SR-IOV PROBLEM TO ACTIVATE

February 9, 2016, 6:13 am

Hello
I have a windows server 2012R2 as host with Hyper-V role installed.
This host has 5 VMs, where three VMs are Windows 2012R2 and Windows 2008R2 VMs 2
I have 5 physical NICs on the host and all network cards are from the same manufacturer therefore has the same unit, the settings in the Networks unit boards are exactly alike.

5 Switches configured for virtual machines in the (external), with marked SRV-IOV, so configure the hardware acceleration in VMs configured with SR-IOV.

The server complies with all the conditions for SRV-IOV.

The problem is that only the VMs that are running Windows 2012R2, shows the network status with the SRV-IOV, VMs with Windows 2008 R2, only shows the status of the network as OK.

So I wonder if Windows 2008R2 is not entitled to SR-IOV?

Or if something is hidden in the configuration that did not?

Routing traffic from one IP from one Nic with two IPs to a virtual machine

Hello. I have a question for networking specialists. Because it's about a perhaps typical Hyper-V scenario i posted it here. Here we go:

I have a host with one nic. To this one nic the provider routes two external IPs IP1 and IP2. Hyper-V and Routing and Remote Access is installed on the host. I instantiated one Hyper-V virtual ethernet adapter "vEthernet (External)" with the external IP1 and IP2, external gateway and external DNS-servers and one Hyper-V virtual ethernet adapter "vEthernet (Internal)" with just the internal network gateway-address 192.168.0.1. The installed virtual machine has the fixed ip 192.168.0.10 and default gateway 192.168.0.1. Accessing the internet from the virtual machine is possible. Until now, no traffic is routed to the VM.

What do I need to do, to route all traffic coming in via IP2 over 192.168.0.1 to the vm with 192.168.0.10?

Each time I try to configure NAT, accessing the internet from the vm is not possible any more. Actual routing is:

Hi,

   I would like to ask for your expertise if it would be possible for our playout software integrated to Hyper-V? Here's the required minimum specification:

- Windows 7 Professional 64Bit

- Dual Core 2.0 GHz or faster CPU

- 3GB of RAM(dedicated) for 32 bit O.S. \ 8GB of RAM for 64 bit O.S.

- *Onboard video if CPU supports HD graphics 4000 or higher

- *Video card with 1GB of RAM

   As I can see that Hyper-V is moving forward that it can virtualize most of all application needed. Thank you for anyone who will respond.

Hyper-V 2012 R2 - Restart VMs after network/NAS/iSCSI failure

February 9, 2016, 8:15 pm

Hi there,

Is there a way to make sure all VMs on a Hyper-V Cluster, which are marked to autostart, actually restart after a severe network outage which completely disconnects all LUNs. Currently if iSCSI storage is disconnected from all nodes, Hyper-v trys to failover to another node, fails and then gives up. 

When the storage comes back online the VM remains in the failed state until manual intervention or the whole server is restarted. 

ESXi recognises storage disconnects and seamlessly restarts machines with storage interruptions once the storage comes back online.

Cheers

Capturing live migration and snapshot event in kernel for a vhdx

Hi, I am developing an fsfilter driver on windows 2012 r2. Job is to capture all the IOS happening on vhdx file which I am able to do. But I have no access to any documentation which talks about capturing live migration and snapshot event for vhdx in kernel because I want to do some pre and post processing on vhdx when live migration and snapshot operation is triggered. Can anybody help me on this? Just to clarify, this fsfilter sits on windows 2012r2 host where hyper-v is enabled. I do want to keep any component inside each VM for this purpose. So far, for snapshot - I check if any avhdx is created. If it is created then I know snapshot is triggered. However this is more of hack, I was thinking if there is msdn designed way to hold these operations (live migration& snapshot) in kernel (especially in fsfilter driver). Sorry, if I am attached to wrong forum. If yes then please guide me to right forum.

Remote Desktop manage over WORKGROUP

Hello

I've noticed that with all virtual machines in Hyper-V that are in same Domain you can set up Hyper-V management, but what about workgroup?

I don't want to use domain.

All virtual machines are in same WORKGROUP.

Now remote services  can "only" be managed over a domain?

Thanks

Hyperv migrate virtual machine to other hyperv

Hi there.

We have a standalone 2012 R2 OS with HYPERV role.
It contains 5 virtual machine (2domain controllers, 1 front end exchange server, 1 edge exchange server and 1 Linux).
We Will reinstall this HYPERV server because we need to reorganize RAID's on this server.

We have another server where we Will install 2012 R2 with HYPERV. Now the idea is to move virtual machines from HYPERV1 to HYPERV2, then reinstall HYPERV1 and put back virtual machines to it.
What would be the best way to migrate those virtual machines?

We thought about SHUTTING DOWN virtual machine on HYPERV1, manually copying Virtual Machine configuration Files and Virtual Machines HARD DISK's to HYPERV2 and start it there.
Do you recommend any other way?
Hyperv is not in CLUSTER mode, neither HYPERV1 or HYPERV2...

