Subject: Re: [Users] Vlan interface on top of bonding
Hi,
vlan tagging for ovirtmgmt interface is a bit tricky.
Here's how I do it:
- configure vlan tag on host(s) and switch - imho not necessary to have a
ovirtmgmt bridge available but vlan tagging configured for your ovirtmgmt
network on your ethx or bondx interface
ovirt-engine supports configuration of the ovirtmgmt as a non-vm network,
untagged.
And on top of that nic (bond in this specific case) configure all of the vlans.
The advantage of this setting is not requiring to perform any manual
configuration at all.
The disadvantage is the inability to connect VMs through the ovirtmgmt network,
which
requires configuring at least one VM network on any of the hosts in order to be
able to
configure nics on the VMs.
Thanks a lot. I never tried this before.
As there are repeating questions about networking I'll try to find some
time this week to write a networking documentation (bonding, vlan
tagging, non-vm networks,...) in oVirt wiki this week.
- create a new datacenter (without hosts in it!)
With the fix for https://bugzilla.redhat.com/909820 (merged), any network can
be editing,
in spite of it's configured on hosts. It will result with network being marked
as 'not synced'
on the host.
- edit ovirtmgmt logical network (if it's not possible: delete it and create
new interface ovirtmgmt with vlan tag)
- put host(s) in new datacenter
- configure network from oVirt webadmin gui (maybe you have to uncheck
verify connectivity between engine and hosts)
I can't say for sure if the steps above will work - maybe you have to do more
directly on the host.
Did a few setups with tagged ovirtmgmt interfaces in oVirt and RHEV but newer
wrote down a definitive guide for it :(
Regards,
René

Hi René,
Tanks for your help. I've tried in the direction you pointed and I was
able to share the bond among other tagged networks. One of the problems
would be how to edit ovirtmgmt network now that it's created, I just
can't find in the way to do it by the web. I've tried starting a hole
new datacenter, but it creates the network and disables all changes.
Thus, I can't mark the ovirtmgmt network as tagged and add other tagged
networks to the bond.
I can't tag the management network neither not use it, so I'm kind of
stuck again.

Hi,
first of all welcome to the oVirt project.
Did you configure vlan tagging for your ovirtmgmt network?
If you're using vlan tagging on (bonded) interfaces in oVirt you have to
add a vlan tag to all logical networks - can't mix tagged and untagged
logical networks.
e.g (same for bonds as well):
Name - VLAN- Network Name
eth0 - eth0.10 - ovirtmgmt
eth0.11 - lan1
eth0.12 - lan2
Hope this helps.
