libvirt users - Mar 2017 - Re: MIPS emulation broken - No PCI buses available

I am trying to create a QEMU MIPS guest, so that I can test some code
for big-endian safety.

Every attempt to create a MIPS guest is giving me an error:

   Unable to complete install: 'XML error: No PCI buses available'

It seems like this is a known issue.

   https://www.redhat.com/archives/libvir-list/2016-May/msg00197.html

However, I am still getting this on a fully updated Fedora 25 system
with libvirt-2.2.0-2.fc25.x86_64.

You are probably better off using PPC64 which is big-endian and much more
widely tested in libvirt than MIPS, so actually likely to work reliably.

It seems that patch you quote was never applied to libvirt. There was
some debate in the thread that follows and it seems it was never
resolved.

Please do file a bug against libvirt so this doesn't get lost again.

I did try that, but I wasn't able to get past errors about the
machine type not supporting IDE (or something like that).  I finally
just gave up and use qemu-system-ppc directly, along with an older
Debian QCOW image that I found somewhere.
