[libvirt] [PATCH 0/4] Automatically choose usable GIC version

Currently, if no GIC version has been provided by the user, libvirt will default to GIC v2. This is a problem when trying to create new guests on hardware that only supports GIC v3 guests: QEMU will refuse to start a GIC v2 guest, and guest installation will abort immediately. This series implements a way for libvirt to figure out a suitable GIC version itself, without relying on tools such as virt-install to parse the domain capabilities before attempting installation.
