I did an insert into the database to add an "xvm" fence mode. After that I had to first change the mode to ipmilan to get rid of a couple of mandatory fields. The setup also breaks when I try to edit a host. The fence mechanism makes a couple of assumptions that don't work with fence-virtd: - fence-virtd uses a keyfile, no username and password.

- fence-virtd uses port=vmname to identify a VM The gui has mandatory username and password fields and the standard port/sshport field only takes numeric values.

Some of the problems I ran into are probably related to https://bugzilla.redhat.com/show_bug.cgi?id=1020344
