Thanks for doing this, looks good to me, FWIW.

Is the presence/absence of xen-xl support exposed via virsh anywhere? If
so then I can arrange for my Xen osstest patches for libvirt testing to
use xen-xl when available but still fallback to xen-xm. I've had a look
in "virsh capabilities" and "virsh help domxml-from-native" but not
seeing xen-xm, so assuming xen-xl won't magically appear in any of those
places either.

(TBH, this may become moot since I suspect your patches will be well
established by the time my osstest patches hit osstest...)

Ian.
