- host:
  - Intel(R) Core(TM)2 Quad CPU Q6600  @ 2.40GHz
  - Intel S3000AHV
  - 8GB RAM
  - CentOS-5
  - kernel-2.6.18-8.1.14.el5 x86_64 64bit
- guest-1:
  - CentOS-5
  - kernel-2.6.18-8.1.14.el5 i386 32bit
- guest-2:
  - CentOS-5
  - kernel-2.6.18-8.1.14.el5 x86_64 64bit
- guest-3:
  - Mandrake-9
  - kernel-2.4.19.16mdk-1-1mdk 32bit
- guest-4:
  - Windows XP Professional 32bit

start the first guest-1 with 4cpu produce the above hang. (and of course
using kvm-46:-)
