Following is the log of linux PVHVM live migration:

The original error will be on the receive side. The sender failed because
the receiver closed down.
Please ignore my last post, it was wrong because of the kernel version problem.
I tested again after updating my test environment. Live migration/ save/ restore works well on pvhvm with Xen3.4. So this should not be problem for any PVonHVM domain, just windows domain with pv drivers has this problem.
