Hi Daniel,
Thanks for the reply. I realised that I am looking for my problem in the
wrong place. I was making changes to the ACPI tables in seabios and then
when they didn't appear in the guest acpidump I assumed that the default
bios was still being used. I realised by getting an error with an
erroneous bios file path that my patched bios was being loaded, but
recently qemu changes now ignore the seabios acpitables and use ones that
are set up in qemu.
Thanks for your help!
Phil

This one is correct approach - what exactly failed when you tried
this ?

xmlns:qemu='http://libvirt.org/schemas/domain/qemu/1.0

This is wrong '-smbios' is for setting up guest data tables,
not for providing firmware images.
