VirtualBox raw drive using UUID instead of device name

You can use the lsblk command like this:

sudo lsblk /dev/sdaX -no UUID

To get the partition uuid but you can also use the device file system.

ls -l /dev/disk/by-uuid

To confirm which UUID you want to use. That file will refer to which ever /dev/sdX matches the UUID.

Then use that in the xboxmanage command.
