 Hello,

 I got error caused by:

 Could some one confirm that if Quantum network ONLY supports gateway address: 
 x.x.x.1 format?

Hi Yapeng:

That is correct. We explicitly check in 
nova.network.quantum.manager.QuantumManager

if gateway is not None and len(gateway)  0:
 
if gateway.split('.')[3] != '1':
 
raise Exception(_(QuantumManager requires a valid (.1)
 
   gateway address.))  

Cheers,

Dave.

Yes, until we move to handling L3 in Quantum itself (Folsom), the L3
integration in QuantumManager is pretty simple.

Can you just delete that check?  I'm running a Diablo cluster with a /27 where
.129 is the gateway (it's the lowest address in the subnet), which is a
perfectly valid IP address :)

This does sound valid as it's the lowest lsb 1 address in the range.

What is the current check supposed to prevent ?(I gather novice network
users... but it seems the technology itself should prevent that.)

Yeah, I think its fine to delete the check.  Feel free to remove the check
in your environment and reply back if anything else breaks -- I'll also
submit a nova patch for it.

Thanks,
Brad

Re: [Openstack] [Netstack] nova-manage network creation question

2012-03-15 Thread Yapeng Wu 
Hello, 

I removed the check, the nova-manage command runs fine now.

But the gateway address was not pushing to dnsmasq. 

In Nova code, how does the gateway option is pushed to dnsmasq?

Thanks,
Yapeng
