Hi Neil, To severely impact iops with a single nonaligned VM - image the is rather unusual.
Can you please be more specific: IIRC, to run into the misalignment scenario you need block backed storage for your VM. So FC / Posix / iSCSI but not NFS. - The CPU load of the visualization host or the VM? - Can you confirm (eg. with top) that you have constant a high IO Wait (>20%) there?
