I am using CentOS 5.4 on top of the Xen kernel. I am trying to use XenSocket for dom0-domU communication. However, I am getting the following error when I run the sender test code.

BUG: unable to handle kernel paging request at virtual address d12d0024

This is encountered when the sender is running on domU and the receiver on dom0 and the sender calls the connect() call. However, when sender is on dom0 and receiver is on domu, everything works well. This means that I am not able to map shared memory pages from the dom0 into the domU  but the reverse is working.

I guess this is a general kernel error, which may not be specific to XenSocket.

Can anyone please help me?
