Windows 2012 R2 hyper-v network unable to connect to outside resources

Today, I went and upgraded a Windows 2008 R2 machine to 2012 R2. I did a clean install and have never seen this problem before in this fashion. It is a HP 370G6 with an HP NC375I quad card. Only 1 adapter is in use, so it is not teamed.
After installing, none of my VM's will communicate to outside resources. I got the Windows 2012 R2 update package from HP dated 4/14. My virtual switch manager is set to Allow management operating system to share this adapter. The adapter
type is set to External. After playing around with 1 guest, I finally have it communicating with the rest of the network. However, my other guests will not. I have checked all IP's multiple times, no differences but the last octet.
I can not figure out what is allowing my 1 guest to now communicate, but the others to not. It is driving me crazy! I have tried adding and removing the adapter several times, and also tried using the Legacy NIC to no avail

Hi,
The external
virtual switch vm can can’t access the outside resource issue we found most of them were pointing to the VMQ, we can try to disable the VMQ, here is the steps:
Powershell command:
Disable-NetAdapterVmq –Name NIC_CARD_NAME
You can refer to the following article for more about the VMQ:

High Network Utilization on HeartBeat and LiveMigration networks - Windows 2012 R2 Hyper-V cluster

Hi all,
I have just setup a fresh Windows 2012 R2 Hyper-V cluster with 4 nodes.
Config:
Network:
2 x Networks for iSCSI
1 x VM network 1
1 x VM network 2
1 x Heartbeat
1 x LiveMigration
Disks:
5 GB = Quorum
2 x 2.99 TB (Deduplication enabled)
The problem I am getting is that HeartBeat and LiveMigration (both configured with Cluster Only traffic) have alot of traffic on them even though no LiveMigration (the only card configured for LiveMigration) is going on.
All network configuration is the same as it was in Windows 2008 R2 SP1 cluster which these machines where running before (not upgrade, fresh install and migration) and did not have this "problem".
Has anyone experienced this or have a solution to this?
Regards,
Thorir

Windows 2008 r2 guests blue screen on Windows 2012 R2 Hyper-V Cluster with e5 2670-v2 processors

Hello all,
We have a new hyper-v infrastructure deployed in two brand new Dell R720 Servers with 384GB of Memory and dual Intel e5 2670-v2 processors. This infrastructure is replacing an existing hyper-v 2008 R2 and all the guests are being migrated to this new cluster.
The issue we are seeing is our 2008 r2 guests blue screening ocasionally with 0x0000001a,0x0000004e or 0x00000050 bugchecks.
All this guests are configured with dynamic memory and with the integration components up to date. These same guests were running with no problems in the hyper-v 2008r2 cluster.
When searching i found this article from vmware that pretty much describes what we are facing:
http://kb.vmware.com/selfservice/microsites/search.do?language=en_US&cmd=displayKC&externalId=2073791
Are you aware of the same problem with this kindd of hardware on windows 2012 r2 hyper-v?
Thanks!
Nuno Carvalho

Meanwhile i found this May 2014 update on the intel specification of the CPU we are using:
CA135 Incorrect Page Translation when EPT is enabled
Problem:
If EPT (Extended Page Tables) is enabled, then a complex sequence of internal processor events may result in unexpected page faults or use of incorrect page translations.
Implication:
Due to this erratum a guest may crash or experience unpredictable system behavior.
Workaround:
It is possible for the BIOS to contain a workaround for this erratum.
Status:
For the affected steppings, see the
Summary Tables of Changes.
This affects VMware as of the today update of the article i referenced in the first post, what about hyper-v?

Windows 2012 R2 Hyper-V event id's 20144 and 15130

Windows 2012 R2 Hyper-V.
After installing the May 2014 MS updates we can no longer start any of the guest VM's. When attempting to start a VM the following is logged in the event logs:
Event id 20144 from Hyper-V-VMMS "Failed to start the virtual machine XYZ' because one of the Hyper-V components is not running" and
Event id 15130 from Hyper-V-VMMS "XYZ' failed to start"
We've looked at http://support.microsoft.com/kb/2761004/en-us and as far as we see the I/O verification option in Driver Verifier is disabled.   We also uninstalled the May
2014 updates that we applied just before the problem started but this did not make a difference.
Help please.

