That's correct, having a QMP command that lists the values gic-version
can have on the current host would be just great.

If we had that, we could validate the GIC version chosen for a guest,
and expose it in the capabilities XML so that higher-level tools can
provide a list of choices to the user.

Please note that this QMP command would have to work regardless of the
machine type selected on QEMU's command line, because libvirt always
runs a QEMU binary with '-M none' when probing its capabilities.

Cheers.
