Hi folks,
I am running a custom linux on my Hyper-V in Windows Server 2008 R2. I initially configured one disk(4GB) and then I added one more hard disk of higher capacity (8GB). Now I got two vhd files with different sizes.
If I want to create a new linux VM (with two hard disks as original), with an existing vhd file, which one can I use?
I tried the first one, but it is not working as expected.
Is there any other way to get a bootable vhd file for a linux VM with two hard disks?
Any tools to make it?
Thanks in advance,
Saleem
I have a VM with multiple VHDs. One of the VHDs must be moved to a different physical volume for performance reasons. What is the best approach to moving the one VHD, not the entire VM to a different physical volume after shutting the VM down? Move the VHD to the new volume and change the drive path? Or, in the VM settings REMOVE the drive then reattach from the new location after moving the VHD?
Thanks in advance!

We just set up a new 2012 R2 cluster and we are having troubles with live cloning. I have seen it work in our environment but usually it fails.
We get this error in our cluster events:
Cluster Shared Volume 'Volume8' ('Volume8') has entered a paused state because of '(c0000435)'. All I/O will temporarily be queued until a path to the volume is reestablished.
and the clone fails with:
Error (2916)
VMM is unable to complete the request. The connection to the agent ServerName was lost.
WinRM: URL: [http://ServerPath], Verb: [INVOKE], Method: [GetError], Resource: [http://schemas.microsoft.com/wbem/wsman/1/wmi/root/microsoft/bits/BitsClientJob?JobId={DC6D9530-26F1-4F95-A1AB-0197B1406F98}]

The storage is a Dell EqualLogic PS6500 and its connected to two S55 Force 10 48 port switches. The client side of the network is hooked to two Cisco 2960G 48 port switches.
I can't find any information on error c0000435. Has anyone head of this issue?
Hi I have a server with 2012 R2 and Hyper-V is installed. I have set my VM's up and everything on the server is working perfectly. I installed the hyper-v role on my Win 7 x64 machine and it will not connect to my server. I ended up calling in to microsoft and they have determined it's a bug. I really need a work around does anyone know of a work around?
Thanks,

Running a two node Hyper V cluster on Windows 2012. One of the nodes all the virtual machines stopped responding to network connections. Checking thru Hyper-V manager showed all nodes running correctly and no errors on the VMs.
Moving the VMs to the second node caused network issues to go away, all nodes working correctly. Moving a VM back to the first node caused its network to drop again. Rebooted first Hyper-V node and then moved VM back. Everything working.
No errors in the Hyper-V node or VM. VirtualNIC did not show any disconnects or errors. All very strange.
Servers are Dell 710 PowerEdge using Broadcom NetXtreme NICs.