Hi,
I don’t found the similar issue when update, but from the event id, it seems is the incompatible hardware driver, please try to update all your hardware driver and firmware.
Or you can try the following example command to confirm your Hyper-V service is running or not.

Windows 2012 R2 Hyper-V Server Boot cannot boot normally

I have a Windows 2012 R2 server with Hyper-V role installed.
The server will automatically reboot every few weeks.
Every time it reboot, the server will boot into the below screen instead of normally boot into windows.
I will need to manually startup the server in front of it.
Are there any ways to bypass the below "Choose an option" page?
I saw a related post in below, but it doesn't seems to be answered.

Hardware: IBM x3650 M4
Ps. My account cannot post Links & Image here

Hi TM Yung,
It seems the data in event viewer is crushed, so I recommend to troubleshoot this issue firstly to show the right content of the event id 41, then investigate the reboot issue depending on this even.
Please make sure you logon with Administrator and check if the related .evtx file exists under the path C:\Windows\System32\winevt\Logs.
If the steps above can't work, please also try a clean boot in case of the installed driver causes this issue.
To perform a clean boot, please follow this article, after troubleshooting, please refer to this section "How to reset the computer to start normally after clean boot troubleshooting" to start server normally:
How to perform a clean boot in Windows
If there is anything else regarding this issue, please feel free to post back.

High Page Pool Memory Usage on a Windows 2012 R2 Hyper-V Cluster

Hi,
may someone has a similar Problem or can give me a helping Hand.
I'm having a 9Node Cluster ( Windows 2012 R2 , fully Patched from RTM Version on )
The Cluster is connected to a SAN which is an Equallogic ( Firmware 6.11). HitKit Driver 4.7.1
The System running clean and without any Event Logs until the Page Pool Usage of the Nodes turn over 15 GB of Paged pool Memory.
I monitore that via a Performance Counter ( \Memory\Pool Paged Bytes)
otherwise I have no indication by for example the Process View, the Calculated Sum on the Overview ( TaskManager / Memory ) but shows on the contraditory the 15GB an Memory Usage.
I downloaded the RAMMap Tool from Sysinternals but that doesnt show me any possible Information for the information , acutally the Information differs from RAMMap to the Performance Counter ( RAMMap = 251MB, Performance Counter = 15GB )
Just to make that point clear , there is No Information beside the Sum of Page File on the System Page and the PerfCounter that so much Page Pool Memory is used by any Process . Therefor it is hidden which process "needs" it.
I tried many thinks , like search for a Memory Hole in the Drivers , Hyper-V Stack , Equallogic and hoped for resolution with any new Patch which had a "Memory Leak" Information to them , but so far none has made a difference , maybe someone
has the same Problem.
My Cluster has routher large VMs on it compared to the Numa Seize ( VM 4-128GB, on DELL R720 ( 2x CPU (8C) 384GB RAM )
( The VMs have also a High IO Usage , as there RAM is used as a RAM Database ( zb. Mongo DB ) )
Regards
M

Hi Alex,
there is something wrong here and not an "normal" Memory Leak , as for that reason I would see the amount of Page Pool Memory assigned to a given Process.
If that would be the Case I could use RAMMap or even Vmmap to adresse the Paged Pool usage, but those Tools dont reflect the Usage like the PerfCounter does.
The Windows Driver Kit for a 2012 R2 System is WDK 8.1 which has a necessity of VS2013 ( Important: Before
installing WDK 8.1 Update, you need to install Visual Studio 2013. See the Visual Studio links on this page.) My Last Hope was to get poolmon.exe and identify the Source for the "Paged Pool" Usage .
We are having that Problem now since the Early Days of Windows 2012R2 and because the Usage is quite "hidden" we only found out , when we ran out of Memory without knowing why.
Worst Usage Rates where up to 150GB of Paged Pool !! given a RAM 385GB ( Dell R720) that is quite a Number.
Im wondering if noone else with a cluster ( seems that the Node numbers in a Cluster and the "RAM" Seize of the VM ( >32GB ) have a tremendous impact on that given Problem , with a 4 Node Cluster the Problem isnt so big )

