As the fastest measure, turn off atime (if on) while remounting GFS2 and you will immediately notice a zing in performance. 2. Why would one use GFS2 to store VM? In the absence of CLVM not offering LUNs on which VMs are stored. I understand that step 2 may not be feasible if the system is in production (Well, unless you know that lovely qemu-convert command for handlink disk images or something like that and dd incantations which I can't off had remember). But live storage migration is another issue altogether. I haven't had a suitable opportunity to cut my teeth in the RHEV Cloud as yet. So no comments on it from me as yet. Welcome to the Wonderful world of Redhat HA+VM ! (Its not RHEV please. RHEV is another, well, lovely and cuddly, beast altogether) Get the HA right first, then go for virt during rollouts.
