The weekend went horribly. I created a second storage domain in order to move all the virtual machines to a higher performance RAID array (From RAID6 to RAID10). My mistake was trying to move two Windows domain controllers from one storage domain to another. The problem is that when I "live" moved the virtual machine disk between storage domains, my Windows Server 2019 virtual machines worked fine until the next reboot. After a reboot, the machine just won't start and throws an error - Status: 0xc0000428 - The digital signature for this file couldn't be verified. Moving back to the "old" domain doesn't help. None of the procedures with VMs worked (Re-create boot area, turn on kernel flag - bcdedit.exe /set nointegritychecks on). I am ready to help and interested in developing Ovirt. I can also provide more information to developers if needed.
