Thanks, I needed to confirm before explaining how you might get it to work.

So as this suggests you need to propagate some BIOS tables from the
platform into the guest, I believe the relevant ones are SMBIOS tables.

The xl toolstack doesn't make this as easy as xapi (used by XenServer) and
I'm not 100% sure of the details but I think you need to use the
smbios_firmware string in your guest cfg to a file containing the
extra/override tables which you want added to the guest (the file is in
binary format I believe).

I'm afraid I don't know which specific tables you need (although the
xl.cfg(5) man page lists which ones you can override -- which is probably a
good indication which ones you might need to override), nor how one goes
about "compiling" them, maybe dmidecode can help with some of it? e.g.
"dmidecode --dump-bin smbiosNN.bin --type NN" looks like it should dump
table NN to a binary, then perhaps you can concatenate all the smbiosNN.bin
files you need into the thing you give xl. This is all speculation though,
sorry.

http://lists.xen.org/archives/html/xen-devel/2013-03/msg01850.html might be
of interest, not sure.

If you do manage to figure this out then it would be super awesome if you
could document it for the wiki.

Ian.
