Thanks for the reply Jaime,

I'll give a try on shared_lvm drivers and will report back.

Just in case, I've been running a production setup where I run VMs on 
top of CLVM (with full live migration)
for about 1 year just by using Redhat's Cluster Tools and libvirt, 
virsh, virt-manager.

Each VM has it's own block devices (LVs on CLVM) backed by 
fibre-channel. No problems so far.

If you'd like me to test something with this setup, I have a couple of 
nodes that I use for testing
and I could try new code on them.

regards,

Giannis
