When we run more than 1 guest domain on a number of different systems AMD, INTEL P4 Xeon Etc. we have seen the error below. This happens with and without hyper threading and in both single and dual CPUS. There have been a few other posts I have seen on this but there was no resolution. This did not seem to happen on the testing network, however once it was placed on the (very busy) live network it started to show up. We are lucky to get 10 mins of uptime with 6 Guests running. The guests are not doing anything, they are just running. Also we have the same error on FC4 using RPMS, and DEBIAN using the binary tar ball. Here is the output kernel BUG at drivers/xen/netback/netback.c:297 (net_rx_action)!

I''m also a Xen newbie, and have tried Xen3.0.0 and unstable to try and get around this problem on my colocated machine, I also had a look around the bugs section and found bug #432 ( http://bugzilla.xensource.com/bugzilla/show_bug.cgi?id=432 ) which seems to describe the same problem. I''ve posted my own logs, etc. there as well (unstable gives a more complete kernel panic log by the looks of it). My machine is a P4 with HT disabled with 1Gb ram nonSMP kernel (SMP does not help either), I''m down to running only 2 VM''s (the crucial ones at 32mb and 256mb ram) until this is sorted, my uptimes vary between 30mins and 6hours, I''ve just cron''d reboots on dom0 every 2 hours so state can be kept while I do not lose connections while everything boots just to ensure services appear lagged rather than down. I also run Debian Sarge on both dom0 and U''s with Xen from the sources. I see the bug had attention last in Dec 2005, and I feel somewhat better that other people are also experiencing this. Ideas welcome! Regards, Francois _______________________________________________ Xen-users mailing list Xen-users@lists.xensource.com http://lists.xensource.com/xen-users
