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?

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.

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.

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

We will be preparing a plan to transition from a 2008 R2 Cluster to a 2012 new Cluster.  One area that is still not totally clear is the best method for Nic Teaming.

In the existing 2008 R2 Cluster we have 4 Dell R610 server's using multiple nic-teams.  These are done at the Driver level using the Broadcom Driver suite and also the Intel drivers.  That said, is it recommended in the 2012 environment we perform them with the built in Windows Teaming?  Should we no longer perform the teaming within the drivers?  Is performance using the Windows teaming comparable?

I like the concept of moving this from the drivers to the built in teaming, this seems like a better approach however I would like some input on this. Thanks

Hi,

What is the average time you would expect a VM to move from one host to another using live migration? We are seeing times of between 20-40 seconds.  So if we have about 60 VM's it is taking a long time to put a host into maintenance mode as Hyper-V does one at a time.

What speeds to you see?

We are using Cisco UCS Blades in a Flexpod so would expect it to be fairly quick!

I expanded the VHD but I did not have any snapshots of the VHD. The expansion went smoothly, the machine was working properly. Now all of a sudden the machine is saying that the VHD is corrupt or unreadable. I have tried to use the vhdtool.exe but I don't have any snapshots to repair it from. I have tried everything I believe, and rebuilding the VHD would be last case scenario.

I'd like some opinions on running multiple virtual machines on a single host and how much performance can be affected.

Our servers run a single Xeon E3-1270 processor with 32GB memory. 4 Western Digital RE4 1TB drives are in RAID 10 on an Adaptec 6405 card with module for cache protection. There are two onboard NIC's, one dual-port NIC and one single-port NIC via PCI Express slots. I plan to team the onboard to access the host server. The dual-port NIC's I plan to team for the VM's, and the single port NIC I plan to connect to a different switch which connects our storage devices using iSCSI to seperate traffic.

The physical server OS will not run anything other than Hyper-V role. I plan on having 3 virtual machines on this server.

1 VM will run Active Directory and DNS (4GB memory allocated)

1 VM will run Sage accounting (16GB memory allocated)

1 VM will run Print and WSUS (4GB memory allocated)

That leaves 8GB memory for the host or if I need to spawn up another virtual machine.

On the other server, same specs.

1 VM will run AD/DNS replicated (4gb memory)

1 VM will run engineering software (database driven) (16gb memory)

1 VM will run Symantec Endpoint Protection and Ghost Server (4GB memory)

We have 38 users total. 12 of which use Sage concurrently throughout the day. We have 8 network printers.

Given the specs on the server, is there any bottlenecks you can think of that would hinder performance running 3 VMs on each host.

We purchased a new Powervault PV3260 with 30 2TB Drives.

Say for instance in a Typical Exchange Environment you would have 5 Drives, One for the OS, One for Mailbox Data, One for Log Data, one for Recovery and  5th to Backup to.

Similar for SQL Server, OS Drive, Data Drive, Log Drive and Backup Drive. 

With all of the servers being in a Virtual Environment and that they are all connected to the Powervault PV3260, each Virtual Disk is part of the same 30 disk Disk Pool.  Does it make sense anymore to separate out the different disks for the Servers if they are all spread among the disks in the PV Disk Pool?  I could see Maybe having the OS Drive reside on a Virtual Disk with other VM OS Images, and having the Data Disks be large enough to handle the Data, Logs, backup and make it a Pass through disk to the vm?

Thanks,

Hi, 

i am using Windows Server 2012 (Standard, English) as Hyper-V host. I do have a single vSwitch configured as "internal" network. 

If I configure RRAS as a NAT router (on the host) I  sporadically loose my network connection to the host. It works for a few minutes, sometimes for an hour, and without any obvious cause I loose my network connection/RDP session. 

I used that exact configuration for years in WS 2008 R2. I have no idea, what the root of the problem is. 

Thanks for your help in advance,

Thorsten

Hi,

I have windows server 2003 R2 on my virtual machine. It's registered in ktu.local domain.

When I try to log on using my domain account it takes forever to load the system up. Also I'm unable to install any software that requires ktu.local domain account. I get the following error message:

Setup could not find the domain 'KTU' for the business Connector Proxy account.

It seems as logging and checking account  password exceeds time limits.

How could i solve this?

The problem is, my virtual machine lost connection to domain and not remember local administrator password for access to computer.

