[Xen-devel] [help]domU linux network breakdown but dumpcore recover
Hi All: xen 3.3 dom0 linux :Novell SLES11 domU linux(SLES 10 SP1)have 2 ethernet card, config as follows; ethernet card A config a small network ip for conmunnication with dom0 , ethernet card B config a big network ip for business software. small network always is fine; but big network in domU can''t send packets ,but can receive. the domU run 167 days normally before above network trouble; iptables on domU had been disabled. I don''t know how to do ; so I prepared to dump domU''s kernel core to analyse the question. after I finished the command:xm dump-core 4 /data/2011-1020-1659-IED_143_170_sles10sp1.4.core ; I found the douU became to be paused. then I executed :xm unpause 4 ; But I found the big network in domU has recovered normally. Is it stranger? the attachement has xen_bugtool info. Thank you very much for your help. _______________________________________________ Xen-devel mailing list Xen-devel@lists.xensource.com http://lists.xensource.com/xen-devel
