KVM & shared storage

Hi,
Did you have any experience about using KVM with iSCSI or FC as the primary
storage?
It seems it is possible by using cLVM or clustered file systems (GFS2 or
OCFS2).
What is your suggestion?
Is it reliable?
What about the performance?
Thank you.

I would NOT recommend to do this. You will need to set up CLVM with 
things like corosync to get this working.

Then you would only have RAW volumes without thin provisioning nor 
provisioning.

I would suggest to use NFS and then you can use QCOW2 files.
