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?

Hi Jim,
You could create another VM to check if there is connectivity between them.
Then use tcpdump on the host bridge and on your nic while you ping, check
if you see the packets and their correct tag.
I would also check if you have by mistake a duplicate mac address for the
VM (your will need to check your switch for that).
How did you configured the switch this nic is connected to?
You could also share your current setup config for us to see: (from host
and VM)
- ip addr
- ip route
- brctl show (only for host)
Thanks,
Edy.

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.

I did see that the cluster settings has a switch type setting; currently at
the default "LEGACY", it also has "OVS" as an option. 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.

For the successful ping, can you use ping -I (capital i) to choose the

What address are you pinging the internet?
For the successful ping, can you use ping -I (capital i) to choose the
source address you exit the host with?

Very strange, all looks good to me.
I can try to help you debug using tcpdump, just send me the details for
remote connection on private.
It will also help if you join the vdsm or ovir IRC channels.

Actually, I finally was able to identify the issue and fix it...Turns out
(as you probably expected), it wasn't ovirt...
My upstream provider had some wierd security left over, it limited the MAC
addresses permitted to exit the building, and my ovirt host made the list
somehow while my VMs did not.
I now have two VMs on two different nodes that are online!
Thank you for your help!
