I have just installed a Hyper-V 2012 R2 server, configured it, added it to my domain, added users to its local administrators Group and added it to my hyper-v manager.
I have nop problems with adding a switch and servers, but I am not able to brows the hyper-v servers filesystem from my computer with Explorer using\\Hyper-vname\c$ Is it a Firewall rule I need to change? If yes Which one?
Hello Guys!
I'm having a huge problem in my Hyper-V 2012 R2 environment. Yesterday, 9 of 40 VMs were shutdown automatically, and so, caused a downtime problem to my customers in the business hours.
I checked in the Event Viewer (Application / System / Microsoft - Windows - Hyper) of the Host and VM but I couldn't locate any log related to this unexpected shutdown.
It occurred twice yesterday, the first in the morning and the second in the afternoon. I'm afraid that this issue can happen again. I've tried to locate some logs to identify this problem, but no luck here.
My question: Is there any other place where it can help me in this troubleshooting to find the root cause?
Obs: All the VMs are licensed / activated.
Obs2: The VMs are Win 2008 R2 Std

Hi Experts,
I tried to convert a dynamic VHD to Fixed size VHD. It is taking very long for Creation/Conversion of VHDs of size 250GB or more.
I tried VhdTool from http://code.msdn.microsoft.com/vhdtool
This tool is creating VHD files very fast.
The above link has been retired now.
Is this tool MS proprietary? Is there any license required for using this Tool?
and can I use this tool in my Hyper-V VM?
Any other tools suggested by Microsoft for Creating/Converting VHDs?
Thanks in advance,
Saleem
I have a hyper v server 2012 R2 that has a mismatch on the network adapter index number between the sconfig console and the actual index number. If i go into the network settings in sconfig i see an index number of 17 for the Hyper-V virtual Ethernet Adapter #2. But if i select that index sconfig crashes out to a command prompt. If i use netsh to query the interface the index number is 18. If i try to use the 18 index number in sconfig then it also crashes out to a command prompt.
I am not sure when this discrepancy occurred. The server has been running for well over a year and no network changes have been made since initial setup. I suspect that it happened during an update.
Is there any way to fix this? would be nice to be able to use sconfig to update static dns servers. doing it via netsh is a pain.
Hi Experts,
I am deploying a Custom Linux VM using template.
I have written a powershell script that will get the template and create a new VM from the template using "New-SCVirtualMachine".
But, the VM is started after deployment. I already have the Linux Integration Services installed in my VM. So, I removed "-StartVM" and added "-SkipInstallVirtualizationGuestServices" to avoid guest services installation.
But it is still started in the "Customize Virtual Machine" Process and Guestagent.iso is added to CD of my VM.
Please help in avoiding the VM to start after deployment.
Thanks in advance,
Saleem
Hi,
How to get information about creation of a virtual machine on a Hyper-v host?
I need: host name, time created, creator user.
I saw in Hyper-V-VMMS but I found info about movements of VM between hosts.
Thank's in advance.

Hi,
It it possible to create a shadow of a single CSV volume and then expose it to copy files from, as you can a physical volume? If so, how does one go about this via the command line?
Also, i have read some pretty scary stuff about CSV backup via VSS in the past, but i seem to understand this now resolved with 2012 R2 - is this the case?
Thanks.
Hello, I have a single Windows 2012 R2 server (Host) that will be running 3 VMs for 15 to 20 users. One VM server will be the main domain controller and the other 2 will be a SQL server and a Remote Desktop server. I have 2 onboard gigabyte adapters and 2 gigabyte adapters on an add-in card, the 4 adapters are the all the same model, just to give you as much info as possible. I’m reading a ton of articles and it’s making my head spin. The host server will be doing nothing but running the virtual machines and not connected to any domain. In these articles they talk about having one NIC for the host to do management and some say that you don’t need to do this and can team all of the adapters and then designate a host adapter. The goal for me is to provide the best configuration for performance and reliability. With the changes to Windows 2012 R2, Hyper-V and NIC teaming I may be getting a little confused in my thought process since I haven’t run through this yet, here is what I’m thinking.
Any help on this would be greatly appreciated before I start loading up the server. Thanks Ryan.
Hi,
Running 2012 R2 Server as my main OS, have OpenSuse 13.1 installed as a Guest and using MobaXTerm to connect. Only successful connecting with SSH, but not with the VNC.
VNC Settings: IP 192.168.0.100, Port 5901. When I try to connect and briefly I see the Suse background and then it closes giving me the message "Connection closed". I can browse the file system using the Windows File Explorer and when I try IE I get this:
I'm assuming this is the same reason why the VNC is closing, but I added MobaXTerm to Windows Firewall for Private and Public access. Not even successful with TightVNC added:
So what do I need to do now to get this to work for VNC? Thanks!...
