Windows 11 22H2 Breaks virtual switches in Hyper-V
After updating to Windows 11 22H2 all my hyper-v VM’s did not work any more. vm’s where in save state and could not start anymore. There is just an easy fix and don’t panic your vm’s will run as normal with the setting change.
First the integration services need to be upgraded, in my case I had vm’s from server 2012 etc but these needs to be upgraded, so far my test lab.
The error was upgrade the configuration version.
as you can see I have several versions, more about these configuration version can be found here
Upgrading the configuration version can be done in the gui easy if you have just a few vm’s or in powershell per vm or all at once.
First lets see the version in powershell ( must run as administrator)
get-vm wvd-w10 |select version
Update-VMVersion -Name “wvd-w10” -force
get-vm wvd-w10 |select version
Update-VMVersion * -force
With these command I updated all vm’s , all are now version 11.0
With this the VM will start, but there was no network connection so there must be an issue with the hyper-v switch.
I noticed there was a default switch, Not sure if I created this in the past but I could not delete this switch, looking at the extensions of the vswitch all filter settings where tagged and that is also the issue.
UNTAG the Filters and the network connection is there Make sure you stop start the VM!
see here the two filters that are checked un check these two and apply and stop start the vm and it is all back to normal.
Annoying yes, but it is fixable and easy to fix, and I could blame my self for this as an Windows internal MVP, I did test the update but not in this scenario or to late I was a couple of builds behind.
Hope this post will help you fixing this issue quickly
