Situation: The client is running Windows 2016 Hyper-v and moves the VM to different drive. Now, they can’t start the VM.
Troubleshooting: 1. They should not us copy and past to move the VM. They should use export.
2. Hyper-V virtual machine may not start, and you receive a “‘General access denied error’ (0x80070005)” error message Every Hyper-V virtual machines has a unique Virtual Machine ID (SID). If the Virtual Machine SID is missing from the security permissions on the .vhd or .avhd file, the virtual machine does not start, and you receive the “‘General access denied error’ (0x80070005)” error message that is mentioned in the “Symptoms” section.

3. There are two ways to fix the problem. The easy (but completely insecure) fix is to give Everyone full control of the virtual hard disk file. The “correct” fix it to give read and write access to the virtual machine’s SID.
You can find the virtual machine’s SID by using the Get-VM cmdlet in PowerShell. For a VM named New Virtual Machine the command would be:
Get-VM 'New Virtual Machine' | Select-Object VMID
4. Update the Permissions
The solution is to give the SID Full control of the VHD using the command line.
Tip: Rather than type (or mistype) the SID by hand, cut and paste it from the event log message or from the XML file name in the Virtual Machines folder.
The command:
icacls <Path of .vhd file> /grant "NT VIRTUAL MACHINE\<Virtual Machine SID>":F
Note that there is no space before the :F. For example:
icacls "D:\Virtual Machines\VM01\Virtual Hard Disks\DRIVE01.VHD" /grant "NT VIRTUAL MACHINE\6B78D45F5-71DF-4725-B4B2-E651800BE80EF":F
Once that permission has been added, you should be able to start the virtual machine.
