I have a couple of vhdx files on a 2012 RC host.
One had deduplication run in the guest which cut down the used space from 250 gb to 125 gb. Compacting it ends in 3 seconds and it doesn't shrink at all, stays at 275 gb.
Another is just a standard vhdx from another guest that has 30 gb of used space, but the vhdx is 39gb. Compacting also ends immediately with no shrink.
Is compacting broken in rc?
After I've installed Hyper-V role system boot time rose from about 1 minute to about 10 minutes.
I have i7-3930k CPU and Intel DX79TO motherboard with latest BIOS installed.
I'm on Windows Server 2012 Standard.
Hello Im unable to migrate a VM from 2008 standard to 2008r2 standard Host
Ive tried this from Hyper-v manager and through scvmm, Is there an update I need to apply?
Error unable to migrate or clone the virtual machine software ( 6.1.7601.17514 does not match the version the virtual machines virtaulization software on the source (6.0.6002.18005)
Thanks

I have installed Windows 2012 Hyper-V Server. The guest VM consists of a couple W2012 Servers simulating a Domain. The hardware is a Intel Intel S1200BTLR board (BIOS is up to date), a Xeon E3 1220Lv2 and a Intel I350 dualport NIC. The I350 support SR-IOV as well as the current driver (V. 17.4) does. The virtual switch is configured to support SR-IOV as well as the NIC in the VMs. However Network Status always shows:
Degraded (SR-IOV not operational)
VMQs are working. The command "(Get-VMHost).IovSupportReasons gives:
SR-IOV cannot be sued on this system as the PCI Express hardware does not support Access Control Services (ACS) at any root port. Contact your vendor for further information.
I really would like to get SR-IOV up and running. Does anybody know if the reason given is the "true" reason? Do I have to configure something (VT-x and VT-d is enabled)?
I also would like to know if someone has gotten SR-IOV successfull running on stock hardware (like different Intel Server Board, for example one for the E5 processors with integrated i350 NIC).
I tried Intels Website to find some more informations regarding "this product is supported" or "this product will be support with the next driver version. But all it gives is some general information about SR-IOV and whitepapers.
I am currently running Hyper-V on 2 identical hosts. I would like to set them up so that if a VM or Host fails then it would automatically start on the other available host. I had a question on where to store the VHDs for the VMs and how to access them.
They are currently on a LUN which I have mapped via iSCSI to "D" on Host1. Would I be better off converting it to a CSV and storing/sharing the VHD files from there?
Hey Guys,
Im not even sure if this is possible, but I've been searching and cannot find an answer.
I have a Linux backup server that is hosting an NFS shared drive. I can connect to it great with VMware and my vm's can see the drive fine.
How do you mount an NFS share to a HyperV host?
Thanks
Hi everyone,
I've been testing WS2012 for some time but recently I've been running some tests in the lab with Linux. I'm shocked no one else has reported this error but then I doubt that many people run large Linux VM's on Hyper-V.
If I assign 4 GB memory to a VM it installs and runs CentOS perfectly with very impressive performance.
However, if I assign more than around 6 GB of Memory (8 GB completely breaks it) the CentOS installer does not even load and shows the following message:
PANIC: Early exception 06 rip 10:ffffffff81c451bb error 0 cr2 0
I would like to add that this also happens on a fully installed VM CentOS 6.3 with IC 3.4. Screenshot attached. Hopefully this can be resolved by an update... :-)
Hi!
Hyper-V on 2012.
I've got a Ubuntu, 12.10, server installation which i try to add some storage to. I've created 64GB harddrive (VHDX) as the 1st drive. And then a 2nd drive 4TB (VHDX). Thin.prov on both.
Creating and formating: Using gdisk, parted or gparted (livecd) on ubuntu I'm not able to partition, GPT, and initiate a filesystem on the the large VHDX.
Is there a problem with Hyper-V 2012 and drives (VHDX) >2TB when used by guests?
There is a tool last updated in 2011 that claims to work with Windows Server 2008 R2, that will convert a VMWare VM to Hyper-V. If I had a Windows Server 2008 R2 machine with Hyper-V on it, I suppose I could use that.
I'm a home user with Windows 8 Pro (64 bit) and I'm using Client Hyper-V very well, but I have some VMWare machines I'd love to convert. I can't even run VMWare on Win 8 very well, because the hypervisor in Hyper-V is detected by the VMWare workstation and VMWare player installers. There are some boot.ini hacks that claim to disable HyperV Hypervisor at boot time, which allow you to install VMWare Player or Workstation and then reboot and start/stop some services to toggle between the two. This is not a very nice solution either.
Other than getting a Win2008R2 Machine set up just for the conversion, or setting up System Center just for one conversion (both of which seem absurd to me) is there any way anyone can see to do this JUST on my Win8 machine at home? I am aware that there are tools built into the giant monster that is System Center 2012, and I am aware that there are third-party tools that will work on Windows 2008 R2 with its Hyper-V, but I haven't found any way on Win8Pro itself, with anything that will run on Win8Pro.

