Hmm, so with Xen we have two backend impls of the Version API, one talking to the hypervisor which only ever returns the first 2 components, and the other talking to XenD which processes all 3. As you say, in practice the extra version from Xen is effectively garbage So while as root I see # virsh version Compiled against library: libvir 0.2.2 Using library: libvir 0.2.2 Using API: Xen 3.0.1 Running hypervisor: Xen 3.1.0 If run as non-root I instead seee $ virsh version Compiled against library: libvir 0.2.2 Using library: libvir 0.2.2 Using API: Xen 3.0.1 Running hypervisor: Xen 3.730.259 I think instead of this patch to change the virsh driver though, we should change teh xend_internal.c file to ignore the extra_version data from XenD as there's no way to meaningfully interpret it as an int.
