- 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:-)