Initial Replication Failing

Hi - have to 2012 R2 Hyper-V hosts running 4 VM's each. All VM's are to be replicated to the opposite server. Managed to get all but one VM replicating. As soon as the wizard is complete, which normally comes up with Successful and starts the replication, it errors with message that there is an Invalid Parameter.  Wizard settings are exactly the same as all 7 other VM's that worked. There is plenty of space on the drive that hosts the replicas also on the opposite server.

Full Error: Enabling Replication Failed: Hyper-V operation failed because the specified parameter is no valid: 'IncludedDisks' is not valid for Hyper-V for virtual machine xxxxxxx: Invalid Parameter (0x80041008). (Virtual machine IDMachine ID).

There are 2 VHDX files for the server, both are fairly small (no bigger than ones that have worked) and both a fixed size.

Any ideas?

Hyper-V VMs export problem

Hello guys,

I have two servers, one is Windows Server 2012 R2, and second one is Hyper V Server 2012 core edition. I am trying to export my VMs (Hyper-V Server) to shared folder on our file server through Hyper-V Manager on Windows Server 2012 machine. And I am continuously failing to that. 

And I get a error:

"Failed to create export directory with error 'The user name or password is incorrect.'(0x8007052E)"

I add all rights to the shared folder, even "everyone" just for testing, I double checked NTFS level and share level permissions.

I also have some test VMs on my windows 10 machine and I successfully exported all Vms to the same shared folder, directly from Hyper-V manager (VMs and hyper-Manager on the same pc). Is there any suggestions,

Thanks, Z

Third party VM Backup fails when enable VSS

Hi,

We are using Veeam Backup and Replication 8 to backup SBS2008 SP2 virtual machine.  Veeam is installed on a workgroup Hyper-V host server running Windows Server 2012.  The SBS server is running SQL express, Exchange 2007 and SharePoint foundation. We started having issue recently with the VSS backup for the SBS server:

Hyper-V VSS writer retryable error when trying to backup with VSS enabled.  

This Hyper-V VSS writer error gets resolved after restarting VMM service on the host.

Also seeing Exchange related errors:

- Exchange VSS writer has unsuccessfully completed the backup of storage group.  No log files have been truncated for this storage group. Event 9782

- Information Store Shadow copyu instanace aborted.  Event 2007

We have tried:

- run Windows Server Backup with VSS full backup - Backup job completed successfully

- run Veeam backup with VSS disabled - Backup job completed successfully

However when we run vssadmin list writers on SBS server, it shows no error for the Exchange VSS writer.

We have already contacted Veeam and they have run some diagnostics and confirmed it is related to Windows Server.  

Could it be SQL or SharePoint VSS writiers interfering with Exchange VSS writer?

Please provide some assistance on how to resolve this issue.

Thanks

Migrate from HyperV 2008 R2 to HyperV 2012 R2

February 12, 2016, 12:06 am

Hi All,

I have a Windows Server 2008 R2 with around 20 VM's. I have to migrate it to another server which runs HyperV Server 2012 R2. I know that the export/import will not work in this case.

The two servers are 100% identical. I would like to do it safe, so I thought I will add a few disks to the 2008 R2 host, turn off the VMs and COPY all the VMs with all of the configuration files. From this point I won't start any VMs on the 2008 R2 host. After the copy is done, I would put these disks to the HyperV 2012 R2 server and import the VM's with "Register the virtual machine in-place" option. In case if I have problems after the import, I could start the VM's on the 2008 R2 host.

What do you think? Will it work?

Kind regards,

Dvijne

Windows 10 Pro running Hyper-V, Windows 10 Pro Virtual Switch up, network adaptor connected, now it wants proxy change settings to connect to internet, anyone knows what has to be done with settings and router, never used a proxy server directly.

Windows 10 Pro running Hyper-V, Windows 10 Pro  Virtual Switch up, network adaptor connected, now it wants proxy change settings to connect to internet, anyone knows what has to be done with settings and router, never used a proxy server directly.

I was "trying" Ethernet Realtech and Intel dual broadband adapter, restarted VM, a Kari tutorial said don't bridge anything to host OS, the switch will do it, invoking INTEL WI-FI adapter, its bridged, shared, and up in both instances.

The point is to get Windows 10 Pro Hyper-v VM connected to internet for windows updates and a application that can't run with Office 2013. 

The virtual switch was active, up, and I did not have network adapter selected to named new virtual switch, i restarted router, and VM a few times.  I need to know what proxy servers settings to use, I can see default gateway, and its own local IP.

Can anyone speak to proxy settings for a virtual switch and likely the adapter, the trouble shoot connections keeps coming back with change proxy settings.  It seems like I'm very close to getting this beast to work.  I've been fighting with it and reading and researching it for a couple days.
