How to fix "Failed to allocate resources while connecting to a virtual network. The Ethernet switch may not exist"

Question

Any suggestion how I can fix it without resetting Windows?

I have tried everything basic like switching off and on Hyper-V, deleting and recreating virtual switches, using external and internal ones, resetting network adapters, even windows in-place upgrade and some other tricks I have found on the Internet but nothing helps. I have also tried with clean boot disabling all non-Microsoft services in msconfig. VM starts if no virtual switch is selected.

Just to note, I have another PC with basically the same Windows (cloned by Acronis) and everything is good there!

Hello

Thank you for your question and reaching out. I can understand you are having query\issues related to Hyper-VM can not be started.

1.Note the Virtual Machine ID that is listed in the error 0x80070005 (General access denied error).

2. To give the Virtual Machine ID (SID) access to the .vhd or .avhd file, type the following command, and then press Enter:

icacls <Path of .vhd or .avhd file> /grant "NT VIRTUAL MACHINE\ <Virtual Machine ID from step 1> ":(F)

icacls "E:\VMs\VMName\Disk0.vhd" /grant "NT VIRTUAL MACHINE\5FC5C385-BD98-451F-B3F3-1E50E06EE663":(F)

3. Start the virtual machine.
