Re: [Xen-users] UEFI bios

[Mark Pryor <tlviewer@xxxxxxxxx>]

dpkg -L xen-utils-4.6

/usr/lib/xen-4.6/boot/hvmloader

check that path/size. If its more than 1.5 MB it has an embedded OVMF bios.

You can try to specify an alternate ovmf bios:
bios_path_override="PATH"

in xl config. This was supported in xen-4.9 and above.

Phil,

The 16.04 distro has Xen 4.6.5 and qemu-2.5, although xen4.6 released using qemu-2.2.

I don't believe there was support for OVMF bios in qemu-2.2, nor in xen-4.6. You can tell if Xen was built with OVMF bios support when you see hvmloader> 1.5 MB, since it is carrying an embedded 1MB blob.

I know the preferences of many 16.04 Xen users and the majority will not use the distro packages, but prefer a source build like this:

If you navigate up you can find xen-4.8 builds too.

I'm trying to emulate a system with UEFI bios.  I set the bios='ovmf'

there some specific path where it is looking for the file, and maybe not

finding it and not logging any error?  I seem to have

/usr/share/ovmf/OVMF.fd and /usr/share/qemu/OVMF.fd.
