Hyper-V is a native hypervisor; it can create virtual machines on x86-64 systems and supersedes Windows Virtual PC as the hardware virtualization component of the client editions of Windows NT. A server computer running Hyper-V can be configured to expose individual virtual machines to one or more networks. Hyper-V Server supports remote access via Remote Desktop Connection. Administration and configuration of the host OS and the guest virtual machines is generally done over the network.

following is my Hyper-v Host configuration.

Hyper-V host running on SSD M.2 and all my VM  VHDX files sitting on local drives (4 x 600 GB Hard Drive - SAS 15K - 3.5" Drives in Riad 5).
I have Two Guest VM's (DC & file server).
I have configured a separate hard disk VHDX (1TB DYnamic) for DATA and attached to my file server.
Then I started transferring my old file server files to new File server DATA Disk.
While transferring data I couldn't access the new file server. The server was in the hung state. But i cold access my other VM which is DC without any issue.

Did the following tuning on Hyper-v setting

Disable VMQ/Enable Jumbo Frame/Disable IPV6

Applying updates to 2 Hyper V VMs (Server 2016) & have been staring at a screen saying 'Getting windows ready, don't turn off your computer' for about 20 minutes now.
Should I start to be concerned or remain patient?
Was burned too many time with updates on 2008 servers, especially SBS...
I have a single Hyper-v host and running two VM's.All the VM's are sitting in local storage
My local storage specs- (Lenovo 600 GB Hard Drive - SAS (12Gb/s SAS) - 3.5" Drive - Internal 15000rpm - Hot Swappable) drive with Raid 5.
My hosting OS Server 2016 running on 128 GB Lenovo Solid State Drive - SATA (SATA/600) - Internal - M.2.

I tried to create a Fixed 1TB VHDX drive and it took me 9-10 hours.

Just wanted to find out is this normal or something to do with my storage.
Xeon E2136Xeon SilverHi,
 I am looking at two separate servers that come with two different CPUs (please see screenshots for details).
 When I compare Average CPU Mark, E-2136 @ 3.3Ghz with 6 cores has 15,338 compared to Xeon Silver @ 1.80GHz with 8 cores that has 10,883. But the price of E-2136 @3.3Ghz  is cheaper than Silver @1.8Ghz. I am going to set up Hyper-V server with two VMs (one VM is domain controller and the other VM is Terminal Server running Quickbooks with 2 users and MS ACCESS database accessed by about 8 users via Remoet Desktop Connection. Btw, MS ACCESS database will be converted to MS SQL database at some point)
Here are website links for the screenshots:

 When you look at CPUs these days, they have so many varieties and down right confusing.
 Which CPU is better and why?

 I created a VHDX file from Windows 2012 Server running as VM on ESXi Host. Then I copied the VHDX file into the Virtual Hard Disk folder in Hyper-V 2016 Server and created  a VM using existing VHDX file, assigned RAM, CPU  and Virtual Network Adapter. When I start this VM, it only shows a blinking cursor at the beginning and stays that way.
 I have tried Legacy Network Adapter and tried to press [F8] to start in safe mode, but to no avail.
 What else can I try?

Hi All

Hope someone can help me. I have a server running with Hyper-V Server 2012 with a Windows VM running on it.

I need to be able to redirect the physical COM port of the server to my VM.

How does one go about doing that?

I have a Windows 2012 R2 Hyper-V server with 3 VMs.  One of the VMs is setup for Remote Desktop Services and we have about 13 users connect into this server to work.  Most of them connect to it from within the office.  Some of the users connect from outside of the office.  The managers asked me if there's a way that I can restrict remote access for some of the users.  They would be able to work at their computer within the office but if they go home and feel like they want to remote into their session, they would be restricted from logging into their session when they're out of the office.  What's the best and most simple way to accomplish this?  Thanks in advance for your help!
I have a failover cluster- it is a 2-node Hyper-V Windows Server 2012, and one of the nodes had failed. I rebuilt the node, and have had weird issues seemingly related to the CNO ever since. One current problem is that failover doesn't work- I have to slow-migrate between nodes, which defeats most of the purpose of the cluster. The cluster consists of two nodes using a 10TB SAN for CSV. What risks to I run by deleting the cluster object and rebuilding it? I would do this off-hours of course, but I'm just curious what issues are likely to surface- I'll be doing this late at night, so I'd like to make sure I am as poised as possible with solutions in hand.
I need to make backups of my system state on my windows 2016 server hyper-v domain controller. The only way for this to work is thru power shell. I am only able to run this for one time. How do I write this t run every 4 hours in PowerShell?

