Hi,
i'd like to establish a HA-Cluster with two nodes. My services will run inside vm's, the vm's are stored on a FC SAN, so every host has access to the vm's. But how can i keep the config files >(xml-files under /etc/libvirt/qemu) synchronised ? Is there a possibility to store the config files somewhere else ? E.g. a partitition with ocfs2 on the SAN ? If not, what would you do ? Otherweise i'm thinking of a cron-job who synchronises the file each minute with rsync.

This looks simple enough...
On host 1, virsh dumpxml for every running vm to a shared location On host 2, virsh define for these vm's
Do the same the other way around...
Hi Dominique, i don't see a way to write with dumpxml directly into a file. Or do you mean by redirection ?
