[ovirt-users] creating a vlan-tagged network

[Jim Kusznir]

Hi all:

I've got my ovirt cluster up, but am facing an odd situation that I haven't
pinned down.  I've also run into someone on the IRC channel with the same
bug, no solutions as of yet.  Google also hasn't helped.

My goal is this:

1 physical NIC; two networks:
ovirtmgmt (untagged)
Public (vlan 2)

ovirtmgmt works great.  a VM on Public cannot talk to anything off the host.

Steps to set up:

Datacenter -> networks: created network, checked vm network, checked vlan,
put 2 in the tag box.  Set required.  Save.

I only have one cluster (default), and it automatically added it there.  I
went to the hosts in the cluster, and dragged the unassigned Public network
onto the nic (which already has ovirtmgmt on it).  After completing on all
three of my hosts, the network shows online.

Create VM, assign to Public, inside VM assign its IP, and it cannot talk to
the world.

In troubleshooting, I assigned another IP to the host itself (click pencil
in host network settings).  VM can ping host.  SSH into host, host CAN ping
other machines on the net and the router for the net.  VM cannot ping
anything but host (only have one VM on that host currently).  VM is
isolated until I move it to ovirtmgmt network, then it can get off the host
to the world, etc.

I tried disabling iptables just in case, but that had no effect.

How do I troubleshoot this further?
