These all seem sane. So it's a swap regression, hopefully
2.6.32.something will have a fix.
Sorry to butt in, but heres something I've found odd:

several of these vms are actually assigned less memory than is stated in
-m, since I used the virt-manager interface to shrink memory size. awiki
is set to 256MB, yet is still somehow using over 800MB of virt? one of
the "anon" maps in pmap shows up as nearly 512MB (544788K). The rest of
the vms show oddities like that as well.
host is debian sid with the 2.6.31-2-amd64 kernel, kvm --version reports:
QEMU PC emulator version 0.10.50 (qemu-kvm-devel-88)
and just for kicks:
