something still ain't right.

ksoftirqd remains pegged near 100%, making the system less than responsive.
a flood of incoming network connections could explain this, or some VM/host
feedback issue, or...?

hmmm, dmesg is full of:
  TCPv6: Possible SYN flooding on port 80. Dropping request

munin's monitoring has been dropping out as well:
  http://webextra.osgeo.osuosl.org/munin/osgeo.org/projects.osgeo.org.html


Some iptables voodoo seems in order.
