Hi,

So, I have a weird issue regarding 2 hyper-v core servers 2012 R2

If I use a machine on the same network as the management IP of the hyper-v servers, I can use hyper-v manager perfectly fine to manage the servers.

If the machine is not on the same network, I end up with RPC issues:

* the first server, shows in hyper-v manager, but fails to load the vm with RPC server unavailable. Unable to establish communication....

* the second server does not even want to show up in hyper-v manager

if I use 5nine manager:

* the first server shows and the VMs load

* the second server fail with RPC unavailable.

I have ran hvremote which detects no issue at all except that the firewall on the servers are down (normal as i am troubleshooting)

I can ping / rdp / powershell perfectly fine.

Also, for the second server, when I launch powershell from the command prompt:

* Attempting to perform the InitializeDefaultDrives operation on the 'FileSystem' provider failed.

But the first one does not have an issue.

If anyone could point me in the right direction, it will be appreciated :)

Hi all,

I have been running Windows 8.1 and in Hyper-V Manager, i can see 2 VM ( 1 Linux-Ubuntu , 1 Win 7 ) for couple of months.

Few days ago as usual i wanted to connect one of them while they were running but it did not work. I tried actions below already:

- Checked the event logs and they were saying vmconnect is crashing

- add new VM, delete existing one

-add/delete/modify virtual swtich and add/delete/modify virtual switch accordingly the connected VM

- restart Hyper-V Management services from services.msc

I dont know what is going on... When i open Hyper-V Manager i can start/stop VMs and i can see from preview that they are running.

We have some Windows 2012 R2 Hyper-V with dozens of VM running legacy systems and some departmental systems (XP, Win2003, Win2008, Win2012R2). They had worked for years without any problem.

In last December, we approve the monthly Windows Updates in the guest systems. In the next day, our IBM x3650 hosts presented disk errors and hanged, losing the disk array after restarted.

The host system logs had these records on Windows event viewer:

• Megasas2 – ID 129 – reset to device, \device\raidport0, was issued.
• Disk – ID 153 - the IO operation at logical block address 0x… for disk 2 (PDO: \device\0000005d) was retried.
• Megasas2 – ID 11 - the driver detected a controller error on \device\raidport0

The systems running on HP DL160/360 were not affected. The problematic environment is IBM x3650 M4 HD 5460 configured to boot from internal LSI MegaRAID M5210e. We are using fixed VHDX.

All diagnosis made after reboot have no errors and the hosts work fine after reinstall until an updated guest is started. VM guests run normally in another environment.

With this, we have tried to reinstall the host system using all versions of LSI MEGASAS drivers that we can, with or without Windows updates in host OS. In all attempts, we have a server crash and disk array loss when a guest starts.

Has anyone experienced this problem? How can we confirm that this is a driver issue?

Hi, we have Hyper-V Extended Replicas that for some reason quit replicating and when we go in and try to get them to replicate they never catch up. Is there something we can do or do we have to start all over again with new extended replicas for each server, this is at an offsite location and some servers have several TB of data. If we have to start over, which we have done in the past, we have to export the replica to external disk then physically take it over to the site, plug it in and do an import. Is there another solution?

Hi MS Team,

As per our conversation, We have procured 1 qty of MS Windows server 2012 R2 Standard Licenses and installed on our server and activated the same.

Also we have installed 2 no’s of Hyper-v with the same Operating system on the same server. We would like to understand the procedure to activate the Guest operating system installed.

Will it use the same BASE License key on both the Guest OS or any other procedure to activate the License for the same.

So please help us with any documentation or any email confirming the same.

Awaiting for your reply

I'm trying to setup a couple of new hosts who both appear to be suffering from the same issue. If I run Get-NetAdapterVmq I can see that the two physical NICs show enabled as True but the windows Team I have created shows as false and when I try to enable a VM on the host to use VMQ it never shows in the queue.

The settings against the team under Advanced show that it VMQ is set to enabled, I've created the TenGigVmqEnabled Reg key and set 1 as the value and SR-IOV is not enabled on the vSwitch for Hyper V.

I'm sure this is something I have missed but I'm struggling to find it.

Server is a HP Dl380 Gen9 with HP FlexFabirc 10GB NICS running the latest available drivers from HP.

We have two (will eventually be 4) nodes accessing 3 shared volumes. Hyperv r2 core installs. The volumes are okay and the cluster worked and we started migrating. Yesterday the problems started.

At the moment only the owner of the volume will stay connected when running machines from the same volume. So machines on hyperv1 stop hyperv2 gaining access to the shared cluster volume. Event ID: 5120 Event ID: 5142

i had to migrate machines to another volume before hyperv2 got access back. so now we have 3 shared volumes that can't be shared between nodes.

