From mboxrd@z Thu Jan 1 00:00:00 1970 From: Olaf Hering Subject: [PATCH 0/6] xenpaging changes for xen-4.1 Date: Sun, 16 Jan 2011 17:32:29 +0100 Message-ID: <20110116163229.044047464@aepfle.de> Return-path: List-Unsubscribe: , List-Post: List-Help: List-Subscribe: , Sender: xen-devel-bounces@lists.xensource.com Errors-To: xen-devel-bounces@lists.xensource.com To: xen-devel@lists.xensource.com List-Id: xen-devel@lists.xenproject.org These changes make xenpaging work for me. The first one is a fix for a bug I introduced shortly before leaving for vacation. Currently the guest will hang because the ring fills up when the balloon driver removes pages. The second one avoids a crash during BIOS startup. The third one is another version of the machine_to_phys_mapping[] handling. The fourth is only required when the balloon driver is used in the guest. The fifth implements a config option to allow an automated start of xenpaging for a given guest. And the last one lists some action items for xenpaging. As of now, xenpaging will either crash the hypervisor or the guest due to page-out of low memory. Perhaps the building of xenpaging could be disabled in the Makefile? Olaf