Hi all,
I'm trying to create an External Virtual Switch for WiFi connection. If I create the switch, Hyper-V process the request then as soon as it finish the system blue screens.
I've look through the Hyper-V Event Viewer logs but cannot see any reference to successfully created or otherwise... The driver appears to be up to date.
I've upgraded to 8.1 from 8 a couple of months back, this is the first time I've tried to create a new Vitual Switch on 8.1..
Any ideas - I'm very stuck!!
Thanks,
Tim
Thank you for you time folks!
Hello Community,
I have a Hyper-V instance installed on my Windows 8.1 host, and I am finding that transfers using TSClient (shared drives from the host on connect) are extremely bottlenecked. I will get 30MB/s transfer rates via TSClient compared to ~300MB/s rates if I copy the same file over a network share.
I am wondering if this is a known issue and/or if I a overlooking something completely obvious. :)
Thank you for any assistance,
Michael
Hi, I have a 2 node Windows Server 2012R2 (GUI install) Hyper-V Failover Cluster. The guest OS'es (mostly 2008R2) run fine on both nodes, however when they are on one specific node, the WMIPRVSE.EXE process is using somewhere between 20 and 40% cpu inside that specific guest OS every about 3 seconds. I've been trying to investigate, but can't get my finger behind it yet.
This is one of the guests, where it was running on the 'good' node, then a live migration to the 'bad node' and then again live migration back to the good one. The process using the CPU is WMIPRVSE.EXE.
The cluster is using CSV disks, cluster validation is OK, only some warnings on VM's that are currently shutdown. It looks like the host talks to the Guest OS for some reason (performance / health / heartbeat or something?) which makes the load go high. Guest additions are up-to-date.
We also run VMM, I shut that down to make sure that isn't polling something for a reason, but that didn't help.
Hosts are exactly the same hardware, same patchlevel, same drivers. They have boot been rebooted to no avail either.Hello,
I have set up two Hyper-V 2012 R2 servers and set up VM replication. However, when I started the "Enable Replication..." Wizard for a VM, the wizard never asks me what replication interval to use. I have attached a screenshot for reference.
Why would this behavior occur? Also, is there a way to set replication interval using PowerShell?
Any insight you could provide would be most helpful.
Thanks!
My lab setup:
I have a windows 2012 Hyper-V parent on which I installed three windows 2012 VMs with default configurations. After the setup, everything was good and the VMS were able to access the internet and parent. I did not check communication between VMs though. This is my lab setup and followed instructions from a Microsoft certification guide for SQL server 2012.
Next I renamed machine one as DC, and made following configuration changes after a restart-
Next I renamed machine two as SQLA, and made following configuration changes after a restart-
Repeated above steps for SQLB with its ipv address set to 10.10.10.30
After the setup all looks good and I am able to join logon SQLA and SQLB as domain admin.
My issue:
I lost access to internet through the parent. Also from SQLA I cannot ping SQLB or vice versa.
I like to be able to access internet from the VMS while on a private domain. I also want to have the connectivity between the VMs.
Hi Team
I have installed Microsoft Hyper-V Server 2008 R2 in a stand alone server. This server is not on a Domain, but it is in a workgroup environment. I have enabled all the options available in theConfigure Remote Management option in the Server Configurationmenu in Hyper-V Server 2008 R2.
After that I have installed the Remote Server Administration Tools under Windows 7 PC(on a Workgroup) from where I intend to mange the Hyper-V Server 2008 R2. After installing the RSAT, I have enabled the Hyper-V Tools from the Turn Windows Features on or off. Now I have an option calledHyper-V Manager under Start --> All Programs --> Administrative Tools.I launch this Hyper-V Manager and trying to connect to the server by specifying the Hyper-V Server 2008 R2's IP Address. After waiting for a while, I am encountered with the following message "An error occurred while attempting to connect to server "192.168.1.xxx". Check that the Virtual Machine Management service is running and that you are authorized to connect to the server. You do not have the required permission to complete this task" and I am unable to connect to this Hyper-V Server 2008 R2.
When I am trying to connect to this server from Windows 7 PC where Hyper-V Manager is installed, I provide the administrator account of the Hyper-V Server 2008 R2 and the password.
Searching the net, I can't find any helpful assistance on this issue. Looking forward to hearing from some of the experts from MS Community. I also would be happy if you some one could post some procedure on creating the Virtual machine once I am successfully connected to the Hyper-V server as well.
Thanks in advance.

Hi ,
V host running Windows Server 2008 R2 and the VM running Windows 2K3 or Windows 2008 R2 are losing the network very often. The network adapter value get set "Configuration Error" and machine lose all connectivity .
If I re-add the network connection to the VM then it work fine .
Also if I install client OS like Win7 , XP then the VM network work fine and never show the "Configuration Error" in network adapter.
Any ideas what may be causing this issue? Is Win2k3.Win2k8R2 need any specific hotfix to resolve the issue ?
Thanks,
Suresh

