Hi,

Awhile back, I suggested these simple patches
(http://markmail.org/message/ysnwmqxd2debfjpa) that would allow the xm
save -c to checkpoint utilizing the live migration mechanism,
minimizing the actual downtime as compared to the default method of
suspending the VM and then copying out all the memory state.  Is there
a reason why this hasn't been implemented for actual use?  I'm working
with Oracle VM flavor of Xen and would like to be able to do quick
snapshots.

Thanks,
Mike
