Thread-topic: [PATCH, RFC, resend] Re: [Xen-devel] granting access to MSI-X table and pending bit array
Sorry for slow response because I met some trouble on environment setup.

This patch works well. Without this patch, the PV DomU can change the vector 
and cause spurios interrupt to xen hypervisor. With this patch, PV DomU can't 
update the vector anymore. 

Ack.

Thanks
