Hi all, I had posted about MCA support for Intel64 before. It had only a function to log the MCA error data received from hypervisor. http://lists.xensource.com/archives/html/xen-devel/2008-09/msg00876.html I attach patches that support not only error logging but also Page Offlining function. The page where an MCA occurs will offline and not reuse. A new flag 'PGC_reserved' was added in page count_info to mark the impacted page. I know that it is better to implement the page offlining for general purpose, but I implemented for MCA specialized in this first step. And I also implement the MCA handler of Dom0 which support to shutdown the remote domain where a MCA occurred. If the MCA occurred on a DomU, Dom0 notifies it to the DomU. When the notify is failed, Dom0 calls SCHEDOP_remote_shutdown hypercall.
