Guest on Hyper-V Host hung up at logging off, have no access to server

I have a Hyper-V guest that is hung up at logging off and have no access to that server?

Hi Sherryd,
Please take a hard shutdown of that virtual machine, then start it again, press F8 then choose the last good start up, after you logon on the system you can check your whether event has recorded some unexpected error code, if it related some recent installed
software please try to uninstall this application then monitor the issue again.

How to get low performances alert for Hyper-v Host ON scom

Hello Expert,
We have to implement a scenario VM Live migration which involved (SCOM,SCVMM,SCORCH Parts).
where SCOM parts will monitor the performances of SCVMM 's Hyper-V hosts and VMs running the within the Hyper-v hosts.
when the VMs utilization exceed the threshold and then scom monitor checks the performances of Running Hyper-v Hosts ,then using SCORCH automation ,VMs are moved to one of the best performances the Hyper-v hosts.
To implement this ,I have integrated SCOM 2012 R2 AND SCVMM 2012 R2 AND enabled the PRO Tips.
but don't know how to get alerts and configured related to performances of VMs and Hyper-v host.
What will be next needed to achieved this from SCOM PARTS.
Thanks and Regards

Hyper V hosts with Cluster Shared Volume do not provide Shared VHDX ability

Hi there, i've configured a pair of Hyper V hosts (UCS B230 M2) with SAN-Boot and access to a Shared Fiber Channel LUN.
No matter what I try, when I add a SCSI Adapter and one VHDX virtual disk to a VM, the option for "Advanced" never shows up therefore I can not share the VHDX file between another VM, which prevents any VM based clustering from working (IE: Clustered
SQL server)
Here are the settings I have configured:
The LUN has been formatted with NTFS
The Hyper V hosts have been configured as a Windows Cluster with an IP address and the Fiber Channel LUN configured as a Cluster Shared Volume
I follows the guides below
Create a CSV
https://technet.microsoft.com/en-us/library/dn265980.aspx
Create a shared VHDX
https://technet.microsoft.com/en-us/library/dn282283.aspx
Further details:
Two HyperV server core hosts built
Both joined to AD
Both joined to a Windows failover cluster
One 2TB Fibre Channel LUN presented from an EMC VNX array to both hosts
LUN formatted as NTFS
LUN created as a Cluster Shared Volume
Cluster Shared Volume present on both HyperV hosts
VM created within the Cluster Shared Volume
VM Booted up and Windows 2012 has been installed
VM gracefully shut down
Through the HyperV Manager, going in to VM settings,create a SCSI adapter, create a new VHDX file inside the CSV, the “Advanced” option for the VHDX is not present, therefore the option to make the VHDX file shared is not available
I have followed all steps in the Microsft Technet pages to create a CSV and a VM with Shared VHDX
I’ve cleared all settings and restarted multiple times, but this option is not present

Hi Sir,
>>No matter what I try, when I add a SCSI Adapter and one VHDX virtual disk to a VM, the option for "Advanced" never shows up therefore I can not share the VHDX file between another VM
>>Yes we are using Hyper-V Server 2012 R2
As we know Hyper-v server 2012R2 is a free version without GUI , I'm afraid you are not using Win 8.1 or other windows server 2012R2 to manage that free version hyper-v server .
Shared vhdx is a new feature came with 2012R2 , if use previous windows to manage 2012R2 you will not see "advanced" option (The blue circle belongs 2012 , the red circle belongs to 2012R2 ):

Enabling VM Guest NLB w/Multicast IGMP on 2012 Hyper-V host w/ converged SCVMM fabric switch

