We currenty are carrying the attached patch with our Debian based
distribution, which fixes a very similar issue with the PXE-BIOSs, because
Debian provides it's own compilation of etherboot and iPXE.
As each upgrade threatens to break all your previous snapshots, would it help
to include the BIOSs within the saved state instead of letting qemu pickup the
current external file?
Sincerely
Philipp
