Subject: [help]domU linux network breakdown but dumpcore recover
Date: Wed, 26 Oct 2011 09:31:38 +0000
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.
