Hi,
The patches doesn't apply on master anymore due to new capabilities being
added in mainline, so I've rebased the patches with latest master here in case
someone wants to test them:

Thanks,
Daniel

Hi,
This v2 has changes proposed by Peter and Daniel on the v1
review. Peter's reviewed-by tags were kept when applicable.
The usability change made is that, now, we'll fail to launch powernv
domains that has a pnv-phb* device and it's running a QEMU version
that doesn't support these devices to be user creatable. Trying to
run the 'powernv8-basic' domain with a QEMU 6.2.0 binary will result
in an error:
$ sudo ./run tools/virsh define ../tests/qemuxml2argvdata/powernv8-basic.xml
error: Failed to define domain from ../tests/qemuxml2argvdata/powernv8-basic.xml
error: unsupported configuration: The 'pnv-phb3' device is not supported by this
QEMU binary
Using the current QEMU upstream will allow the domain to be defined and
started.
Changes from v1:
- all tests are now using CAPS_LATEST;
- QEMU_CAPS_DEVICE_PNV_PHB3_ROOT_PORT is no longer being used. Capability
for the pnv-phb3-root-port is infered to exist if the capabilitity for
its PHB (QEMU_CAPS_DEVICE_PNV_PHB3) is present. Same thing for the
case of QEMU_CAPS_DEVICE_PNV_PHB4_ROOT_PORT and QEMU_CAPS_DEVICE_PNV_PHB4;
- QEMU_CAPS_DEVICE_PNV_PHB3 and QEMU_CAPS_DEVICE_PNV_PHB4 are no longer
being probed. They are being set by hand after checking for QEMU
version in virQEMUCapsInitQMPVersionCaps();
- patch 01 (QEMU ppc64 capabilities for qemu 7.0):
* dropped since it's already upstream
- patch 09 (forbid powernv domains migration):
* removed. This will be handled on QEMU side
- patch 14 (new):
* added documentation of the different semantics 'targetIndex' will have
for PowerNV PHBs
- several other minor changes suggested by Peter
