I guess this solution won't do Mat a lot of good, does it? cheers, B. one management node, a primary storage (local, redundant like drbd master/master are not supported out of the box and need to be "hacked"), one secondary storage (nfs e.g.) and at least one switch capable of dynamic vlan registration (i forget, 802.something). Personally, I love cloudstack, but for the OP's needs, drbd master/master with a stonith (could be done via IPMI / iDRAC) would be a much better solution. For a two node cluster, i think, REMUS and/or Kemari projects are worth a try for failover scenarios. _______________________________________________ Xen-users mailing list Xen-users@xxxxxxxxxxxxx http://lists.xen.org/xen-users
