To expose the VM to your LAN network use Direct Attachment to en1234 as Network Interface of a VM. The DHCP server (most likely your ISP router) will give it an IP such as 192.168..123 and you can connect to it normally. Bridge mode to en1234 is reserved for directing traffic between the host <=> instance. I've setup a VM on Fedora 17 with KVM and have configured a bridge network for the KVM. Both the host and the VM use manual IP configuration, with the host's IP as 192.168..2, the VM's 192.168..10. From the VM I can connect to the host without any problems, but from the host I can't SSH to the VM,even though I still can ping the KVM from the.
