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 ?
