Re: [Openstack] vlan network question

2012-05-16 Thread Vishvananda Ishaya
Yes it is possible to do everything over one interface, but it is probably 
better to separate traffic out over multiple vlans if you can.  You could have 
rabbit and mysql on one vlan (call it the management vlan), and the public 
internet traffic/api on a separate vlan.  Finally you could put all of the vms 
on their own vlan (or if you are using vlan mode as you say, then each project 
will get its own vlan).

 Hi,
 
 I have 2 servers. One is the controller that runs everything except
 nova-compute. Another is a compute node that runs nova-compute only.
 Both of them has only one NIC (eth0) . In VLAN mode, do I need the
 second NIC (eth1) ? If yes in both nodes?
 
 This is what I am tyring to acheive.  Install only one nic in both
 server and via bridge from eth0, route the instances. Is this doable?

 Thanks in Adv!

Thanks for the reply.

Another question :). To have multiple compute nodes (say 5), I can
either use vlan or FlatDHCP mode right?. Also, with FlatDHCP can I
have multiple tenants or I need to stick with VLAN to have multiple
tenants?

Thanks
Paras.
