Can the disk image file be booted directly as a virtual machine in an emergency?

Hi Guys,
Thanks for taking the time to reading this and maybe help me out.
In case of an emergency, can I start the virtual machine directly with the disk mirror file?
My environment is ubu + Btrfs

If the disk file format is VHD, I can boot into a virtual machine. It works well, but if it’s RAW format, I failed several times. I hope you guys can provide some suggestions. Thank you very much.


can you try to restore via the live cd?
