Hello!

Yes the DNS address is shown correctly but it looks rather like a DNS problem not responding from the second subnet rather than OpenStack's problem.

I have replaced the DNS server of my provider with the one of Google's (8.8.8.8) and everything seem to be working...

So I 've contact them and waiting to see why all "nslookup" are getting a "REFUSED" from their server.


Thanks for your time.

Hi,

Do you see dns address in /etc/resolv.conf?

Hi!

I have an OpenStack Ocata installation where I have one "selfservice" network and one "provider" network (with 1 external subnet).

This configuration was set using the default installation guide and is working fine.

Now I 've bought a second external subnet from my provider and I 've added it as a second subnet to the previously "provider" network.

I can spawn VMs without a problem and VMs can get an IP from the secondly (newly) configured subnet without a problem.

I can access the VMs to their IP address and from the VMs I can ping anb ssh to other hosts without a problem.

My problem is that the VM when on the new subnet cannot resolve names. Although it has the correct DNS server (which is the same as the previous one) and can ping the DNS server cannot resolve any name.

Any ideas what might be the problem???

Regards,


G.
