Subject VR unable to reach gateway
Date Wed, 24 Aug 2016 14:52:43 GMT
Hi,

I am running ACS 4.8.0. One cluster with two xenserver 6.5 hosts.
One of the VM's network went unreachable so when I checked VR it was unable to reach gateway.
So I tried to restart VR and did cleanup. But issue is still same. When it rebooted VR, I
saw ping command to gateway which ending with this ,

PING 123.23.24.25 (123.23.24.25): 48 data bytes
/etc/init.d/cloud-early-config: line 574:  2009 Terminated              ping -n -c 3 $GW

But then it did give root login prompt on console. But problem is I am unable to login to
VR anymore since cloudstack just shutdown VR vm from xen and I can't even log into VR console
so I can't check more logs.
Cloudstack shut down VR automatically with this mail alert -





Command: com.cloud.agent.api.Command failed while starting virtual router

Details: Timed out in waiting SSH execution result com.cloud.agent.api.Answer

And on cloudstack management logs I get this error,

Network I am trying to get up is production network, so I need it up asap. What could be the
problem here?
I tried to create new VR, and that seems to reach gateway. Its problem with only this VR.
What if I destroy router, from cloudstack panel? Would it recreate VR automatically? Or any
other suggestion on this issue?
