I have a OpenSuse 10.3 with xen 3.1.0 running and it's been running fine for a few months. This past weekend it suddenly started to act up and after some troubleshooting I can now say that it seems like the guests(domU) loose the outgoing network pipe, from the console I can see that the TX counter is stuck at the same value but it's no errors. It behaves as if whatever I try to connect to isn't there. I can reboot the guest but the problem stays, TX stays at 0 while RX counts up. Rebooting the host(dom0) solves the problem for a few hours (seems to be about 2.5h). I tried to look for what the problem can be but don't know where to look. The closest I got was when I narrowed it down to that it doesn't send any network traffic out from any domU and once it happens the domU mac is no where to be found outside the domU (checked brctl showmacs & on the switch) What bothers me most is that it worked fine up until Sunday. I was even out of town for a few days before so I didn't change anything. Also, why does it work for a while after reboot? My setup is not that strange. I have one domu as firewall and another in two DMZs so I have my own network-bridge script that calls the stock opensuse script for i in $(seq 0 4); do $dir/network-bridge "$@" vifnum=$i netdev=eth$i bridge=xenbr$i /usr/sbin/ethtool -K eth$i tx off done and this gives # brctl show bridge name bridge id STP enabled interfaces xenbr0 8000.fefffffff000 no vif0.0 peth0 vif2.0 vif4.0 xenbr1 8000.fefffffff001 no vif0.1 peth1 vif2.1 vif3.0 xenbr2 8000.fefffffff002 no vif0.2 peth2 vif1.0 vif2.2 xenbr3 8000.fefffffff003 no vif0.3 peth3 vif2.3 xenbr4 8000.00508bcfd44d no eth4 vif2.4 The kernel and xen running is stock opensuse # xm info host : enterprise release : 2.6.22.17-0.1-xen version : #1 SMP 2008/02/10 20:01:04 UTC machine : x86_64 nr_cpus : 2 nr_nodes : 1 sockets_per_node : 1 cores_per_socket : 2 threads_per_core : 1 cpu_mhz : 2611 hw_caps : 178bfbff:ebd3fbff:00000000:00000010:00002001:00000000:0000001f total_memory : 4031 free_memory : 0 max_free_memory : 1106 max_para_memory : 1102 max_hvm_memory : 1091 xen_major : 3 xen_minor : 1 xen_extra : .0_15042-51.3 xen_caps : xen-3.0-x86_64 xen-3.0-x86_32p hvm-3.0-x86_32 hvm-3.0-x86_32p hvm-3.0-x86_64 xen_scheduler : credit xen_pagesize : 4096 platform_params : virt_start=0xffff800000000000 xen_changeset : 15042 cc_compiler : gcc version 4.2.1 (SUSE Linux) cc_compile_by : abuild cc_compile_domain : suse.de cc_compile_date : Thu Dec 20 19:57:34 UTC 2007 xend_config_format : 4 So, where should I look for problems? /ps -- To unsubscribe, e-mail: opensuse+unsubscribe@opensuse.org For additional commands, e-mail: opensuse+help@opensuse.org