What a mouthful.
As short as possible:
WHAT I'M ATTEMPTING:
I'm trying to build a new NLB cluster for a 2008 R2 SP1 Remote Desktop Services farm. And I'm trying to do it the right way, with multicast igmp, not unicast.
The two guest VMs with NLB install converge fine. VIP gets this:
IP: 192.168.100.157
MAC: 01-00-5e-7f-64-9d
NLB NIC is on the same VLAN & "Converged switch" in VMM as our mgmt/server traffic (That is to say it's on production VLAN, not on a separate vlan)
PROBLEM:
Can't ping 100.157. From VM guest itself, from host, or from Cisco 6509 switch.
Cisco show mac address lookup does not see that MAC anywhere
show ip igmp groups shows not igmp traffic at all. Clearing counters show sno multicast increment.
FURTHERMORE:
Host is setup thusly:
- Dell R810
- 8x1GbE Broadcom 5709c in a Server 2012 LACP/HASH team built via VMM powershell cmdlets
- On the physical switch side, those 8 nics are in a Cisco port-channel, trunked, all VLANs allowed
- Host has no "physical" nics per se, as in a 2008 R2 hyper-v host. Instead Host has these:
Set-VMNetworkAdapter -ManagementOS -Name "Live Migrate" -MinimumBandwidthWeight 35
Set-VMNetworkAdapter -ManagementOS -Name "MGMT" -MinimumBandwidthWeight 25
Set-VMNetworkAdapter -ManagementOS -Name "CSV" -MinimumBandwidthWeight 40

Set-VMNetworkAdapter -ManagementOS -Name "iSCSI #2" -MinimumBandwidthWeight 0
Set-VMNetworkAdapter -ManagementOS -Name "Aux" -MinimumBandwidthWeight 0

Question:
Aside from a few of my favorite MS MVPs (shout out to
WorkingHardInIt for having this same question), I can't find much documentation on employing 2008 R2 NLB on guest VM within a fabric-oriented, VMM-built 2012 Hyper-Visor converged switch (no network virtualization...yet).
Yes I know all about VMM NLB but 1) I'm trying to wedge NLB in after building these VMs without a service template (NLB is the audible, essentially) and 2) MS NLB is configured in providers & I've created requisite VIP templates.
Even so, I ought to be able to create an NLB cluster without VMM's assistance in this scenario correct? Suboptimal, I know but possible, yes? Essentially I've put to synthetic NICs on each VM, set IPs manually, and assigned them to the same vlan. I can ping
each synthetic NIC, but not the cluster IP.
And yes: these particular vNICs have Mac Address Spoofing enabled.
Cisco:
I have a TAC case open with Cisco, but they can't quite figure it out either. IGMP Snooping enabled across the switch. And they insist that the old static arp entry to resolve this problem is no longer necessary, that Microsoft now complies with relevant
RFCs
Possible SOlution:
Only thing I can think of is flipping MulticastForwarding param below from disabled to enabled. Anybody ever tried it on a converged virtual switch on the Hyper visor? Is my virtual converged switch protecting
me from multicast igmp packets?

Sorry for the poor follow-up Steven. We are using Server 2012 Hyper-V, not VMWare, on the hosts. You can close this but for the benefit of anyone who comes across it:
After working with Cisco, we decided not to implement multicast IGMP. Cisco says you still need to create a static ARP entry on the physical switch, though my cluster IP address & Microsoft NLB 2008 R2 were set up with igmp multicast, not multicast or
unicast. Here was his email:
Yes, we will need the static mapping for the NLB server in this case because the NLB mac address is multicast and the IP address is unicast. I was under the impression that even the server would be using IGMP but that’s not
the case. We won’t need to do the mapping for the nodes though if they use IGMP. To this end, following is the configuration that should make this work.rp 192.168.100.157
0100.5e7f.649d arpa
<u5:p></u5:p>
mac address-table static 0000.0000.649d vlan <> interface <> disable-snooping
ßThis is the switch interface where the NLB server is located<u5:p></u5:p>
interface vlan<>
<u5:p></u5:p>
ip pim sparse-dense-mode <- This is needed for the switch to elicit IGMP joins from the nodes<u5:p></u5:p>
end<u5:p></u5:p>
I don't think it got through to him that there was a virtual Layer 2/3 Hyper-V switch on top of 8 teamed GbE interfaces in LACP/hash. "Where the NLB server is located" = 1)a Cisco port-channel bound to one of six physical hosts; the NLB VM itself could be
on any of those port channels at any given time (We have a six node Hyper-V cluster).
Once I enabled pim I did see activity; but we killed this later as we realized we'd have to implement the same on 40+ managed routers globally
Anyway we further would have had to implement this across managed routers at 40 sites globally according to Cisco.