Suggested solutions don't work because the applets aren't included in the core install. None of the answers i've found have shown how to deal with core installs.http://support.microsoft.com/kb/2008795/en-au

From what i've been able to gather it's a problem with the cluster NIC's how do i change these without causing everything to fail?  http://itbloggen.se/cs/blogs/micke/archive/2009/10/26/cluster-shared-volumes-and-iscsi-could-be-a-problem.aspx

Servers are Acer Altos R720's.

Thanks.

I was exporting several VM's from a Vhost so that i could import them into a new cluster. Four out of the five machines went off with no hitch and were exported and then imported.  However one of the machines throws up an error durring the export

Hello!

Consider the following testing environment: there're two host machines - HOST1 and HOST2 - (Core i5, 16Gb RAM, 3 Nics, one of the nics -HV - is used for test VMs) that host one VM each (now they are "DC" and "EXCH1"). These VMs are connected by the 5-port 1Gb switch UPVEIL.

All operating systems (both for host and virtual machines) are Windows Server 2012R2.

To make sure VM1 can communicate with VM2 I run on VM1 "ping VM2 -t" - there would be NO any packet loss however many minutes/hours thisping continues.

When any action starts that require a bit more network traffic to pass from VM1 to VM2 or vice versa (copying files, connecting to the other VM's Computer Management console...) the network communication stops after several seconds:

After some timeout it resumes and the process of stopping/resuming may be repeated several times or the operation may never be completed at all.

Exactly the same Nics and switch operate perfect when connecting HOSTs (NOT the VMs) - the problem arises ONLY between VMs (Hyper-V).

I did this test many times with different Nics and different switches - no problems exist until the Nics start to get used by Hyper-V.

???

Thank you in advance,

Michael

Hello,

I have a Windows Server 2012 R2 Standard server with Hyper-V, where there is a VM.  Hyper-V Manager is 6.3.9600.16384 is used.

The VM was created and at that time it was able to authenticate accounts from anther domain.  The VM is in one domain, say Domain A, and the VM and applications on the VM was able to use accounts in another domain, say Domain B.  Doman A and Domain B had a trusted relationship and all was working great on the VM and other servers in Domain A.

Then, the trusted relationship was broken.  The applications and the VM still worked, but you could not add and use accounts in Domain B.  Applications using accounts in Domain B could be not be authenticated either.

Then, recently we fixed the broken relationship between the two domains.  However, on the VM, accounts from Domain B could not be added to applications and could not be authenticated nor used, even though other servers in Domain A had accounts from Domain B working again.

What can be done to get the VM to recognized accounts in Domain B, now that the trusted relationship is working again between to two domains?

There is Hyper-V cluster with 2 nodes. Windows Server 2012 R2 is used as operating system.

Trying to live migrate test VM from node 1 to node 2 and get error 21502:

Live migration of 'Virtual Machine test' failed.
'Virtual Machine test' failed to fixup network settings. Verify VM settings and update them as necessary.

VM has Network Adapter connected to Virtual switch. This vSwitch has Private network as connection type.

If I set virtual switch property to "Not connected" in Network Adapter settings of VM I get successful migration.

All VM's that are not connected to any private networks (virtual switches with private network connection type) can be live migrated without any issues.

Is there any official reference related to Hyper-V live migration of VM's that have "private network" connection type?

Ok so I want to set up a test lab at home for study and testing purposes. I'm running Hyper-V from my Win 8.1 host pc (i7 Quad core, 16GB RAM with 2 1TB HDD)
I want to set up the following VMs: 1 x Domain controller with AD, DHCP & DNS running on Server 2012. 1 x SQL 2012 Server. 1 x SCCM/SOCM 2012 Server. 1 x Win 7 Packaging PC. 1 x Win7 Test Client & 1 x Win8 Test client.
I'm using a Virgin Super Hub2 which I've been informed will support what I'm trying to achieve. After reading loads of forums regarding the networking side of things I'm still no further forward :(I believe I need to use Virtual networ manager to create an internal switch to connect all the vms to each other but I'm struggling on how to set the DC to use DHCP to provide internet access to the test clients? My ultimate aim is to package apps, import them into sccm and then deploy to my test clients. Am i looking at this the right way? I've created an internal switch which all vms are connected to and I've created an external switch which i have given the DC access to which has allowed me to update the DC but my aim is get dhcp on the dc to give out ips to the other vms and give the test clients internet access whilst allowing them to join the domain. PLEASE HELP?
