[Users] ovirt-node trying to use NFS4

Hi, I'm in the early stages of testing an ovirt install, using the official ovirt engine packages + F16. I configured a storage domain to connect to our gluster storage via NFS (pity we can't use gluster natively yet). On the engine server, I added Nfsvers=3 to /etc/nfsmount.conf as instructed here: http://www.ovirt.org/wiki/Troubleshooting_NFS_Storage_Issues I then installed a host via ovirt-node (2.3.0-1) and successfully added the host, but it refuses to connect to our storage domain because it's attempting to mount via NFS4. When I add Nfsvers=3 to /etc/nfsmount.conf on the host, it comes to life. Of course, that will be reset after a reboot. So what are my options here, other than not use ovirt-node? AFAIK, gluster doesn't export NFS4, let alone have options to disable it. And I don't see any way to add nfs mount options when defining a storage domain... Thanks for any pointers, Ian
