Unabel to setup remote desktop access to isolated HyperV lab
Hey Guys,
I have an isolated HyperV lab made of 5 VMs which are in fact copies of live production VMs.
The lab is made of 4 SharePoint VMs + 1 DC and is working fine on its own. All VMs are connected to the same private HyperV network. Because these VMs are SAN copies of live machines, they can never communicate with the company LAN.
I now need to provide RDP access to the lab. We've first tried to use the HyperV manager to connect to the lab, which works fine, but is not comfortbale to use and only allow on connection at the time per VM.
So the idea is now to setup the host as a Terminal Server, the developpers can then RDP to the host and hop with a 2nd RDP to any VM in the lab.
My idea is to implement the following setup :
The Remote Desktop Services have been installed and configured, but I have the following issue: I cannot RDP to the host as soon as I enable the virtual NIC connected to the internal hyperv network. It's like of the traffic was not routed in the corrected direction. When that NIC connected to the internal hyper network is enabled, I cannot ping any machine from production and I must connect through iLO to manage the host (iLO = HP's console). As soon as I disable the NIC connected to the internal hyper network everything works fine again (except that I cannot of course reach my lab).
I've tried to play a bit with the order of the NIC in the avanced settings, but this didn't help.
What am I missing here ?
Thanks in advance for your help and have a nice day

Virtual Machine Additions Issue
Hi guys,
A couple of day ago, my main server went down. It happened to be the one running Virtual Server & 3 VM's on it. I decided this was as good a time as any to move from 2003 to 2008, & from VS to HV.
All seemed to be going well, however I've now realised I still have VM Additions installed from VS, and they won't uninstall under HV.
Is there any way to force them to uninstall or uninstall them manually, without having to build another server & install VS again? Could they maybe be uninstalled under Virtual PC instead?
Hope you can help!
Regards,
Graham

application aware snapshot fails on oracle server
Hyper-V failed to generate VSS snapshot set for virtual machine DBSERVER: Exception occurred. (0x80020009). VSS snapshot set generation can fail if backup operation is in progress
I see the error above on Hyper-V host server.
On the DB server i see two VSS events

Licensing question regarding Server 2008 R2 Datacenter and hosted Windows 7 Virtual Machines with MS Office
I need some clarification on some enterprise licensing regarding Server 2008 R2 Datacenter with hosted virtual machines, so here's my scenario:
I have a server running Windows Server 2008 R2 Datacenter edition with 22 virtual machines hosted using Hyper-V. All of these machines are using Windows 7 32-bit with Microsoft Office 2010.
I've read through my licensing paperwork and, as I understand it, any hosted operating systems running in VM's under the Datacenter license don't need to be licensed, however I haven't been able to find anything regarding how I need to license Office as I don't imagine the Datacenter license is covering the Office instances.
Can anyone provide some clarification for the proper way to go about licensing this server?

Move virtual machine storage corrupting disks
Hi,
I have now had 2 VMs corrupted when using Move Virtual Machine Storage.
After the move has completed the server fails with a BSOD and on reboot gives the error 'A disk read error occurred. Press ctrl alt delete to restart'
This event is logged on the HyperV host:
Log Name: System
Source: Virtual Disk Service
Date: 1/08/2013 7:45:13 AM
Event ID: 9
Task Category: None
Level: Error
Keywords: Classic
User: N/A
Computer: HPV10
Description:
Unexpected provider failure. Restarting the service may fix the problem. Error code:80004005@02000014
I have not been able to recover the disk - I made a thread about this after the 1st corruption -
Since then I have rebooted the cluster (+ windows updates) and taken SAN snapshots before attempting to move another VM.
I am now very nervous about using this feature again. What can I do to identify the cause of these issues?

Hyper-V Replica: decrease interval between recovery points
I'm trying to configure multiple recovery points with Hyper-V Replica (2012).
The problem is that the preconfigured interval between the points is to high for me (1 hour). I would like to have a time gap of 12 hours between each recovery point.
Is this possible?

Back up options for Hyper-V Virtual Servers That will allow backup while running with dynamically expanding disks?
I have some virtual servers that are dynamically expanding disks. I have read that to utilize a backup with VSS the VM must be shut down because of this. My employers are concerned with this method. They are stating that the VM's are "hacked" to work as they have them and that shutting them down is risky. Instead, They wish me to find a solution which can be:
- Run with the VM operating.
- Allow for restore of the VM (not rebuild).
I still feel the best way to do this is to shut them down and back them up. Am I wrong? Is there a better way and is what they are asking possible? Would backing up the VM from the inside be worth doing?
Thank you for your time and assistance.