Code is like a box of chocolates!...
Hi,
Since that I installed Windows 2012 R2 and Hyper-v, I notice that is very slow performing copy operations from the VMs to the physical machine (appears to be lock to 10MB). Firs I though that this issue was only between the VMs and the parent OS, now I realized that when copying between this Hyper-v physical host and another physical host in the same subnet I also get only 10MB of speed.
How do I unlock this 10MB limit??
The switch and all NICs are GIGABIT capable and before using Windows 2012 r2, using the same hardware boxes I was doing 400MB of transfers between physical hosts and VMs??!!
Thank you.
Our SCVMM lost connection last night and we are unable to get it restarted. The other vm's came up fine but this server has a status of "Backing Up". This is 2012r2. The only option available is to "start" the server. When I try this I get the error:
The Application encountered an error while
attempting to change the state of
'ServerName'.
Any ideas on how to solve this?
Hi guys,
I am using a 3-node WS 2012 R2 Hyper-V cluster. For all virtual machines I enabled resource metering. However, on a random basis Measure-VM stops displaying numbers, it just returns blank fields instead of values...resource metering is still enabled on a VM, but all values are empty. This happens to random VMs, while resource metering for all other VMs keeps working properly.
The only workaround is to disable & enable resource metering, however this resets values which is obviously a problem.
Has anyone had this problem?
A couple of weeks ago we had an outage that prevented a replica from sending changes. When the outage was resolved, the guest required a resync. The changes were so large that upon starting the resync the disk filled and resync stopped, and the guest paused. I fixed the disk space issue and started the guest and resync operation. However, the resync never fully completed. Upon review of the eventlogs I found the following events:
Event 33618: Change tracking for VHD'xxxxx.avhdx' of virtual machine 'guest' is in error state: %%3493462049 (0xD03A0021). (Virtual machine ID xxxxxxxxxxx)
Event 29270: Resynchronization failed for VM 'guest'. Resynchronization needs to be started again. If this error occurs repeatedly, you can remove replication for this virtual machine, delete the Replica virtual machine, and enable replication again. (Virtual machine ID xxxxxxxxxxx)
Event 32326: Virtual machine 'guest' requires resynchronization to get back into an operational state. (Virtual machine ID D62FB3F1-BC01-45E2-BF49-xxxxxxxxxxx).
After attempting resync several more times and getting the same result, I removed replication for the guest, and then set it back up. The initial seed using external media import was successful, but the guest now requires resync and it is having the same issue where it never seems to complete and the same 3 events are written to the eventlogs.
Anyone know how I can get this working again?
Thanks in advance for you help!
Hi all,
New to Server 2012 and Hyper-V but trying to catch up quickly. I know that you cannot have the Hyper-V and SOFS roles at the same time but I am having a hard time finding clarification on the exact scope of that statement.
Does this mean that the SOFS instance, or cluster in my case needs to run on its own bare metal hardware, or can I have a 2012 R2 Hyper-V server hosting a 2012 R2 VM running the SOFS instance on the same hardware?
I am looking to deploy a Hyper-V HA cluster along with a SOFS HA cluster using two beefy servers and 2-3 JBOD chassis.
Thanks for the clarification.
Friends:
I am struggling with very slow virtual machines.
I have Windows Server 2012 installed on a Dell T620. It has two Intel Xeon E5-2650 2.00GHz chips (20M Cache, 8.0GT/s QPI, Turbo) and 64 G of 1600 MHz RDIMMS. It is set up with two RAID arrays (RAID 1 for OS with two 300G 10k SAS drives; RAID 5 for server stuff with four 600G 10k SAS drives) running on a PERC H710 Adapter RAID Controller (512MB NV Cache).
There are two virtual servers running on the box. One is the domain controller and the other hosts a SQL-based practice management program. The "physical server" hosts HyperV etc.
There are 5 or 6 virtual workstations, each running Win8.1E with one virtual CPU and dynamic RAM allocations of up to 8192MB.
HyperV has two virtual switches ("RDS Virtual" and "Intel I350 Gigabit Network Connection - Virtual Switch"). (I don't actually know why it is set up that way.)
I wonder whether anyone can help me trouble-shoot my poor performance?
I am getting this error constantly on all of nodes:
Available processor sets of the underlying physical NICs belonging to the LBFO team NIC /DEVICE/{6F58A4CD-BBBB-4E4A-B7A2-122CDC06E7A2} (Friendly Name: Microsoft Network Adapter Multiplexor Driver #2) on switch 597752D5-FF11-4436-83B5-449630DF04E9 (Friendly Name: vSwitch) are not configured correctly. Reason: The processor sets overlap when LBFO is configured with sum-queue mode.
Is this anything serious? Any resolution to it?
