Ubuntu
xen package

Can you run xen on top of a group of machines?

Asked by Robert Simmons

I would like to be able to have a cluster of machines that have xen installed working as a group to serve guest (domU) operating systems.

In the simplest case, I would have box A and box B. Both would be clustered together and have xen installed on the cluster. Then I can start guest X and it would run across A and B. If I start guest Y, it would also run across both of the boxes in the cluster.

Is this possible?

Sorry, but I've read that, and lots of other things, but it does not answer my question. Please read my question and at least say, yes, no, or I don't know.

AFAIK what you describe is not possible.
What is possible is to have 'close to transparent' failover of a VM from machine A to machine B
