Yow. There have been a number of weird checksum problems identified in the past with Xen's networking; a checkin was just made a day or two ago which cleans up the checksum handling in a way which may well help here. We'll have to see whether an updated dom0/domU kernel improves things much. --Stephen _______________________________________________ Xen-users mailing list Xen-users@xxxxxxxxxxxxxxxxxxx http://lists.xensource.com/xen-users |
