Subject Not able to ping to outside network from system VMs
Date Thu, 27 Feb 2014 07:18:33 GMT
Hi All,

I am setting up a 2-node cloudstack environment.

Management Server :    10.44.189.125
Host Server :      10.44.65.143

I am able to see the system VMs in running state.
But not able ping to outside network from system VMs.

I am not able to ping to corporate DNS or Google DNS from system VMs.
Also not able to ping gateway from system VMs.

Health Check :
root@s-20-VM:/usr/local/cloud/systemvm# ./ssvm-check.sh
