RE: [Xen-devel] Testing status of fully virtualized guests (Intel VT) on 32bit XEN unstable

["Zhao, Yunfeng" <yunfeng.zhao@xxxxxxxxx>]

Hi, Ed Smith

Thank you very much for the testing!!

For ia32 testing you should not enable pae=1 in the config.
Ia32-pae guest should not be able to boot on ia32 hypervisor.
Currently it can only work on ia32e hypervisor.
The smp kernel of RHEL4U2 is pae enabled.
This is the reason why you failed to boot smp ia32 guest.
If you want to boot a smp kernel on ia32 hypervisor, you should make the kernel 
by yourself and disable pae in the kernel config.

Thanks 
Yunfeng
