image that got converted from vSphere
Once I can boot the IDE disk (by editing menu.lst to /hda1 & uninstall Vmware Tools, I would need to get network connectivity, so logical step would be to use Intergration Services 2.1 (one that supports SLES 10 SP3)
But it is a no go. On make install during load of vmbus the whole VM just hangs & dies
http://imageshack.com/a/img545/7339/16u1.jpg
The initrd never even gets created as it dies & reset is the only option
If I rem-out vmbus start in Makefile then I can get new kernel installed, but restulting kernel will panic on VM boot
Anybody has any clever idea how to get it working (if at all possible)
Seb

Getting this to work is going to be difficult. The older LIS 2.1 does not work with Hyper-V 2012 and 2012 R2 due to changes in Hyper-V itself. But you could probably get SLES 10 SP3 with LIS 2.1 working if you went back to the older Hyper-V
2008 R2.
You are correct that the LIS 3.4 package is created only for the Red Hat (and CentOS) distros. It will not work with SLES releases.
We've gotten occasional requests to get SLES 10 working on Hyper-V 2012 and 2012 R2, and we're in conversations with SUSE about creating a combination that works. But we don't have anything to announce about a timeline. When/if we get something
working, it will most likely be SLES 10 SP4, since that's the most up-to-date version from the SLES 10 series.

Moving VMs From One Hyper-v 2012 R2 to Another Hyper-v 2012 R2

Hi everyone, was hoping for some help in something I am confused about
Currently I have SERVER1 running hyper-v 2012 R2
I want to move all my VMs (around 20) to SERVER2 also running Hyper-v 2012 R2
But I am confused on the best way to do this
1) should I just click on "MOVE" on SERVER1 to move to SERVER2?
2) Should I do an export and then import
3) should I setup replication from Server1 to Server2 and then do a failover?
4) or should I shut the VM down, copy the VHDX file and then create a new VM and use that VHDX
I just want to be cautious and use the best method to ensure it goes smooth and not worry about any corruption. Can anyone offer some advice?
thanks

It all depends on your environment and your current Hyper-V configuration.
I asume both servers are domain-member of the same domain and don't use SCVMM. If so, then make sure you do the following:
First enable the "Live Migration" feature in the Hyper-V settings on both Hyper-V Servers.
Make sure both Hyper-V Servers have a vSwitch configured with the same display name and connectivity. They must be somewhat identical, but not everything. As long as the connectivity is the same.
Make sure you have a location to store the VM files on SERVER2.
Then do a Live Migration from SERVER1 to SERVER2, follow the wizard. By using the Hyper-V Manager console on SERVER1.
NOTE1: Without computer certificates and Kerberos configuration on your Live Migration settings you cannot initiate a Live Migration from the Hyper-V Manager cconsole on SERVER2. With the default configuration, you have to login on (or connect
to) SERVER1 en then initiate the Live Migration.
NOTE2: If you can't configure the vSwitches the same. Then you have to shut down the VMs and do a Quick Migration. Then re-configure the VM network properties and power on the VMs.
I hope this information will help you goin on. If you need more detailed information use the following link:

Hyper-v 2012 R2 server core recommendations for single server setup

Hi All,
Next weekend I will be installing a brand new Dell 720 server for a client of mine.
I would like to hear some recommendations on how to install this hypervisor.
Let me state that I have had some experience with virtualization technology in the past with VMWARE ESXi.
This is a small client with under 10 users but I have learned that with the 2012 product offering you cannot get Small Business Server any more. I know Microsoft has Windows server 2012 Essentials but you would have to have Exchange server in the cloud which
my client does not want. He wants to run his Exchange server in house.
Also he needs Remote Desktop Services (Terminal Server) because his accounting application requires it.
He has an existing Windows 2003 domain controller that eventually has to be decommissioned because it is too old and slow.
So I thought I install Hyper-v 2012 R2 core on the new server and then create 2 VMs:
1) Windows 2012 STD to run as a secondary domain controller.
2) Windows 2012 STD member server with Exchange server 2013 and Remote Desktop Services role.
My questions here are these:
1) Do I install the Hypervisor in workgroup or domain mode?
2) When I am finished with the old server do I transfer the AD FSMO roles onto the VM that is acting as a domain controller?
The new server has 2 CPUs. How does Microsoft licensing go here? I know that Windows 2012 STD gives me 2 instances with the same product key on the same server for 1 CPU. What happens if you have 2?
Can someone give me some insight on how to go about this? I remember that I found this easier with VMWARE Esxi.
Now with Hyper-V I need to also get a management workstation with Windows 8 professional on it to manage the Hyper-V core server.
Thanks and regards
Alfred

In regard to the VM's:
1.) DC: If you're going to be installing a second domain controller that is 2012 R2, you might consider reading this guide first.
http://msmvps.com/blogs/mweber/archive/2012/07/30/upgrading-an-active-directory-domain-from-windows-server-2003-or-windows-server-2003-r2-to-windows-server-2012.aspx
2.) Exchange: Here's the guide for installing Exchange 2013 on Server 2012. I don't believe R2 is supported yet for 2013.
http://social.technet.microsoft.com/wiki/contents/articles/14506.how-to-install-exchange-2013-on-windows-server-2012.aspx
3.) Host: You'd install the host in domain mode....but that point may be moot after you read #5.
4.) FSMO: I would verify the health of the 2012 DC before moving the roles. All too often I'll see a new DC get stood up, sysvol won't be published, the engineer will be in a rush to move the FSMO's, and things get a little sideways. Ultimately
you don't HAVE to move the FSMO's until you are ready to decommission the 2003 box.
5.) Licensing: No licensing rights convey with Hyper-V Core, so this may not be best for your scenario. See the queen mother of all Hyper-V licensing posts here -

For what it's worth, plenty of SMB's are going to Office 365 to avoid the on-prem administration headache, but your client wants what your client wants. Sorry if this isn't the news you wanted but I hope it helps.
