Guest VM on XenServer unable to reach network

We have set up a XenServer, and trying to set-up a CentOS 6 guest VM.

The installation went fine (using RHEL 6 template), but I'm unable to properly configure the network. The guest VM is able to ping the host machine, but unable to ping any outside machines or gateway.

The network settings look just fine - same subnet range and valid IP.

Any idea what else I can check?

Thanks!

Solution 1:

I imagine the most likely culprit is the firewall on the host. This can be confirmed by running

/etc/init.d/iptables stop

Which will stop the firewall. Then try your ping tests. Use

/etc/init.d/iptables start

To bring it back up again once confirmed.
