I'm running out of room on my Server running Hyper-V, but I'm thinking of adding 16 900GB drives and I'm curious if this will be supported in Hyper-V.
Please help....

migrate xp-mode vhd from win7 -> win8
I have som programs only running on XP, and installed on a XP Mode.vhd running on Windows 7.
I have been able to move the vhd to Windows 8 and Hyper-V. BUT:
The license needs to be reactivated. Due to some problems vith addons I tried to mak phone-activation. Myt MS suggests that the copy is eventually pirated. I think its due to the fact that XP-mode is OEM, and I know no way to just change to a valid XP Pro license.
It is extremly many difficulties to bring old programs along:
- vhd splitted on 2 files, needs to be combined
- XPMUsers password - needs to be remembered/removed
- Virtual PC addons to be removed
- New integration addons (can't be installed if previous addons not removed)
- impossible reactivation
- impossible to upgrade OS to Win pro (no oem)
:(

Hyper-v with virtual machine manager.
Hi Guys!
I hope all is well. Can you guys help me on this:
What version of Standalone Hyper V 2012 comes with hyper-v with virtual machine manager.- to covert physical servers to HyperV machines?
And where can I find pricing?
Also: If our current Windows 2008 Server is on a physical machine- if we convert it to a HyperV machine will the server 2008 moan about licensing? As the Hardware will change?
Warm Regards

2 to 4 virtual CPU update for all guests on all Windows 2008 R2 hosts
Hello
I would like to update virtual CPU's from 2 to 4 for 900 guests across 12 hosts. I’m guessing I will have to do this via a powershell command. As I cant edit multiple guests in Hyper-V or SCVMM 2008. Would anyone be able to point me in the direction of the powershell commands I should use for this task?

Linux and memory allocation?
Hi
we have a RHEL-5.7 VM on y hyper-v cluster with LIS-3.4 tools installed. But we have problems with the memory allocation. The vm has a static memory with 12GB but every time the memory is used over nearly 5GB the vm begins to swapping. This is not what we want, the vm should use all physical installed 12GB. On the node where the vm is running are only 40% of physical memory is in use, so that the hyper-v can give the vm 12GB without any problems, but he doesn´t do that? And the question is why???
Could it be the reason that the "memory priority" has a normal value from 5000? What does it mean?
Should we increase that to the highest value of 10000?
Any hints are welcome, so that the vm can use the full allocated physical memory of 12GB!!!
Best regards

Virtual Machine Connection stuck on Connecting
I have WIn2008 R2 SP1.
When I click on "Connect" in the Hyper-V Management console, the VMC window appears and says "Connecting" and then nothing for about 10 minutes and then says cannot connect. This is happening to all my VMs.
I can successfully connect to the VMs via RDP.
This used to be working on this server but has now stopped. I am not aware of doing anything to Hyper-V so I don't know why this has started to happen.
I have double checked the VM additions and they are up to date.
Looking through the various Hyper-V event logs doesn't give a clue. I looked at 2 similar issues posted here but that didn't help.
The preview image displays fine.
I tried the suggestion in the last post to this thread, but no change: http://social.technet.microsoft.com/Forums/en-US/winserverhyperv/thread/55689ffb-da14-4649-9643-48fdecce4ff1.
The host file issue reported here is not a problem for me: http://social.technet.microsoft.com/Forums/en-US/winserverhyperv/thread/11fe9862-93ac-47a1-a9ae-a00f558b6e51/.
What next?
RDP is not always possible, e.g. when needing to use a VPN connection from the VM, so console access is a must have.

What version of OpenGL is supported on Server 2012 Hyper-V VMs? Can it please support 1.5?
Hi
Our application is being updated from supporting version 1.0 of OpenGL to version 1.5. Many video cards today support 4.2, so PM believes 1.5 is a safe choice, as it is from 2003.
As usual though, the test team's needs are not taken under advisement, as Hyper-V Server 2008 R2 SP1 only supports OpenGL 1.1.
We have a Dell R710 Server and given its shape and power supply, can't add in an PCIEx16 card. Dropping $15,000 on a QuadroPlex might work, if 2012 supports OpenGL 1.5, with or without RemoteFX. I ain't getting the money until I can prove it works.
Can anyone tell me?
We are using an exe from this site to test
http://www.realtech-vr.com/glview/download.php
use at your own risk, it is not my exe.
I am so done with the days of people thinking testers can test with a production machine, or in some dusty lab by installing an os every day.
Thanks!

Application licensing
Hi,
I have a application from "manhattan" that uses a license key for activation, this is keyed to the computers MAC address, Bios serial number and computer name, thus when these change I have to contact the vendor for a new key.
My questions are:
1. when a vm is rebooted will the mac or bios serial number change ?
2. when a vm is moved to another host will the mac or bios serial number change ?
Thanks for any answers.

hyper-v port acl and oid
When I set port acl to block the network traffic on VM , I am not seeinf any OIDs passing through the filter switch extension.
How is Port ACL information communicated to the miniport edge of the virtual switch?
I understand Port ACL is noly for filtering ip and mac addresses.
I want to filter protocol type or port number , I have to write WFP callout driver , right?
Thanks,

Sudden networking problem with VM
This is very odd and is driving me nuts!
We have a Windows Server 2012 with Hyper-V enabled. I have about 8 VMs with different OSs. As of about 6 months ago I've turned off all the VMs except two. One is a Windows 7 VM and the other a Windows 8. Something must have happened over the weekend because I'm unable to remote into the Win8 VM. I am able to bring it up in the Hyper-V Manager and log on to it. But that's about it.
It shows me that it does have Internet connectivity but I'm unable to browse to any site. Pinging the VM (using it's static IP address) results in timeouts. I restarted the VM countless times. I've removed the NIC in Hyper-V Manager and re-installed it, etc. Nothing seems to work. All along I am able to remote into my Win 2012 Server as well as into the Windows7 VM.
Any help would be greatly appreciated.

