There are vcenter-like interfaces, but I'm not sure how they handle HA, have a look at ganeti and/or openstack this list is rather more concerned about the low level workings of clustered systems, with tools such as cman or pacemaker (depending on your OS version, I think all current RHEL versions use cman) to monitor and manage availability of your services (a VM is a service in this context), and corosync to keep your cluster in a consistent state. if you are looking for a vsphere replacement, you might have better luck with openstack than tinkering with linux clustering directly, in my opinion. > 2. Are there KVM tools that monitor the zones? You would probably use libvirt interface to manipulate with your KVM instances regards, Pavel Herrmann -- Linux-cluster mailing list Linux-cluster@xxxxxxxxxx https://www.redhat.com/mailman/listinfo/linux-cluster
