BSOD after P2V

0
0

Hi,

We have P2V'd a physical 2008 R2 Member Server to 2 .vhd files. These where then added to a new VM on Hyper-V 2012 R2. The VM was started and the Integration Services installed. The Server then ran for about 30 minutes fine, until it suddenly did a BSOD indicating that the issue was Page_Fault_In_Nonpaged_Area.

Any suggestions as to the cause?

Cheers


Hyper-V Server Hardware Recommendation

0
0
Can you recommend server hardware specs for Hyper-V supporting test lab conditions? We expect to use it for replicating network conditions (i.e. a PDC, SQL server, web servers, etc.) and regressions. We're not sure what to pick for a hardware configuration. What would you recommend for memory, storage, number of processors?

Visual Studio Emulators for Android doesn't work on Windows 10

0

Hi,

When I try to start emulator the start task fails, with message like below.

10.08.2015 14:06:01: [Critical] Unable to add user to the Hyper-V Administrators group. Exit code 2220.

I was using it on Windows 8.1 where it worked well on the same PC. This proves that my PC meets all requirements and it is properly configured. After clean install of Windows 10 emulator doesn't work. 

Hyper-V on my PC is running well. I can create and run 32 and 64 bit vm's. There is problem with creating android vm's by vs emulator. There is no group "Hyper-V Administrators" and it can't be created.

Tried these solutions:
http://blogs.msdn.com/b/virtual_pc_guy/archive/2010/09/28/creating-a-hyper-v-administrators-local-group-through-powershell.aspx

http://blogs.msdn.com/b/virtual_pc_guy/archive/2008/01/17/allowing-non-administrators-to-control-hyper-v.aspx

also i tried to recreate InitialStore.xml for Hyper-V with needed group and operations but without success. It seems that hyper-v bundled with windows 10 doesn't require any special group to run, create, manage and remove vm's, switches, etc. Emulator thinks different and it can't assign me to group which does not exists.

Hyper-V VM Generation 2 - How to boot from .ISO

0
0

Hi guys, 

Server OS: Windows Server 2012 R2

I have a VM Gen2 with following settings: 

I can boot fine from the same .iso from a Gen1 VM so the .iso is bootable. 

I know that the Gen2 VM uses SCSI instead of IDE, but I have no clue regarding how to boot from the .iso..

Any ideas?

Thanks in advance!

Best regards,

Windows 10 Build 10240 Managing Hyper-V on 2012 R2 Datacenter Cannot Connect

0
0

So, we have a total of six Hyper-V servers in our environment. All six were installed from the same Server 2012 R2 Datacenter ISO. I have been managing these from my Windows 8.1 machine with no issues. I got ahold of Windows 10 build 10240, and I am running into an issue connecting to the servers now.

The strange thing is that I CAN connect to one of them. I cannot figure out what is different on this one server from the other five. Windows updates maybe? I migrated all the VMs off one of the servers I cannot manage remotely, performed all Windows Updates, and I still cannot connect to it.

I am reading that Windows 10 should be backward-compatible with managing Hyper-V on 2012, but on connection, it appears a WMI namespace is missing that the Windows 10 tools are trying to connect to.

I am not trying to use alternate credentials (I read this will NOT work from 10 to 2012 R2). Any ideas why this is not working? Several Google searches have not told me anything so far. I realize Windows 10 has not officially been released yet, but a few of us are testing the waters for compatibility issues.

I would appreciate any help anybody can offer.

Hyper-V reverse initial replication

0
0

In the following scenario:

I have a master and a replica server

The master fails, i can do a (unplanned) failover on the replica. 

The replica is being used until the master is back up again so we need to initiate reverse replication.

Now comes the part i get lost, when setting this up it requires an initial replication too which i don't understand.

You have all the data already on the master, we only need the delta from the replica to be send back to the master.

In my case the vhdx file is 1.4TB large, i don't want to send the entire thing over again when i only have about 400MB of changes.. When i choose 'use an existing virtual machine as the initial copy' it takes even longer then when i choose 'send data over the network'.. I've seen people saying to use : Do not copy the initial replication option on the Initial Replication page.  : but i don't have this option in my reverse replication setup.. 

Any help would be appreciated.

Programs not compatible with Hyper-V

Hello Group

I'm in the process of moving my Xenserver VM's to Hyper-V...

Are there programs that won't run in Hyper-V?   My client has Quickbooks Enterprise and Adobe products (Illustrator and their CS suite)..  Calling their Tech Support, both QB and Adobe says their products won't support Hyper-V.

What your experiences with programs that don't like Hyper-V

Thanks

hyper-v issue: Mouse pointer invisible in Linux Mint 17 (run in hyper-v of windows 10)

0

Hi everyone:

    my problem is, after I installed the Linux mint 17 in windows 10 hyper-v, the mouse was invisible in the guest OS (Linux Mint 17). While the mouse really works, I can click the buttons in the guest OS, it's just invisible. anyone know what happened? I've tried to download the Hyper-v Linux integration services and tried to install it in Linux Mint and failed to do it. The setting of hyper-v shows that all the "integration services" are offered except the "guest services".

Hyper-V applying snapshot after VM was removed

0

Hi all,

I've found that strange hyper-v host server behavior.

After playing with some guest VM, I've decided to delete it and start with a new one.

I've removed it from Hyper-v management consoler, and tryed to delete vhdx files from its folders, but got an error that those files are in use.

I've checked resmon, and found that System process applying snapshots from deleted VM!

Is that a bug, or that's supposed to be like that?

host VM server is 2012R2, guest VM was also 2012R2.

Hyper-V encountered an error while configuring network

0

Hey guys, a little help here

Hyper-V encountered an error trying to access an object on computer 'localhost' because the object was not found. The object might have been deleted, or you might not have the permission to perform the task. Verify that the Virtual Machine Management service on the computer is running. If the service is running, try to perform the task again by using Run as Administrator.

I checked and Hyper-V, VMMS is already running. Tried using both domain administrator and member server administrator account to create new virtual machine but still get the same error. Any idea what the problem may be?


Enabling VMQ with Brocade 1020 adapter

Hi everyone,

I am in the process of converting two Vmware ESXi servers into a Hyperv cluster. however I have had some issues with enabling VMQ with the Brocade 1020 CNA adapters installed on these servers.

I have noted VMQ is not enabled even after I install the latest driver and firmware. get-netadaptervmq command show their vmq status is false. enable-netadaptervmq on the adapters to no avail either.

Anyone has experience with these adapters would shed some light on this?

Much appreciate your help!

Error when creating VHDX via Hyper-V Manager remotely

0
0

Hey all!

So, I installed Hyper-V 2012 Core on a box, patched it, and then joined it to the domain. If I connect to the server via Hyper-V Manager from either a Windows 8 machine or Server 2012 machine and try to create a VM, it says "There was an unexpected error in configuring the hard disk on [Insert VM Name Here]." I feel like I've tried everything. I can not create the disk manually via the Manager on its own, before or after the VM being created. I can, however, create the disk via PowerShell with out a problem! Via PowerShell, I can create a dynamic VHDX disk every time without an issue.

I was curious if anyone has had this problem and/or knows a solution.

Thanks in advance!

Some VMs on host limited network access

I have some VMs can communicate with host and other VMs on host but not outside of host other than DHCP request which works.  Other VMs work fine and new VMs seem to work fine.  Any suggestions?

I have been making lots of network configuration changes on host while trying to configure converged networking.  But that doesn't make sense to me why some VMs partially fail but others work fine.