Hi,
Please refer to the following post to see whether you can resolve the issue.
Network Adapter (not Legacy) does not work on Virtual Machine after installation through ISO

Hyper-V host server upgrade from Server 2008 R2 Enterprise SP1 to Server 2012 R2 Datacentre

We are about to upgrade our Hyper-V host servers from Server 2008R2 Enterprise SP1 to Server 2012 R2 Datacentre to take advantage of the latest Hyper-V features.
This only concerns the host servers and not the guest VMs running on the hosts (they will be upgraded next year).
This is what is running on our host servers:
Host 1
File,print & issuing CA server
Exchange 2010
SharePoint 2010
Quickbooks server
Domain controller 1
Offline CRL CA
Host 2
SQL 2008
Forefront TMG 2010
Domain Controller 2
Windows 7 client
With this is mind, I have drafted a rough action plan as follows:
Create a list of all file locations for VM memory, snapshots, virtual memory and Hyper-V config files
Document all existing system settings
Gather server information, download drivers, RAID controller and other boot drivers & firmware updates (in case the in-place upgrade fails)
Test all software media
Copy all VMs onto external data storage (NAS drive)
As part of the upgrade process we will redistribute some hard drive space i.e.
expand them to their new sizes and verify the data integrity of copied VMs by powering up each VM in a test environment
Wipe and adjust the sizes of the host partitions to accommodate the expanded VMs
Perform an in-place upgrade to Server 2012 R2 Datacenter
Check EV, services etc
Change the default locations for VM memory, snapshots, virtual memory and Hyper-V config files
Upgrade Anti-virus and other system software
Test the system
Are there any glaring omissions? Does anyone have any tips they can give me?

Hi Marco,
always do a fresh Installation of your hyper-V Hosts, you could end up doing a lot of Troubleshooting with Drivers,Addons etc.. new Installation ist way faster.
Depending if you have a Cluster or Standalone Servers there are different ways to do it.
When you have installed your 2012 R2 Hyper-V Server you just can Import the VMs from the new Location.
As far as i know VMs with snapshots are not supported, so you have to remove them before doing that move and commit the changes to the vhd files, the VM need to be offline on 2008R2 to do that.
You do not Need to Export the VMs on 2008R2, just copy it, normaly you should have all Files of a VM in one Folder.
A working Backup is always your friend on such Tasks.
When the VMs are running on Hyper-V 2012R2 do not forget to Update the Integration Services.
Make Sure your Servers Hardware are still supported with 2012R2, see Server Catalog and Support Matrix of the Vendor.
And last one, where possible and supported convert the VHDs to VHDx Disks, after testing the first boot of the VM.

Hyper V Hosts and Domains

Can I have hyper V hosts connected to one domain then connect a VM to another domain.
I have three Quad port NICs- two will be connected to my DMZ domain and then to accommodate direct access I propose connecting one to my corporate LAN. I will then create the required vswitchs and place my direct access servers on DMZ switch and
the LAN switch for a 2 leg deployment?
Your thoughts please?

Sure, no problem with that. Each OS whether physical host or guest VM can join any domain they can reach.

Linux VM KVP IP can't be shown on Hyper-V Manager after querying its KVP/IP information on Hyper-V host several times

