Subject A VPC Problem
Date Fri, 01 Mar 2013 07:43:47 GMT
Hi,

I met a problem with a VPC in CS 4.0. All the VM instances and the virtual router in that
VPC have stopped now. I get the following information in /var/log/cloud/agent/agent.log

2013-03-01 15:05:27,990 WARN  [kvm.resource.LibvirtComputingResource] (agentRequest-Handler-4:null)

when I try to restart the virtual router on UI, I get the following error message: 

Resource [Host:1] is unreachable: Host 1: Unable to start instance  due to Unable to get answer
that is of class com.cloud.agent.api.StartAnswer

How can I solve this problem? Please help me!
