You mean what's the best way to store domU FSes in file-backed VBDs? Best if you don't put File VBDs onto NFS. Both NFS and the loopback block driver use a load of RAM, and they tend to OOM when used together. Also, the performance will probably be bad. SANs are nice ;-) There have been threads on using GFS to store guest disk files recently. Has the advantage of making live-migration easier. Better performing might be to run CLVM on the SAN so that all dom0's can see logical volumes stored there, then use logical volumes directly. Lower overhead than using the filesystem layer. I've not tried this, so it's speculation on my part ;-) Cheers, Mark -- Dave: Just a question. What use is a unicyle with no seat? And no pedals!
