Choosing a highly-available, networked file system for VM images

Question

What's the consensus here on highly-available, networked file systems for VM disk images?
HA-NFS seems difficult and overly-complicated.
GlusterFS doesn't seem to be well-suited for this task.
Ceph/RADOS seems popular but there isn't much information available.
OCFS2 seem to be suitable but there also isn't much information available.

Actually, I still would suggest taking a closer look at what I had mentioned in your other thread:
[Use OCFS2 to Share Local Storage (DAS) Across OVM Compute Nodes|https://forums.oracle.com/forums/thread.jspa?threadID=2438632&tstart=0]
I still think that this would also solve thus thread. In the end, there is no how-to on how to build that up and you probably will need some help from some experts. I for myself, also didnÄt configure all of that on my own - i left ASM/Cluster part for some contractor to setup and focused on the iscsi-target/initiator setup along with the multipath setup on m VM servers.
Maybe I will do a little write-up, once we get it all sorted out, since we do experience some strage behaviour of our storages boxes, while ASM hammers ob them quite hardly, but I suspect the raid controllers to blame and not the concept… ;)
