Xen White Paper
Xen also offers a capability for live migration of
a running OS instance (also referred to as Virtual Machine
Migration). This allows a running guest OS to be moved to
a second machine in a very short time. While other products
on the market today claim live migration as a feature, they
typically cause the migrated application to be unresponsive
for tens of seconds while it is moved. Under Xen, with a
feature that enables copy on write for guest OS pages,
the downtime is as low as 30-60ms, orders of magnitude
faster than previously available.
