In testing <smbios mode='host'/>, I noticed a couple of problems. First, qemu rejected the command line we gave it (invalid UUID); ifixingthat showed that all other arguments were being given literal "" which then made the guest smbios differ from the host. Second, the qemu option -smbios type=1,family=string wasn't supported, which lead to a spurious difference between host and guest. Meanwhile, qemu has a bug where '-smbios type=1,uuid=uuid' must parse as a valid uuid, but is otherwise ignored. The current qemu.git code base _only_ sets smbios uuid from the '-uuid uuid' argument. I've filed a bug against the qemu folks asking whether this is intended (in which case we have to modify libvirt to change the -uuid argument it outputs when smbios is specified), or an oversight (hopefully the latter, since it's still nice to correlate /var/log/libvirt/qemu/....log with the XML uuid even when that differs from the smbios uuid presented to the guest.)
