One more:

 - expose the new APIs via virsh. Michael originally suggsted pretty much
   following the style of 'xm vcpu-pin' and 'vcpu-list'. Seems like a fairly
   reasonable pattern to follow.
    

See the attached patch which adds these commands. eg:

# ~berrange/usr/bin/virsh vcpuinfo Demo03
VCPU:           0
CPU:            1
State:          blocked
CPU time:       13.4s
CPU Affinity:   y-

VCPU:           1
CPU:            0
State:          blocked
CPU time:       5.0s
CPU Affinity:   -y
I've applied your patch on my system (RHEL-AS4, update 2) with Xen 3.0.2-2. The compilation of virsh is OK but the execution is failed. The virsh vcpuinfo command returns all vcpus of the specified domain (the list is OK) but after the last vcpu of the list, I've the following message:

*** glibc detected *** free(): invalid next size (fast): 0x08051dd8 ***
Aborted

With the domain-0, the virsh vcpuinfo is OK. I haven't investigated with the debugger but perhaps you have an idea of what is the problem ?

Thanks,
Philippe Berthault.
