Hello,

I've recently setup a system to test out the live migration feature. So far
i've been able to launch the instances with the shared nfs folder. However,
when i run the live-migration command i encounter this error in the
destination compute node:

2012-07-05 09:33:48 ERROR nova.manager [-] Error during

Any ideas on how to solve this?