Hyper-v 3.0 replicated server - specify location of replicated VHD drives?
Hi all,
I have two identical servers with lots of quick storage (direct attached storage, however, not a SAN, NAS etc.), both with Server 2012/hyper-v 3.0 installed. I'm hosting an SQL server VM on server A (source) and I want the replication to to go to server B (target).
However, on server B, I'd like to be able to define the volumes where the replicated VHDs reside. The virtual server will be a SQL server, so there's a data partition, log file partition, etc. which I'd like to have mapped identically on server B. No one volume has the capacity to store the equivalent data of the combined data set of server A.
Is this possible at all?
Thanks in advance.

Remove-VmMigrationNetwork
Okay, I'm stumped. I have tried every combination of formats I can think of, but I cannot seem to find the proper string to remove a network from use by live migration. Maybe I'm trying to use the wrong cmdlet, but the description of Remove-VmMigrationNetwork seems to be what I am looking for -"The Remove-VMMigrationNetwork cmdlet removes a network from use with migration." I have tried from a host within a cluster. I have tried it from a remote host that I used to build the cluster with remote commands. I have tried wild cards and /24 notation (which results in a syntax error). I tied specifying a cluster name, a single host name, and all the host names in the cluster. And on and on.
The primary error I end up with is this (executed from one of the cluster nodes):
Remove-VMMigrationNetwork : Failed to modify service settings.
Cluster migration network tags cannot be modified. Please ensure you are not trying to add or remove a cluster
migration network for '192.168.16.22/32' : One or more arguments are invalid (0x80070057).
A parameter that is not valid was passed to the operation.

What is strange is that I am using a Remove command and the error message asks me to ensure I am not trying to remove.

Hyper -V Platform not installing from a Windows 8 Pro upgrade
Hi, I recently purchased Lenovo IdeaPad Yoga 13 which came with Windows 8. I upgraded to Windows 8 Pro and it's now activated.
I tried installing Hyper -V Platform because I'm working on a Windows Phone 8 app and currently don't have a WP8 phone. When I try to debug the app I get Hyper -V isn't installed.
So, I went through the BIOS to first enable virtualization hardware acceleration and then I went into Windows Programs Add new features and components and checked the box for Hyper -V
However I get the following error
"Windows couldn't complete the requested changes.
The component store has been corrupted
Error Code: 0x80073712"
I'm not sure where to go from here. I try it again I get the same error. I can't find an external URL to download and install and I have double check my activation of windows since I had updated it that day and everything seems to be in check,
just no luck with this install.
thanks,

Server 2012 Hyper-V no SCSI controller support
I would like to know if there is any solution in the world that would allow SCSI controller on windows XP 32bit VM using the new Hyper-V in Server 2012. I know that MS does not want us to boot off SCSI, which has been argued time and time again. But I
also want to have more then 3 drives ( not including the Optical ) to use in the VM. Its not about size, its about the available volumes to the machine. In VMware, which is the product they are attempting to compete with this is not even a contention on the
paid for or free versions. The true purpose of virtualization is hardware consolidation and usage/testing of various environments prior to implementation especial legacy support OS's. Can anyone tell me if there is a workaround or solution so that I can get
the VM to recognize more then 4 VHD's simotaniously. Does anyone else feel my pain in trying to rollout Server 2012 as a prouduction solution?

RAID10 - Sector Size error when creating or attaching VHD
Hello everyone,
Some of you may remember my thread I started recently about our performance issues with RAID5. I am in the process of rebuilding our array using RAID10 for better performance and I've hit a roadblock and need some assistance. I have searched everything the internet has to offer on this subject and nothing seems to be working.
After I copied all of our VHDs off to another storage location, I blew away the old RAID5 array and rebuilt the array using the following settings:
RAID10
4x2TB WD RE4 Disks
64K Stripe size
WriteThru
When I got into Server 08 R2 - Disk Management I had to initialize the disk and I did so as a GPT disk so I could use all 4TB of usable space that my array gave me. I formatted it using default NTFS settings. When I copied one of my VHDs back to the disk and attempted to create a VM attaching the VHD as the disk, I was greeted with the dreaded "The sector size of the physical disk is not supported". Everything I have found on the internet suggests that my problem is I have 4k drives, and 512 is the sweetspot... my problem with that is my drives are 512! I also read that I should convert the disk to dynamic in Windows, I tried that as well, and recreating the volume with just about every option for allocation size possible with similar results. Looking at my array settings in the web management utility shows that the block size is indeed 512.
I can't understand why I'm having this issue, I just Rebuilt the array again and I'm currently doing a full init instead of a fast init to see if that has an effect but I don't expect it to. I need you once again resident Hyper-V experts, please help me.

Removed Hyper -V role from Server 2008R2
We have a sever that came with the Hyper-V role installed......we did not need this so we uninstalled it.....however, there must be some remanants left over. On the nightly backup, we are getting a vss snapshot warning - File C:\windows\system32\drivers\vmswitch.sys is not present on the snapshot........I think this is because there is some remant in the registry which is pointing to this file (which is no longer there).......how can I fix this?
Thank you
