HVM with pv-ops? Seems irrelevant whether the kernel used in a hvm
guest has pv-ops. The point is that HVM live migration appears to work
fine (also according to our internal testing), just pv seems to be broken
(and unfortunately with no consistent crash pattern).

Our normal testing covers local live migration testing for HVM with Pv_ops. These cases can pass in Xen-4.0.0 RCx testing.
And I just now tried HVM live migration between two machines with xen c/s 20964 and Pv_ops, it can work.
