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?
Cheers,=20

Hi guys,

We re-sized (expanded) a Server 2003 VM a few weeks back and since
then the CPU load seems to be rather excessive. Also in the oVirt GUI
it reports the disk is misaligned, I've done a bit of reading and it
sounds like the only way to correct the alignment again is to
re-install, is this the only option?

Thank you.
