Public bug reported:
for openstack kilo version, when creating a instance, libvirt creates cirrus
video type in template xml file while is not supported for PPC64 little
endian system. I debug the code and finally find mistake in function
_add_video_driver of file nova/virt/libvirt/driver.py
In function, there is a logic that video driver is determinded by guest arch.
If arch is in (PPC, PPC64) then return vga, otherwise video driver is
determined by other options. For PPC64 little endian system, guest arch is
PPC64LE so that video driver is determined by other option (In our environment,
with kvm virt type and spice disabled , video driver is determined by
hw_video_model) which makes video driver is cirrus . Exception happens when
creating vm instance because cirrus video driver is not supported on power
hardware.
I add PPC64LE arch in the guestarch option and it does works. The patch will
be attached.
