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. http://www.osrg.net/kemari/download/xen_summit_presentation_final.pdf Best Regards, Nathan Eisenberg _______________________________________________ Xen-users mailing list Xen-users@xxxxxxxxxxxxxxxxxxx http://lists.xensource.com/xen-users |
