Hi - Is it possible to save the state of a virtual domain without stopping it? It looks like ''xm save'' stops the VM. When we want to use it to checkpoint the VM, we then have to restart it. Is it a waste of time or is it necessary anyways? Thanks, Xavier _______________________________________________ Xen-users mailing list Xen-users@lists.xensource.com http://lists.xensource.com/xen-users
