Actually THAT is the fundamental problem ;)
The physical server is frankly much more powerful than the two guest
running on it. I have the same applications + public web/email running
on old dual core machines with less memory than the guests.

Nothing that's being done is out of ordinary except something ordinary
coupled with two virtual guest doing it at the same thing on the same
physical disks causes everything to go haywire. But because "it" is
otherwise normal, I haven't figured out a way to pinpoint what is it
after the previous issue was solved.

Just my luck :D

Unfortunately not the case. Most of these are basically applications +
email/web servers for small/medium customers so they are usually
scattered at the client's office or different datacenters.
