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

["Ed Smith" <esmith@xxxxxxxxxxxxxxx>]

Thanks for your help.  I tried building 32bit XEN with XEN_TARGET_X86_PAE=y and 
then tried booting RHEL4U2 SMP (pae=1) and see the same hang so I do not think 
this is necessarily the reason I'm failing.  Although I realize if I was able 
to get by the hang I'd likely fail elsewhere trying to boot a PAE kernel on a 
non-PAE hypervisor.

I see the same domU hang after the "Uncompressing Linux... Ok, booting the 
kernel." message on both RHEL4U2 and RHEL3U6 SMP guests on either 32bit XEN, 
32bit PAE XEN or 64bit XEN hypervisors.  The uni-processor guest kernels boot 
fine.  It would seem booting a 32 SMP kernel (HVM) on any hypervisor is not 
quite working yet.

Ed

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