Im setting up a lab at home to start testing my knowledge . I have a pretty power-full pc and is the one I used for 70-410/411 I have Hyper-V setup. Although on all the other certs I made 4 VMs from scratch on this one I wanted to crate a VHDX with an image of Win server 2012 and create 4 VMs that use a differential HDD so I didn't have to install the OS 4 times. But I ran in to a problem, on the lab I need to create a child and a tree within a forest, so on 1 vm I have the forest contoso.com and on the other 2 vms when I try to create the child domain or the tree i get the following error:
The operation failed because:
The security account manager (SAM) has determined that the security identifier (SID) for this computer is already
in use in the forest you want to join. This can happen when restoring an Active Directory Domain Controller with an improper backup. Reinstall the operating system on the local AD DC to obtain a new SID.
"The specified domain already exists."
I sysprep the parent hard drive re-created the vms and I got the same error.
If anyone have a suggestion please let me know, I guess Im going to have to create 4 new VMS and not do differential hard drive.
I installed a Hyper-V server core and a Win8 PC.
I found both of the machines have to join the AD in order to let the Win8 PC to run the management tools to manage the Hyper-V core. In compare with the ESXi, I can manage the server with a Win7 PC w/ vSphere Client installed.
Is there any way I can manage the Hyper-V Core without required to join the AD??
Hi:
Are there any specific BIOS settings for Hyper- V that we should take into account when reinstalling a server with Windows Server 2012 Std to virtualize 8 virtual machines with Windows Server 2008 R2? I detail more our problem if anyone can help with any other ideas :
We have a Hyper- V cluster of two nodes with two Dell Servers (PowerEdge R620) and a SAS SAN (PowerVault MD3200 with dual controller). The connection between the servers and the SAN is via two dedicated 6Gbps SAS HBA in each server (one HBA on each server to each of the controllers). Physical operating systems are Windows Server 2012 Std and virtual operating systemas are Windows Server 2008 R2 Std.
From the beginning we had performance problems with virtualized applications (proprietary databases). We assumed it was something related to the SAN or to the storage access. After many changes and testing we have ensured that the disk subsystem is not a problem, and performance has greatly improved, but some problems remain the same, and one of them especially.
Anyway, tired of trying , testing , configuring ... we have mounted the main application virtual server, where more marked is the problem, into an old server (almost 5 years) installed also with Windows Server 2012 Std, and surprise, the problem disappears. We repeated the procees in another outdated server, and again OK. Further tests are consistent, and the new hardware performance in processor and disk access are much worse than the current system, as expected.
The obvious conclusion is that there is some problem on the new servers, and in the two servers (since the virtual machine directly executed on both, without cluster and without SAN, exactly reproduces the problem ), which leads us to think of a problem with the physical operating system installation (both servers have the default Dell factory installation), BIOS parameterization, or some component firmware.
The specific problem is a process that runs locally on the application server, not using network communication, but using hundreds of thousands of sockets open from the server with himself. Spying the process with a sockets sniffer we can see how the socket opening speed are slowing as the number of sockets grows. In the standard test the application virtualized on a new Dell server takes about 4 and a half minutes to complete the process, and exactly the same time using SAS HDs in the SAN, or even local SATA HDs or local SSD HDs. Simply changing to the old servers with a local SATA storage the process takes only 1 minute and 30 seconds.
Any help is welcome. Thanks in advance.
Hello,
I’m looking for some recommendations on how to proceed with the setup of a Hyper-V Server 2012 R2 lab environment. I have two systems that I’d like to setup in a cluster. These two systems have enough drives for two RAID volumes, one for OS and one for the VHDs. My initial investigation results are hazy on if I can use these same systems for the clustered storage, and if possible the limitations I will encounter. I do not have a SAN or NAS to use as storage. Can I use these same systems as both the Hyper-V clustered hosts and as the clustered storage? If so, what is the best setup? Will I experience any limitations versus using a SAN or NAS as storage?
Thank you very much for input.
Hi,
Installed Microsoft Hyper-V server 2012 R2 on a computer and would like to create virtual machines on this server for users who requests for a VM based on their specifications ( like RAM=4GB,HDD=60GB etc)...
Added the server to the domain ,assigned the ip and enabled remote management.
when i am trying to access the hyper-v server from a windows server 2008 r2 sp1 server ,it say "An error occured while attempting to connect to server check that the VM service is running and that you are authorized to connect to the server"
Thanks ..
A few months ago I had the following situation on one of our Hyper-V 2012 servers:
-Accidentally changed security permissions on a root folder containing VMs and their storage
-Despite changing them back, Hyper-V manager couldn't restart, change settings for or delete VMs
I created new VMs and attached the original VHDs and got everything running again. I tried to delete the XMLs for the dead VMs but this didn't remove them from the VM list. I've tried using powershell and looking through the registry to delete the VMs but no luck. I keep getting errors about the VM not being able to do anything in its current state.
Although I don't care much about them hanging around. I'm getting funny issues when using New-VM from a remote client to create VMs in powershell. The command always fails only saying:
New-VM: Not Found
Which I believe to be an error trying to enumerate VMs at the server-end. I can use New-VM to create VMs remotely on all of our other Hyper-V hosts, both 2012 and 2012 R2. I'm struggling a bit to find documentation on how to brute-force remove these stale/orphaned VM entries. I have tried twice to reboot the server to see if that would make a difference.
Any tips would be appreciated, thanks
Hi
I have VM that created with Windows Server2008 R2 SP1. This was up without a problem with the windows 8 hyper-v manager. I have recently upgraded my OS with 8.1. Now I have tried to import this VM but itthrowme following message.
This is a real pain when there is no way of doing this. Any help greatly appreciated.

Radika
how to proceed on this and what are the features which gets disabled when we connect to hyper-v server from a windows 2008 or win 7 machine.