Need access to virtual machine for recconect to domain.

Ideas?

Thanks for solved the problem,

Hey Peeps,

I'm rather new to Hyper-V and not sure how to correctly configure the networking between my management OS and guest OS. As the management OS, I'm using Windows 8 Pro and installed Windows XP SP3 on the Hyper-V machine. I've also setup my network as an Internal Network so that I can achieve copying files to and from the guest and management OSs. After configuring it and starting the VM, I was able to access the VM from my host OS but was unable to see the host machine from the VM.

Now that I have restarted my computer, I'm not able to access the host OS from within the VM and vice versa. What is the correct way of setting up the networking between my host OS and guest OS? I have a different workgroup (not using the standard Windows-assigned workgroup) and assigned this workgroup to both systems.

I'm mainly using the Hyper-V machine to test my software applications for compatibility and bugs and might use the Hyper-V machine in the future for SQL Server failover simulations to ensure that my applications can continue to run even with power outtages on some of the servers. I'm not a networking guy so please tell me step-by-step what I need to do and how to configure the two systems so that they can communicate with each other at any given time. I don't want the Hyper-V machine to access the Internet or use connection sharing as its just a test environment.

My apologies if I posted this question in duplicate, but the other thread's I've read automatically assumes that you know how to change IP addresses and so forth - things I do not have experience in.

Hi.

I have a set up a WinServer 2012 environment to test VDI.  This deployment will be for personal virtual desktops which are assigned to specific users, not pooled VM's.

I have a Hyper-V server "Win2012-HyperV", where there is one Virtual Machine created. This VM is named "vmRob.mydomain.local".  I installed Windows 7, joined the virtual PC to the domain with the computer name "vmRob.mydomain.local". 

I also have a Broker server set up, "Win2012-Broker", with all the requisite Server Roles (I think).
I created a virtual machine "collection", and added "vmRob.mydomain.local" to it. I assigned the VM to a domain user "rsmith".

All servers are added to my domain. I can go to the Hyper-V server and start the VM.

Now, I go to another PC, and run mstsc.exe (Remote Desktop Connection). I want to connect to "vmRob", not the Broker server itself. In RDC, I specify the computer "Broker2012" and the user name "mydomain\rsmith". When RDC connects, it displays the Broker's desktop -- the user "rsmith" is not being "redirected" towards the Virtual Machine.

The Broker should start the VM "vmRob" on the Hyper-V server and display that back to the RDC client. I had it working in WinServer 2008 R2, but I am missing something in 2012...  I should note that I do not have the Session Host role installed -- I have been led to believe that it is not required, unless I am doing pooled VM's.

Any suggestions?
Thanks.

We have recently setup a new Windows 2008 R2 Standard server with the Hyper-V role. We have a 8 drives connected to the onboard SAS all of which are offline in disk management. They are assigned as physical disks to one VM running Ubuntu. Everything has been running fine until we added a SAS HBA to the system. This is needed for our tape drive to attach to this machine. When Windows boots, the card and tape drive is seen no problem. The disks are still listed in disk management in their offline state. The problem is, we cannot start the VM anymore because the option to use the physical disk is grayed out. On the virtual SCSI controller that is attached to the VM, it shows the disks, but it says "in use". If you remove the virtual SCSI controller and add a new one, the physical disk option is grayed out. Anyone have any ideas on this? Thanks in advance.

I just installed a new Dell Poweredge R620 with Windows Server 2012.  However, I don't know anything about the Hyper-V role but I am excited to learn about it since I want to depoy several virtual servers in the upcoming year.  I was wandering if anyone had any good book recomendations for "Hyper V with Windows Server 2012?"  I want a good comprehensive book so that I can learn Hyper-V inside and out.

Thanks

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?

HI,

We migrated a SBS 2k3 to a virtual machine (host is windows 2k8 sp2 with Hyper-v) using disk2vhd.

We checked the update hal checkmark, but now we are running into a problem. The disk2vhd placed a virtual server hal in the VHD. As soon as we try to insert the integration services disk it keeps saying it has to update the hal and needs a reboot.

We say ok, it says it is updateing the Hal, it reboots and then comes again with the same message that it needs to update the hal. So we are in a loop.

Anyone familiar with this problem?

I was able to recreate the problem with a windows xp machine too.

Best regards,

Henry
