Actually, I've been reading about the corosync, iSCSI, drbd, libvirt approach. The only thing I don't like about this approach is that you actually need to access the Guest/Domain in order to provide the HA service. My optimal solution would be one that doesn't need you to touch the Guests/Domains in any way and, at the same time, provides HA for storage and computing resources. While I write this, I can't imagine a good way of sharing the Guest's RAM so it is replicated on other hosts. This seems like cluster-like functionality. Is it feasible to setup a cluster or grid which share RAM so a single kernel manages all hosts or something? _______________________________________________ libvirt-users mailing list libvirt-users@xxxxxxxxxx https://www.redhat.com/mailman/listinfo/libvirt-users
