Hi, we have Xen 3.4.1 Dom0 Debian 5.0 x64 server - headless. Now we would like to install OpenSUSE 11.2 PV domU. Does anybody has pointers how to do it or even ready domU image?

This is a cherry pick of two patches that add support for guest paged out frames in the XCP 2.6.32 dom0 patch queue. First patch propagates the ENOENT returned by the hypervisor in the case of a paged out page, all the way up the call chain to the MMAPBATCH_V2 ioctl. The ioctl is mainly used to harvest those return values and retry. The second patch adds retry loops to all backend grant

Hello, does anyone knows, if and when pvscsi will be available in the official linux kernel? Kind regards. Christian _______________________________________________ Xen-users mailing list Xen-users@lists.xensource.com http://lists.xensource.com/xen-users

Hi Keir: These two patches remove the need for netloop by performing the copying in netback and only if it is necessary. The rationale is that most packets will be processed without delay allowing them to be freed without copying at all. So instead of copying every packet destined to dom0 we''ll only copy those that linger longer than a specified amount of time (currently 0.5s). As it

I inherited a xen server that is setup to have all the VM images hosted on an iSCSI mounted NAS array. We been experiencing a random (about every 2-3 days) issue where xen would crash all the VMs, leaving nothing but the Domain0 running. What appears to be happening is something causes the iSCI mount to hiccup. Running "vgchange -a y" and restarting all the VMs brings everything up.

Hello, we are using 3.4.3 from Gitco.de on 64bit Centos 5.8 and we have PV guests 64bit. According to described security bug we are in danger. What do you suggest? Wait for gitco update or build xen own with patch? Br Peter
