Subject RE: Not able to ping to outside network from system VMs
Date Fri, 28 Feb 2014 07:51:12 GMT

Hi Jaypal,
We have configured for a single node setup.

Host/Management Server :  10.44.65.143
IP range :   10.44.64.21 - 10.44.64.30
	      10.44.64.31 - 10.44.64.40
Gateway : 10.44.64.1

During configuration of zone and pod, have taken the Management server IP as DNS and gateway
IP.

We are not able to ping from system VMs to 
a) Gateway
b) Google DNS
c) Corporate DNS
d) Management or Host Server

Following logs are repeating.

Still, we are facing same issue.

Hi,

Change the name server to your internal DNS server in systemvm (/etc/resolve.conf).
I also observed that the google DNS server is pinging but not serving the dns requests.

Thanks,
Jayapal
