If the elevated iowait from iostat is on the host you might be able to find something hogging you io bandwidth with iotop. Also look for D state procs with ps auxr. Are you on a software raid?
If you are on linux soft raid you might check your disks for errors with smartmontools. Other than that the only thing I can think of is something like a performance regression in the ide/scsi/sata controller (on host or virtual) or mdadm on host. If the host system is bogged before starting vmware instances I would suspect the former (host controller or mdadm). On 3/11/10, Stefan G.
