Re: [Xen-devel] [PATCH] [PV-ON-HVM] Fix evtchn interface

["Liang Yang" <multisyncfe991@xxxxxxxxxxx>]

Hi Kasai,

After applying the patch, the unknown symbol issue is gone. However, I got 
another problem. After I load xen-platform-pci.ko successfully, Xen hangs up 
when I try to load xenbus.ko. Xen died sliently without any prompt when I 
did insmod xenbus.ko. I set up my HVM domain by installing a fresh RHEL 4.4 
from ISO image file which is using 2.6.9-42 kernel by default. Then I 
downloaded a fresh 2.6.16.33 kernel to HVM domain and built that kernel. I 
also built VBD modules on this HVM domain and using the same kernel version 
headers. However, I can still not load Xenbus.ko module. The Xen version I'm 
using is Xen 3.0.4 and the latest Xen_unstable.
Do you know how to solve this problem?

Thanks,

Liang