Hello
[Sorry for asking the same question in the wrong place/forum of "Hyper-V"]
I am using a CentOS 6.5 VM (Linux kernel 2.6.32-431) and (generation 2) CentOS 7 VM (Linux
kernel 3.10.0-123) with Hyper-V KVP daemon installed,
and I periodically query its IP (via using WMI or Powershell to query its KVP information) to manage it.
However, after querying its IP (KVP) for several times, its IP can’t
be queried or shown on Hyper-V Manager anymore (Windows VM is ok without this problem).
And here is the vmIntegrationService status of my CentOS 7 VM for the references.
PS C:\Users\Administrator> (Get-VM -name G2_CentOS7).vmIntegrationService
VMName Name Enabled PrimaryStatusDescription SecondaryStatusDescription
G2_CentOS7 Time Synchronization True OK
G2_CentOS7 Heartbeat True OK
G2_CentOS7 Key-Value Pair Exchange True OK The protocol version of the component installed ...
G2_CentOS7 Shutdown True OK
G2_CentOS7 VSS True No Contact
G2_CentOS7 Guest Service Interface False OK
I attached a simple KVP query Powershell script as
the follows, and this problem can be reproduced in couple minutes if you run two instances with this script at the same time.
$VMName = $args[0]
write-host "$VMName"
filter Import-CimXml
$CimXml = [Xml]$_
$CimObj = New-Object -TypeName System.Object
foreach ($CimProperty in $CimXml.SelectNodes("/INSTANCE/PROPERTY"))
if ($CimProperty.Name -eq "Name" -or $CimProperty.Name -eq "Data")
$CimObj | Add-Member -MemberType NoteProperty -Name $CimProperty.NAME -Value $CimProperty.VALUE
$CimObj
$CimObj = $null
for ($i=1 ; $i -le 10000 ; $i++) {
$a = Get-Date
write-host "$i - Time: " $a.ToLocalTime()
$vm = Get-WmiObject -Namespace root\virtualization\v2 -Query "Select * From Msvm_ComputerSystem Where ElementName='$VMName'"
$vm.ElementName
$vmkvp = Get-WmiObject -Namespace root\virtualization\v2 -Query "Associators of {$vm} Where AssocClass=Msvm_SystemDevice ResultClass=Msvm_KvpExchangeComponent"
$vmkvp.GuestIntrinsicExchangeItems | Import-CimXml
Actually, if your CentOS VM (has LIS) installed with KVP daemon running well,
my test script will show more than 4 keys (include NetworkAddressIPv4 or NetworkAddressIPv6 keys).
However, while the KVP daemon becomes problematic, it will only show a few keys
(ex. 4~6 keys) and at this moment, Hyper-V Manager also can't show IP address of it anymore and you may need to reboot the CentOS VM to recover it.
For example (KVP in 252 time is good, but KVP in 253 and 254 times become problematic)

I
found the following patches and gave them a try, but the
problem still remains after applying these patches and the (generation 2) Ubuntu 14.04 with Linux kernel 3.13 also has this problem.
- Patch "Drivers:
hv: util: Fix a bug in the KVP code" has been added to the 3.14-stable tree
- Drivers: hv: vmbus: Fix a bug in the channel callback dispatch code
But (generation 1) Ubuntu 14.04 VM with Linux kernel 3.17 doesn't encounter this problem after querying its KVP/IP information on Hyper-V host several times.
Does anyone know what changes between Linux kernel 3.13 and 3.17 fix this issue?
Thanks,
Paul

Hi Dexuan and Mike,
Thanks for your help!
I did the patch with rpmbuild on CentOS 6.5 (with kernel 2.6.32-431).
However, the second patch cannot patch on CentOS6.5 since there is no target_cpu in such version.
So we are patching that with the following similar patch but this issue still occurs. (also replace ko in initrd)
https://lists.ubuntu.com/archives/kernel-team/2014-August/047725.html
Can you tell me if any patch I could miss or any suggestion?
Thanks for your time.

Can a SQL Server Failover Cluster Instance (FCI) be Implemented Between Two Hyper-V Hosted Virtual Machines?

I haven't had the opportunity to implement a SQL Server Failover Cluster Instance (FCI) for over 10 years and that was done with two physical, identical database servers way back in the day of Windows Server 2003 and SQL Server 2000 (old school).
Can a SQL Server 2008 R2 Failover Cluster Instance (FCI) be implemented between two Hyper-V hosted virtual machines? The environment in question already has Windows Server 2012 R2 Hyper-V hosts in place, so I'm just looking to see if this is even
possible and/or supported when utilizing virtual machines.
The client in question is currently using SQL Server 2008 R2 instances running on Win2008R2, Win2012, and Win2012R2, but I'd also be interested how this can be done or not with SQL Server 2012 or 2014 as well. Thanks in advance.
Bill Thacker

Yes, it can be done with Hyper-V guests. In fact, with Windows Server 2012 R2 Hyper-V, guests can use the Shared VHDX feature for shared storage used by Windows clusters. The guests can run Windows Server 2008 and higher provided that the Hyper-V Integration
Services are installed to support Shared VHDX. The only challenge here is making the Hyper-V hosts highly available as well, running it on WSFC.