# Runs  from PS on DC1
Register-ScheduledJob -Name “System State Backup” -Trigger @{Frequency = “Daily”; At = “2:00”} -ScriptBlock {
	# Create new Backup Policy
	$Policy = New-WBPolicy

	# Add System State to the policy
	Add-WBSystemState -Policy $Policy

	# Set Backup Location
	$BackupLocation = New-WBBackupTarget -VolumePath "\\bugsbunny\svrA"

	# Add backup location to policy
	Add-WBBackupTarget -Policy $Policy -Target $BackupLocation

	# Start Backup Using Policy
	Start-WBBackup -Policy $Policy

Hello we've got got a bunch of VM's hosted on two server 2016 servers.  All VM's are managed using Hyper-V.  We've got a requirement to enable Secure boot on all connected devices including VM's,  we've got a single VM which we've been able to enable secure boot on.  I've followed the suggestions in the following article, the problem is not all VM's have the Firmware Section & Under Security No Secure Boot just "Encrypt State and virtual machine migration traffic"
Replication ErrorReplication ConfigurationFirewall Inbound RulesHi,
 I have two Hyper-V servers - W2012 (running Windows Server 2012, & W2016 (running Windows Server 2016, on the same network.  When I select the VM on W2012 and go thru replication, I get an error.
(1) I can ping W2016 from W2012 and ping W2012 from W2016.
(2) Both Hyper-V servers are "Enabled as a Replica server" using "Kerberos port 80" and chose "Allow replication from any authenticated server".
(3) I tried to replicate the VM in W2016 onto W2012, but it failed because I could not replicate 2016 VM to older version of HyperV.
(4) so I tried to replicate the VM in W2012 onto W2016, but I am getting this error. (please see the screenshot).
(5) On both Hyper-V servers, I enabled "Hyper-V Replicate HTTP and HTTPS Listeners" and rebooted the servers.
(6) Both Hyper-V servers have the same administrator password.

What can I do?

I just installed a new Office PC (Win 10 Enterprise). I have an old billing program on my prior Win7 Pro PC that I want to keep using. Created a VM of the Win7 PC using Macrium viBoot, installed the Hyper-V role in Win10 and am able to boot / use the VM without issue. Great!

But what about backup? I have Macrium setup to image my Win10 PC daily. Would restoring my Win7 VM (if needed) be a simple matter of restoring all the files in the Macrium viBoot folder (where all VM files are stored I believe).

I realize (and use) VM backup software (Altaro) at my Server clients. But Altaro, Veeam, etc. programs require the Host to be running Server software. Looked at BackupChain but that would need a Server license as well.

I'm hoping just a simple backup of the VM files will suffice in this scenario.

Anyone have experience with Hyper-V backup on a Win10 host?
We are using Windows 10 in a office environment and will soon go to office 365.  How can I remove the unnecessary software from Windows 10.   Also this will act as a golden image for Hyper-V VDI.

 I am trying to convert Windows 2003 Server running virtual machine "FS1_W2003-recovered"  in VMWare ESXi server into Hyper-v virtual machine using Microsoft Virtual Machine Converter and have some questions:
 (1) In Connection option screen, I am not sure if the message means or applies to my situation?
 (2) In Connection option screen, why I can't select "On" for "Final state of source virtual machine"?
 (3) In Summary Screen, should I be concerned about the warnings (1. OS not supported  2. having one USB device) ?
(4) In Completion screen, I see "Uninstall tools" on the 3rd line. I assume it will uninstall VMWare tools? If so, why does it do that? Will it alter or harm existing VMWare VM in any shape or form?  This is where I CANCELLED the conversion because I was not sure what would happen to source VM.

Windows 2012 R2 Hyper-V Image w/ SQL Server 2017 boots to Repair Startup after updates

Tried running:

dism.exe /image:C:\ /cleanup-image /revertpendingactions

from command prompt and got an error about the scratch disk might not be large enough, but no option to change it and said it succeeded.

Rebooted, same error


bootrec /mbr and bootrec /fixboot

This is a new vm and I forgot to check the backup to add it. It is not being backed up so I cannot restore. I do have a backup of the existing state now, but I would prefer tor ecover it if possible

I have also checked hyper-v processor settings, as some posts I found, seem to suggest that it is due to a cpu settings, but options there seem to be limited
Extra avhdx filesHi,
  I have a HyperV  virtual machine that has two disks (P...K1-0.vhdx & P...K1-1.vhdx) - C drive and E drive. Each drive carries three files (vhdx, vhdx.mrt vhdx.rct).
 But then there are extra files of avhdx (4AD ...avhdx & B59...avhdx) seen on the screenshot and I like to get rid of it.
 Here is how they are created.
 I created new virtual machine using first disk - P...K1-0.vhdx. But when I tried to add 2nd disk (P...K1-1.vhdx), I added it to the wrong existing virtual machine (called TS1).
 When I eventually added 2nd disk (P...K1-1.vhdx) to the right virtual machine and started the VM, it complained about "file being currently used ...".
 So I rebooted the hyper-V server and was able to start my virtual machine with P...K1-0.vhdx & P...K1-1.vhdx. But my TS1 VM would not start saying "file being currently used ..." and it was put in "saved state". I deleted "saved state" from TS1 and now TS1 is working now.
 However during this process, two sets of extra avhdx, MRT and RCT  files were created and I like to delete them because they are not used and not intended.
 But I just wanted to check to make sure that I can delete them without casuing problems. Fyi, I have not created any snapshot for any VMs in Hyper-V server.