I was running 4VMs on a single host - all 2008 R2 OS. I upgraded my host to 2012, and now all of my VMs freeze while trying to shutdown, or restart. I've figured out it has to be the network drivers - as if I change the VNIC to none, there are no problems restarting or shutting down. I've tried the stock drivers, new drivers, etc - nothing seems to work now. Why was this working just fine in 2008R2 and now it's not compatible in 2012??
Anyone have some advice for me besides spending more money on a network card?
Hi everyone,
I am quite new to windows server.
I have only one server and I need to install sharepoint 2013 ad office web apps into it. but it cant be done on one server.
Could you help me if virtualization would help me?
Do you know some articles where someone solves similar problem?
Thank you for your replies.
I've just acquired a Dell Optiplex 755 (Small Form Factor) with the following specs:
Core 2 Duo @ 3GHz
2GB RAM (8GB max)
160GB hard drive
It's Core 2 Duo processor supports VT according to the technical schematics on the Intel website. The PC is capable of a maximum of 8GB. Because there is only enough space for one hard drive in this system, do you have any suggestions on how I could optimize the performance of this system? Purchase a solid state drive perhaps? Also, because I won't be able to run 64-bit VMs inside Hyper-V, in therms of performance would I be able to get by with a lab set up that only uses 32-bit VMs? I'm currently acquiring equipment needed to help me study for the MCSA 2008 certification but unfortunately on a tight budget. Thanks!
When i try to create a new V-Machine i get this error. im not able to do it. i tryied with Admin user also but same problem. please help..

Hi,
Once I configure my Windows 8 Hyper-V External Virtual Network Switch to use my laptop Wireless adapter, all VMs has External NIC can access internet, however the physical Windows 8 host lost the internet connection, although I checked "Allow management operating system to share this network adapter",
What can be the problem?
I evicted a node from an existing cluster, no issues. After several reboots c:\clusterstorage is still on the c:\ drive. What steps do i need to take to remove the folder?
Any assistance would be helpful.
Hey,
I got a question. I have a Windows 8 laptop. I wanted to play around w/ Domain Controllers, etc, so I installed a VM of Windows Server 2012. I installed the Domain Controller services on the VM.
Now, I'd like the host to be able to join the domain. Obviously, the VM must be running for the host to join the domain. Is there a way to start up the VM automatically when the host powers up, so that the host can join the domain?
What's the best way to do this?
I'm trying to get a handle on NIC Teaming. After reading several white papers and looking at several blog entries, my head has too many questions floating around in it.
My Setup:
4 Windows 2012 Hosts in a Cluster All running Hyper-V
Management NIC
Redundant Channel NIC
4 other NICs to use for the Hyper-V Guests.
Guest VMs are:
AD DCs (DNS, WINS, DHCP, AV Server, Print Spooler)
File Server
SQL 2008 R2 Production Server
SQL 2008 R2 Post-Production Server
SQL 2000 Server
IIS 8 Server
A Few Win2012 Member Servers
TeamFoundationStudio Server (SQL, IIS, Sharepoint)
RemoteDesktop Server
My Networking goals are to increase the bandwidth between the SQL 2008 R2 Production Server, SQL 2000 Server and IIS 8 Server. And to have the IIS8 Server pump out more Data to Clients.
Reading through it looks like I have 3 options:
NIC Teaming on Hyper-V Host
Address Hash
Hyper-V Port
NIC Teaming within the VM Guest
Seems like the Best is to have NICs connected to the Hyper-V Virtual Switch with SR-IOV and then do NIC Teaming in a Windows 2012 Guest OS.
Though some of my Guest OSes are Windows2003 R2 (for the SQL2000) and Windows 2008 R2 for SQL 2008 R2.
What are my best options to help get better bandwidth ? Is having all of them on the same Virtual Switch good enough and then Team the IIS8 Server within the Guest?
Was thinking of having 2 of the 4 NICs be Teamed at the Host, and the other two Available to the Hyper-V Switch and be able to NIC Team within the VMs?
Suggestions?
Hello,
I currently have 9VMS running on Hyper-v 2012. Sitting on RAID-10 (10,000RPM) drives. (6-total drives @ 10,000 RPM: RAID-10).
If I turn on Bitlocker is there going to be hit? Is it going to be noticable?
VMs are running light SQL servers.
Also do people recommend ReFS? I will be using hyper-v replica, does ReFS work?
Thanks,
Keer
Hi all,
I've been reading up about VHDX's, and one of the new features is how custom metadata can be kept (inside?) the VHDX file. Such as OS version, patch levels, applications installed etc.
My question is... what tool/powershell/method do you use to insert that data? I can't find a blog post or how to anywhere.

The backup operation that started at '2012-11-16T02:00:07.911699300Z' has failed with following error code '0x80780049' (None of the items included in backup were backed up.). Please review the event details for a solution, and then rerun the backup operation once the issue is resolved.
We are getting the above error when trying to backup the Virtual server
We used disktvhd to convert a windows 2003 machine to a VHD, we then converted the VHD to a VHDX and now we are trying to backup the virtual server (running on the server) to a USB drive, we it keeps failing.
We installed the integration tools, do we have to add anything else to use Windows Backup?
