Hello. I'm using debian squeeze with libvirt and kvm and I need to load a
newer version of seabios into qemu. I'd like to do it without overwriting
seabios in the debian package because that might be overwritten on the next
update. I hopend that the <loader> directive in the config would work but it
doesn't.
thanks for any ideas.

As far as I know, the BIOS used by QEmu is completely hidden from
libvirt (this can actually be a problem as some corner cases of virtio
boot support are dependant on the seabios version), so unfortunately
there is nothing which can be done at the libvirt level I think,

virtio and seabios are exactly the reason for my question:) I'll just copy
over the new bios, it will work fine.
thanks for help

I believe there is a command line parameter that could let libvirt point
QEMU at a different bios, but it certainly isn't part of libvirt yet,
and I've not tried how it works

You can fudge this by using a shell script as the "emulator", e.g.
<emulator>/path/to/start.sh</emulator>
For my use case I had the following requirements, which are working
successfully in the attached start.sh scirpt:
- supply smbios type 0 and 1 files
- supply an additional ACPI table
- use a customized rebuilt seabios bin file
For the first req. you must not allow the -uuid arg to be passed or it
won't allow the smbios to be applied
For the second, you must trim the apci header data from a binary acpi,
because that data is given in the command line option.
For the third, the path cannot be specified, so the file must be
in /usr/share/kvm directory and path must not be given.
Attached is my start.sh, you must correct the details as required for
your use case.

That's actually a great idea. I haven't thought about overloading the emulator
directive.
thanks
