KVM Multiple Networks (Bridged and Isolated) for home project


Hello all,

I am wondering if someone could help me or point me in the right direction please...

So I have KVM installed on my Ubuntu host PC. This has more than enough ram and hdd space for my needs. This is what I am trying to achieve:

1. Create a CentOS 7 SpaceWalk server on a VM guest. This will have internet connectivity using a bridged network to the host Ubuntu server.

2. Create 2x CentOS 7 standard VM guests. These will be on an isolated network so they can communicate with each other for SSH and all other wonderful things but not have any internet connectivity to the outside world.

The aim is to have the SpaceWalk VM push all updates out to the 2 guests.

I am extremely new to all things KVM and would like some guidance if possible.

Thanks for anything anyone can provide.

One feature of VM's is that you can set networking for only the VM's. After all it has a virtual router as part of the specs. The choice is nat, bridged, local and none for nics.

Now you say this. "These will be on an isolated network", so I assume that the nic's on the VM's won't have access at all to the host.

To get access you'd have to enable some access to the host or vm's that are not on local.
