I currently only have two IPs assigned to me...I can try and take another, but that may not route out of the rack. I've got the VM on one of the IPs and the host on the other currently. The switch is a "web-managed" basic 8-port switch (thrown in for testing while the "real" switch is in transit). It has the 3 ports the hosts are plugged in configured with vlan 1 untagged, set as PVID, and vlan 2 tagged. Another port on the switch is untagged on vlan 1 connected to the router for the ovirtmgmt network (protected by a VPN, but not "burning" public IPs for mgmt purposes), another couple ports are untagged on vlan 2. One of those ports goes out of the rack, another goes to the router's internet port. Router gets to the internet just fine.

Not sure if that matters or not. I configured another VM on the network, and static'ed an IP, and could ping the other VM as well as the host, but not the internet. The host can still ping the internet. --Jim
