I do this once or twice a year after updating my Win 10 VMs to the next
feature release: I prepare a bootable rescue image, and try to test it by
having my VM boot off it.
In F31, I cannot get the VM boot off the USB thumb drive. I add the USB
thumb drive in virt manager. It's now listed in "Boot Options". I enable it,
and set it to to be first in the boot order.
The VM still ends up booting the OS off the virtual hard drive.
The OS itself sees the USB thumb drive without any issues.
If, in libvirt-manager the boot menu option is enabled, the USB thumb drive
does not appear as an option.
I tried another bootable thumb drive that I prepared a year ago. The VM
refuses to boot off it, too.
Is anyone able to add and boot off a USB storage device, in F31's qemu VM?