Exporting and Importing Virtual servers with Windows 2012 R2 Hyper V

Hi
We are looking for various options / best practice in exporting and importing VSs between Windows 2012 R2 servers. Live migration we tested between servers in same VLAN and it's fine, but some servers are in different VLAN and hardware firewall is there
in between. So we exported the VS and while importing it, there is no option to export each Virtual disk to separate partitions / LUNs. Is it fine to create a new VS in the new server and just copy the VDs from the other HV host server, or exporting and importing
is the only proper method?
Thanks in advance
LMS

Hi Laljeev,
Please allow me to state my understanding of the two methods :
1.when you want to copy vhd you may need to shutdown the VM , further more if there is some snapshots I think it will be a trouble .
2. "export" you still need to shutdown VM but it doesn't have the trouble with snapshots .
The other way I will use is , "move" all of the VM's data to external disk then import it into destination hyper-v server (it can decrease the off-line time of VMs).
Best Regards
Elton Ji

Elton, in Windows Server 2012 R2, we do not need to show down the VM to export it via the Hyper-V Manager GUI or Powershell...

Windows 2012 R2 Hyper-V and NVGRE

Running Windows 2012 R2 with SC-VMM 2012 R2 SP1 with the Windows Gateway Service Template.
Whenever I start the Windows Gateway VMs we experience network degradation and packet loss on the Provider Network with is the host management native vlan.
My Physical Environment is Cisco 6248 with Nexus 5500s.

Did you get anywhere with this? I've a similar issue... an NVGRE device failed in the PoC, and now I can't remove the networks, subnets etc.
I had to remove the subnets using powershell and the -force parameter, but can't remove the network service itself as it's attempting to communicate with the NVGRE VM. I just want to remove the service so that I can start from scratch with a new NVGRE VM...

How to obtain target WWN for a LUN On Windows 2012 R2 Hyper-V with Fibre Channel SAN

I have a large collection of Hyper-V hosts for which I would like to retrieve the target WNN and LUN ID for the LUNs visible on each host. By target WWN I mean the storage array's WWN.
I have tried using the root\wmi namespace to retrieve MS_SMHBA_PORT_LUN instances, but I get 0 instances back.
I get instances of MSFC_FibrePortHBAAttributes back, but those only tell me the local host's HBA WWN, not the target information.
This information must be stored somewhere, because you can't access the LUN without it, I hope there is a way to retrieve it. Is there? Or is it write only during LUN setup?

Networking - unable to connect a macbook w 10.9.2 to Windows 2003 network

Hello,
I've never had this issue on a Mac before.
The machine must run on a wireless network.
I enabled that, making sure it could ping internal and external IP addresses.
It gets an address via DHCP, can access external sites, and can ping internal ones.
So, I went to join it to the intranet.
Despite specifying the preferred ADC (used "Active Directory method to try to connect), via IP address, every time I go to bind the machine to the network I receive this error:
"authentication server could not be contacted"
We don't use LDAP at this site.
Any assistance would be appreciated.

Checking the Canon Australia web site the iR2016 lists UFR2 and PCL5e/PCL6 as supported print languages. Postscript was an option and given that the Generic PS did not work then it would be safe to assume that this option is not installed.
If you have installed the UFR2 v1.80 driver then you add this printer by selecting More Printers > Canon IP (UFR II). If you have installed the v2.xx driver then you simply select IP > LPD for the protocol. This then requires you to enter the IP address of the iR2016 and then you can browse for the iR2016 in the Print Using menu. However this is for a direct IP connection. You cannot use the UFR2 driver via the Windows share, which you mention trying.
So if the printer has its own Ethernet connection to the network then select to add the queue using IP > LPD, enter the IP address of the iR2016 and in the Print Using menu type 2016 to filter the list to the correct model. It should show UFRII in the name. Select this and you should be able to print.
