[Xen-devel] RE: [New Update] VMX status report against cset #16366

Hi Keir,

>1) Can not insert module "xen-platform-pci.ko" in the 2.6.18 
We found this case is not the issue of PV drivers. It is a wrong
reporting by case.
But I found it is because another bug. 

In (and before) xen-unstable #16157, 64bit Dom0 can do a chroot into a
32bit root file system. 
But since #16281, when doing chroot from 64 Dom0 to 32bit root file
system, it would report "Segmentation Fault".

I tried with Native 64bit Linux, this operation is okay. So I think it
is a new issue. Could you double check?
The reproduce steps,
1. /dev/sda1 is 64bit Dom0 system; sda2 is a 32bit Linux system.
2. Boot to sda1 Dom0.
3. mount /dev/sda2 /mnt/sda2
4. chroot /mnt/sda2

Best Regards,
Yongkang You
