So you have me intrigued by this alignment concept. I hadn't thought about it in this level of detail before.
I found this site: http://www.tcpdump.com/kb/os/windows/disk-alignment/into.html
which had some good explanations and I used their little utility. It came up with some weird results but also said my drives are aligned.
One VM Server came up with this:

None of my VM's came from older VM's, they were all P2V. All of my servers are Win2K3 (not R2) one is a PDC with exchange 2003 sp2 and the other is a BDC and file server. I have shut down all non-essential VM's and verified that my linux servers are not generating the load/lag.
