[libvirt] [PATCH v3 0/3] qemu: Deal with panic device on pSeries

[Andrea Bolognani]

Currently, having the <panic> element in a domain XML prevents it from
starting on pSeries. The error message in this case is not very accurate,
and the first commit improves it.

Since the guest firmware provides the same features as the pvpanic
device for pSeries guests, the element should be allowed. The second
commit implements this change.

It being part of the firmware, the <panic> element should actually
always be present in the domain XML: the third commit makes sure
this is the case.

Andrea Bolognani (3):
  qemu: Improve error message for missing QEMU_CAPS_DEVICE_PANIC.
  qemu: Allow panic device for pSeries guests
  qemu: Automatically add <panic> element for pSeries guests.