 Can I just delete them?
I am running a Hyper V cluster with two hyper v hosts and one of the host says Host not responding. We cannot see the GUI when we connected to a monitor, nor we can do a remote desktop connect to the server it simply hangs at creating session while doing RDP. Issue is there are few critical vm's running under it which we cannot take them down or risk loosing them due to some issue in future. Is there a way to get the host GUI back without disturbing the VM's? so I can safely migrate the vm's to another host and perform maintenance once I get access to GUI. As of now I feel its too risky to attempt host migration without knowing the root cause.

I have powershell access to that host and I tried restarting terminal services to attempt successful RDP connection however with no luck too.

Looking forward for experts help to get this resolved

Windows Server Backup SummaryRecovery Option ScreenHi,
I am backup Hyper-V server using Windows Server Backup. The size of the backup is about 1,600GB (C drive for OS, E drive for VMs files) and external USB hard drive  size is 3,725GB.
It ran the backup for three days and it only used up so far 1,594GB.
As I understand it, Windows Server Backup program does not do "incremental" backup on virtual machines; therefore it has to do a full backup each and every time. I noticed that it literally took 9-11 hours to complete the backup in the past 3 days. Very slow considering that the server has USB 3.0 ports and USB hard drive is also 3.0.

However if it has to do "complete" backup (because it can't perform incremental backup), then why do I see > 2,100GB space still available on external backup drive after 3 days of backup?
Does it overwrite previous backup? if that is the case, then I can only go back to previous day to restore?
Hello everyone,

I have a scenario in which there are:
3 x Ex2010 Mailbox Server in DAG (on vSphere cluster)
2 x HT and CAS with NLB configured (on Hyper-V cluster)
2 x UM server
and also hybrid configuration.

I am not really an expert in O365 / hybrid configurations.

As per refresh cycle, I have to move VMs from existing Hyper-v and vmware (all above roles) to new vSphere cluster.

For Mailbox I have planned to create new MailboxServer VMs with new name,IP and add them in DAG, add a copy of each databases to new VMs, remove copy from old VMs and uninstall Exchange from old VMs.
Also will be updating the RPCClientaccessserver, move arbitration mailbox

For HT-CAS and UM, I am planning to use vmware converter to move VMs from hyper-V one at a time to vSphere cluster.
I believe I will have to retain the mac address of NICs from hyper-v vms

I am here for some advice, suggestions and caution I must take, specially with hybrid setup.
appreciate your comments.

Thank you.
I have a HyperV Cluster environment.
One of the servers is not listing the virtual machines.
But VMs are up and running.
I can view the VMs of host01, but not of host02.
Also by the Cluster Manager function I can not manage the VMs.

The error below occurs:
The cluster Resource Hosting Subsystem (RHS) process was terminated and will be restarted. This is typically associated with cluster health detection and recovery of a resource. Refer to the System event log to determine which resource and resource DLL is causing the issue.

A component on the server did not respond in a timely fashion. This caused the cluster resource 'Virtual Machine SRVCWBMON01 (2)' (resource type 'Virtual Machine', DLL 'vmclusres.dll') to exceed its time-out threshold. As part of cluster health detection, recovery actions will be taken. The cluster will try to automatically recover by terminating and restarting the Resource Hosting Subsystem (RHS) process that is running this resource. Verify that the underlying infrastructure (such as storage, networking, or services) that are associated with the resource are functioning correctly.
we have an ongoing issue with cloudcare where we cannot log on to our vm servers.
we have 2 vms, 1 our 2016 dc and the other our 2016 exchange server.

once we get into this “lock out” situation we try closing down the servers but they just hang, so the only way we have been able to resolve this is to hard reset the server.

we have just done this again and now both vms are stuck starting up, where the status shows "merge in progress", but the progress is just sat at 26% for our dc and 7% for our exchange server.

we really need these servers back online, so does anyone know how we can tidy this up and get them operational?

any help much appreciated - desperate!!

Hi All,

Hopefully a quick question...

I have a Hyper-V host which does not have a TPM or BitLocker enabled.

There is a Windows 10 Enterprise guest VM.... On this VM can I enable BitLocker on the guest OS boot drive or only secondary data drives?

Most of the information I can find seems out of date, except Microsoft Docs but i couldn't find this info there..

Errors in FixMyNetworkTCPIP setting on SBS2011IPv6 SettingsResult from running FixMyNetworkDNS Forwarder in DNS ManagerHi,
I converted a physical SBS2011 server into a virtual machine in Hyper-V server 2016.
* Problem: SBS2011 VM ( can't surf the internet.

What is working:
- All workstation PCs can access shared folders from the SBS server.
- All workstation PCs can access the internet. I have backup Domain Controller (
- From all workstation PCs, I can ping the router ( or SBS server ( or any other network devices.

* What I attempted:
When I run FIX MY NETWORK TWICE in SBS console, I get IP 6 error. There is no IP 6 addresses given. When I checked two other SBS2011 servers that I manage, they all have IP 6 address assigned. Presumably automatically assigned during the SBS setup because I did not assign them.
(Fyi, I don't use Exchange related services because it has been migrated to online exchange.)
After running FixMyNetwork, it says it fixed IPv6 issue (please see the screenshot), but when I open IPv6 properties, there is no IP address assigned.

Can you help?
