RE: [Xen-users] Xen with VCPU from other servers
The closest you can really come to a domU running in two places at once is
state synchronization, where two VMs memory, CPU, and storage states are kept
consistent. Kemari is one option for something like this, and you can see the
kind of performance impact (~30-50% depending on the fabric) that just
-synchronization- entails.
