Hi
When virsh attach-disk/attach-interface is executed in < Xen 3.0.4, the OS type of domain is NULL in xenDaemonAttachDevice(). As a result, the command becomes segmentation fault.
This patch fixes it by checking the version of Xen in xenDaemonAttachDevice().

I do not understand the patch. Why is that dependant on domain->id < 0 ? Can you explain the logic there ?
That just ensures that this command fails in a sensible way with inactive guests when run on older XenD without the inactive domain management APIs.
Oh right, a domain->inactive flag or some such would be so much more readable. Applied and commited then !
