Patch series looks fine to me, and we can certainly use this feature.
One question I have about it: Does this apply to all architectures
equally, or will we need to detect it from capabilities? I mean to
say, if this was added to libvirt version X, then I might mandate that
you have to use libvirt >= X and not bother detecting it (as the
feature is so useful). But if it applies only on some architectures
then we'd have to detect it anyway.
Most but not all QEMU architectures. riscv64 is a notable one that
lacks "-cpu max" in QEMU. For that matter, it may well lack
"-cpu host" too from what i see ?
