Re: [ovirt-users] VM Networking not working

[Ondřej Svoboda]

Chris,

in /var/log/vdsm/vdsm.log on a host, you should find JSON data with (also) the 
host's networking information. Can you please share it?

I would suggest to clone the VM and see if inter-VM communication is possible, 
through the bridge. Also, can you try to reach to external networks directly 
from your host beforehand? Can you verify that the tagged VLAN is routed 
properly even from the host? Or an even more basic test: does the VM network 
work with no VLAN tagging?

Thanks,
Ondra

[ovirt-users] VM Networking not working

[Christopher Lord]

I asked this on the IRC channel but I thought I'd ask here too.


I have set up a 3 node hosted-engine ovirt cluster. On each host I have bonded 
2 10Gb ports that I use for Storage, and 2 10Gb ports that I intend to use for 
VM traffic. However when I created my first VM and added a VLAN tagged network 
to it, the VM can't access any external network.


I can see the bond, and the bridge on the host. If I give the bridge an IP on 
the host it can access the network.


Also none of the network information is populated in the ovirt engine web ui 
for the VM. All the Guest Agent Data is blank.


Am I missing something? Please let me know what logs will be helpful to 
troubleshoot.


Thanks,


Chris
