first of all fully update your centos (a bit newer kernel), then i use
these packages:
http://www.lfarkas.org/linux/packages/centos/5/x86_64/
use libvirtd and virt-manager too and start the guests from there. and
start them manually paralell (i used to reboot the host when i update
kvm, the start virt-manager and start each guests). anyway may be a
newer processor generate the same result as ours.
or if you can send me any kind of debug kvm version i can run it which
can print any additional debug messages etc...

i can just repeat my setup:
- host:
  - Intel(R) Core(TM)2 Quad CPU Q6600  @ 2.40GHz
  - Intel S3000AHV
  - 8GB RAM
  - CentOS-5
  - kernel-2.6.18-8.1.15.el5 x86_64 64bit
- guest-1:
  - CentOS-5
  - kernel-2.6.18-8.1.15.el5 i386 32bit
- guest-2:
  - CentOS-5
  - kernel-2.6.18-8.1.15.el5 x86_64 64bit

packages on the host:
# rpm -qa|egrep "virt|vnc|kvm"|sort
gtk-vnc-0.2.0-4
gtk-vnc-python-0.2.0-4
kmod-kvm-52-1.2.6.18_8.1.15.el5
kvm-52-1
libvirt-0.3.3-2
libvirt-python-0.3.3-2
python-virtinst-0.300.1-3
virt-manager-0.5.2-2
virt-top-0.3.2.8-1
virt-viewer-0.0.2-2
vnc-4.1.2-9.el5

the two guest config in libvirtd are the following:
