Hi,
Unfortunately, I fear no one will see that warning in practice - instead I fear a problem would appear as an obscure regression.
Hmm, yes, have to agree to that. Took me a while to figure what was going on in this case, and regressions causes by this have a good chance to be equally obscure.
See above. ipxe doesn't need fixing.
In comment #29 and #32 of the above bugzilla, it is mentioned there are other workarounds - do those not work in practice? It sounds like maybe this particular rom should just be blacklisted somehow.
The main advantage of the seabios patch would be that it works without requiring the user to configure something. Also figuring that the optionrom is the problem (and not the seabios bootorder logic) isn't that easy.
Changing the guest configuration allows you to (a) just disable the rom, or (b) use ipxe rom instead.
cheers, Gerd
