Hi David,

The exact setup depends on your requirements - number of NICs whether, you have any of the
NICs bonded, if your management interface is on a tagged VLAN, etc. but in essence (ignoring
bonding and management VLAN tagging):

You're going to have your physical interfaces - eth0, eth1, etc - These should be configured
to be 'up' but have no ip address info in them.
These interfaces should be configured either as part of a bridge (strange bridges with only
one interface connected to each). Ie eth0 > cloudbr0 and eth1 > cloudbr1.
Assuming eth0/cloudbr0 carries the management traffic, the management IP address, subnet etc
would be in ifcfg-cloudbr0

Use cloudbr0, cloudbr1 etc as your network labels in CloudStack.

CloudStack will create (say) guest VLAN 505 on cloudbr1 and it will look like cloudbr1.500
on the host.

The names themselves aren't important (you might want to go with cloudbrMgmt and cloudbrGuest)
just make sure the network labels in CloudStack match.


Regards,


Paul Angus

Subject: advanced networking with kvm

how does one actually setup a cloudstack with kvm and advanced networking.
The documentation is not really clear on this.

For example do i need to create my bridges before i try to add the host in cloudstack or do
i let cloudstack create the bridge's.

Also can you choose the name of the kvm traffic freely or do they need to be in the form of
cloudvirbrxxx

is there a short description or tutorial out there for kvm?