Hyper-V host 1Gbps NIC negotiated at 100 Mbps when used for Virtual Switch

Hi all,
Hoping someone can shed some light on this one as I’ve been trying to hunt down a solution for a week now.
Setup
HP ProLiant ML350 G6 with HP NC326i PCIe Dual Port Gigabit Server Adapter network adapters
Windows Server 2008 R2 Core with only the Hyper-V role installed
SBS 2011 installed as guest
Port 1 on Dual port NIC configured a physical port or management of Host only
Port 2 on Dual port NIC configured for use as an External Virtual Switch port for use by guests only
The issue is that the physical port connected to the Hyper-V virtual Switch negotiates with the network switch at 100 Mbps full duplex while the management port negotiates at 1 Gbps full duplex. All clients (brand new HP Z210 workstations) also negotiate
with the switch at 1 Gbps.
During file copies and backups the network port connected to the Virtual Switch does not show any errors and transfers data at close to 100 Mbps. File transfers between individual workstations and workstations and server core again show no errors, but transfers
at 1 Gbps.
One observation is that the physical NIC connected to the Virtual Switch does not negotiate with the switch until the Hyper-V service has started (I’m guessing) the virtual switch.
Also, while staging the server the Hyper-V virtual switch created when the server was connected to a 100 Mbps switch not a 1Gbps switch as it is in production.
Has anyone encountered anything similar and if so how did you get the physical NIC to operate at full capabilities? Any assistance would be greatly appreciated.

Hi,
I purchased one gigabyte switch for home used several days ago, I just performed some copy tests between virtual machines and physical machines(not
Hyper-V host machine)in the same LAN, the average copy speed is 350Mb/s.

Vincent Hu

Disable guest aplication interaction during Host level backup

Hi,
I have a 3 nodes Hyper-V Cluster, the hosts are Windows 2012 R2 Datacenter.
Some of my guests are Windows Server 2008 R2 with Exchange 2010.
When i backup the Exchange VMs the guest is aware of the backup and it flush the transaction logs.
I want to disable this feature. Every solution I found refers to this KB:
http://support.microsoft.com/kb/975354
but this KB refers to Windows Server 2008 R2 Hyper-V host, I'm not sure that it applies also to Windows 2012 R2 Hyper-V hosts.
Is there somebody that tried on Windows Server 2012 Hyper-V host? Does it still apply?

How to get information about creation of a virtual machine on a Hyper-v host.

Hi,
How to get information about creation of a virtual machine on a Hyper-v host?
I need: host name, time created, creator user.
I saw in Hyper-V-VMMS but I found info about movements of VM between hosts.
Thank's in advance.
Denius Valiant

For Host Name * Created Time Use This Command In PowerShell
Get-VM -Name (Read-Host "Type Your Vm Name") |select CreationTime , ComputerName
and for Create User , As i know you should see on Event Log .
Go To Event Log Viewer--->Applications And Services Logs--->Microsoft--->Windows--->Hyper-V-VMMS--->Operational
You can see in Event Log who create the Vm.

i.e. Both of the VMs sync with Hyper-V host, instead the other host should sync with the PDC Emulator?
I run w32tm command and get the following result:
C:\Users\Administrator.DOMAIN8>w32tm /query /computer:dc8.domain8.local /source
VM IC Time Synchronization Provider
C:\Users\Administrator.DOMAIN8>w32tm /query /computer:hpvzh05.domain8.local /source
VM IC Time Synchronization Provider
HPVZH05.domain8.local works as PDC server.
How can I make DC8 sync with HPVZH05?

