No, and it's somehow painful. If unsupported you will get a specific error code back though, so maybe that can be automated in some ways. There is the manually maintained page for driver support at http://libvirt.org/hvsupport.html but being manual means it's often outdated :-\ Also there is some subtleties, for example on Xen the main driver is actually implemenbted as a set of 3 sub-drivers for hv/xend/xenstore so just checking for NULL values in the driver entry point is not completely sufficient to assert support of a feature.
