The above might help, but I think the biggest problem may be your VM. You show very low disk I/O numbers, but a pretty significant fraction of the time waiting for I/O. The previously-suggested iostat output may help nail it down more specifically, but basically you seem to have a big problem with bandwidth for storage access. It's pretty disturbing to see lines in vmstat output which show zero disk in or out, but over 10% of CPU time waiting for storage?!?
that would suggest to me a large number of VMs sharing a single SATA drive, or similar.
