I have an Ubuntu Server machine which is acting as a VM host for KVM guests made with vmbuilder. I want to expose the VM's to the network. Currently, the VM guest can get out to the network, and I can get in to the VM from the host, but I can not access the VM from the outside.
On the host, I have set up a bridge br0 which includes the physical interface.
When I fire up the virtualbox VM Centos starts as I would expect, but
when I try to use yum list updates (or any of several other yum
command I've tried) I get a repo error - "
