Hi,

I am trying to set up COLO by following this
http://wiki.xenproject.org/wiki/COLO_-_Coarse_Grain_Lock_Stepping

I was able to follow the step up to

$git am ~/ColoPatchForQemu/*.patch

When I try to run the above command, I got the following error:

error: patch failed: include/hw/xen/xen_common.h:186
error: include/hw/xen/xen_common.h: patch does not apply
error: patch failed: xen-hvm.c:85
error: xen-hvm.c: patch does not apply
Patch failed at 0018 Revert "Xen: Use the ioreq-server API when available"
The copy of the patch that failed is found in:
   /root/xen/tools/qemu-xen-dir/.git/rebase-apply/patch

Please let me know how I can solve this patching error. Thank you!

Victor