Possible to live migrate a VM from stand alone Hyper-V 2012 to a Hyper-V 2012 cluster?
I have a VM that is on a stand alone Hyper-V Server 2012. I just built a new cluster consisting of two Hyper-V Server 2012 connected to a SAN. Can I live migrate my VM from the stand alone machine to the cluster connected to the SAN?
The hyper-v virtual switch is the same on all three nodes.

is getting to WMI of VM possible via host?
i need to query hosted VMs for some OS parameters. i can query for FQDN and/or IP of the machine but as they are in numerous VLANs and are secured with FW and are in several domains... it will not be possible to make it as for normal server.
as Integration Services gives some kind of bridge between host and guest i was thinking that maybe there is some way to query internal OS of VM somehow through it?
same question in reverse: how would you automatize some administrative tasks on VMs on hosted environment?
...of course i know it's against security blablabla ... anyway maybe there is some backdoor giving access to VMs q:

All VM's locked up in Server 2012 Cluster!
Hi,
About 2 hours ago this evening, we lost communication to all 20 VM's on a 8 Node Cluster and they took 25 minutes to recover! Fibre Channel shared storage is being used throughout the cluster through 2 redundant routes from each node. The host OS was still working fine. I appreciate this points to the storage going down but I really don't think it had, there are no errors on either FC switch and no error on either storage device. We are using Server 2012 on HP DL360's.
The Get-ClusterLog returns this error at the time they all went down:
00000370.000010d8::2013/04/14-20:12:25.115 ERR [RHS] RhsCall::DeadlockMonitor: Call TERMINATERESOURCE timed out by 6 milliseconds for resource 'SCVMM VM1'.00000370.000010d8::2013/04/14-20:12:25.115 INFO [RHS] Enabling RHS termination watchdog with timeout 1200000 and recovery action 3.

Hyper-V & VLANs
I was reading this article about Hyper-V and vLANs: http://blogs.msdn.com/b/adamfazio/archive/2008/11/14/understanding-hyper-v-vlans.aspx
From my understanding if I am passing through my physical nic for example 3 vLANs (1,2,3), and I need to configure (for example) a few VMs with 3 NICs on all of those networks, I could either:
A. Create 3 virtual external switches (assuming the VMs need to communicate with the outside), each defined with a vLAN ID pertaining to the appropriate network. Then I would give each VM a NIC that's mapped to each one of the virtual networks
B. Create a single virtual external switch, single network, but define the VLAN ID on each VM's individual NIC
Is one solution better than the other? Does it depend on the use case? Is there any documentation explaining this any better?
Thanks,
Reuvy

Help with storage space volumes and HYPER-V
Help please,
Using Windows 8 Pro Hyper-v I created a VM and installed Windows Server 2012 R2 Essentials. I had attached two disks to the WSE VM that I then setup as a storage space within WSE. After a Windows 8 restart which crashed the WSE VM the two disks that I had attached to the WSE VM are now online to Windows 8 and I cannot get them offline to re-attach to the WSE VM. The WSE VM refuses to restart without them. In Disk Management it says they are both part of a Storage pool, but any attempt to take them offline is ignored.
How can I get out of this mess?

Hyper-V Management API and Docs
I have been looking for the Hyper-V Management APIs or documentation, so far unsuccessfully. I was under the impression the management API and docs might be available for the first public beta. I found these .NET assemblies:
12/11/2007 06:32 AM 337,864 Microsoft.Virtualization.Client.dll
12/11/2007 06:32 AM 280,520 Microsoft.Virtualization.Client.Management.dll
12/11/2007 06:32 AM 145,352 Microsoft.Virtualization.Client.RdpClientAxHost.dll
12/11/2007 06:32 AM 124,872 Microsoft.Virtualization.Client.RdpClientInterop.dll

12/11/2007 06:32 AM 362,440 Microsoft.Virtualization.Client.VMBrowser.dll
12/11/2007 06:32 AM 546,760 Microsoft.Virtualization.Client.Wizards.dll
There are any official docs, or are we expected to use Sandcastle to extract the docs?
Note: I'm not looking for low-level Hypervisor APIs, but rather the APIs to create machines, VHDs, attach devices, power on/off, suspend, take snapshots, revert to snapshot, etc.
Any information welcome.
Thanks!