Awesome!
It looks like your PDC is successfully pulling time from an external source. DC8 is not longer pulling from Hyper-V so that is good.
When you set a client to pull from a source ( and in this case DC8 is pulling from NT5DS, which tells it to pull from the PDC), and it CAN'T pull from that source, it will default to Local CMOS Clock. This is likely an easy fix.
First, check connectivity:
- Method one- Download Portqry and run this command: portqry -n HPVZH05 -p both -e 123 and see if the results say listening, or
- Method two- Run this command from DC8: w32tm /stripchart /computer:HPVZH05
If you get any kind of error using method two, it's a connectivity issue. (Maybe you have a firewall that's blocking access?)
The other cause of this, and probably more likely in your case, is that your PDC isn't properly advertising as a reliable time source, so DC8 isn't 'allowed' to pull from it.
Try running this command on your PDC: w32tm /config /reliable:yes
Then go restart time on your PDC, THEN DC8 again. (net stop w32time & net start w32time)

VMM 2012 R2: error 410 / 0x80070001 when adding a new Hyper-V host. VMM Agent won't install automatically (status 1603)

I have several Windows Server 2012 R2 hosts. The OS is freshly installed, no roles/3d party software besides Hyper-V role). I also have a freshly installed VMM 2012 R2 server. They all are in the same AD domain. I want to manage those Hyper-V hosts
with this VMM instance, but I have troubles connecting those hosts to VMM.
Whenever I try to add a Hyper-V host in the VMM console, the process is stopped almost immediately after it starts. The failing step is "1.2 Install Virtual Machine Manager Agent". The final error message is as follows:
Error (410)
Agent installation failed on XXX.
Incorrect function (0x80070001)
Recommended Action
Try the operation again. If the problem persists, install the agent locally and then add the managed computer.
If I try to install the agent manually copied from the VMM host (C:\Program Files\Microsoft System Center 2012 R2\Virtual Machine Manager\agents\amd64\3.2.7634.0
as of now) by just clicking on its MSI file in Windows Explorer (and agreeing to the Windows prompt to run it with elevated privileges), the installation fails as well with "Installation success or error status: 1603." in the
server Application log.
The only way I found to install the agent is to run the installation from command prompt with elevated privileges. In this case the installation finishes successfully, and I can add the host to VMM by marking the "Reassociate the host" checkbox
in the VMM wizard.
Why is it so? Isn't the agent supposed to install without manual intervention? As I recall, I had no such problem with previous versions of Windows Server and VMM.

I brought up the share because it is off by default with Hyper-V Server as well as a Core installation. Regardless of the Firewall policy involved.
Maybe, but I don't work with pure Hyper-V and Core servers. I have a full-fledged Windows Server 2012 R2 Datacenter.
You're correct that File Server role is not enabled by default, this is my mistake. I open SMB-IN port manually (with the help of a group policy), and Windows considers it to be am equivalent of the enabled File Server role. Nonetheless, ADMIN$ share is
always accessible in my environment (and without it, for example, I wouldn't be able to remotely install things like SCOM Agent which installs without a glitch). Just in case I manually installed the File Server role, and it didn't help.
What you say about multihomed servers is interesting. The servers in question do have multiple network interfaces, but at the time I tried to install the VMM Agent only one of them (a designated host management / network access interface) had a real IP address.
Two other interfaces were non-configured (I apply a virtual switch configuration after the VMM Agent is installed). Just in case I disabled them when tried to install the VMM Agent remotely on the last host, and the installation still failed immediately
after start. Anyways, after the VMM Agent is installed manually the host can be normally re-associated with VMM, so it's doubtful that I have a network issue.
And, of course, there is no 3d-party software on the hosts (no antiviruses/firewalls in particular) except the EMC Unisphere Host Agent (a piece of software necessary for connecting a host to an EMC storage system) and networking drivers. Actually,
this is a pure Microsoft environment.
So I still believe that is has something to do with the Windows Installer inability to configure Windows Firewall policy after being invoked from Windows Explorer with a double-click on a MSI file. But I don't know how to strictly confirm it.
