Hi David, I hope that everything working for you) >From your description it seems like you have only 1 vNIC on your UCS blade and >that it is a problem. You should enable an extra vNIC on your UCS >blade(service profile). I'm not sure i understood what exactly happened on your setup, but i think it is because you have only 1 vNIC and you trying to use it as the management network and the vmfex hook. you should have 1 vNIC for the management network --> eth0=ovirtmgmt and 1 vNIC for the network with a vmfex profile --> eth1='vmfex network'(network with vmfex=PortProfile)
Attaching screenshots as an example of how it should look like.

So I found some additional logs.. and from what I understand it’s trying to
delete the ovirtmgmt network from libvirt setup.. but there’s no network
configs in there..

So.. I manually edited the /etc/sysconfig/network-scripts and setup the device
& bridge as expected.. but vdsm didn’t like it.. it was still trying to delete
the ovirtmgmt device.
What I ended up doing in the end is defining the network in virsh (creating
myself an account via saslpasswd2 -a libvirt USERNAME) then creating the
ovirtmgmt bridge
# cat vdsm-ovirtmgmt.xml
<network>
<name>vdsm-ovirtmgmt</name>
<forward mode='bridge'/>
<bridge name='ovirtmgmt'/>
</network>
#virsh net-define vdsm-ovirtmgmt.xml
#virsh net-start vdsm-ovirtmgmt
Something still wasn’t right here.. so I ended up rebooting the host… and then
it was working.. I’m still not entirely sure what I did to fix it.. but it’s
working now…
I’ll continue on the journey and keep this thread updated incase anyone else
runs into the same issues!
Cheers

Hi Michael,
Thanks for this information - it's great, the guide should be updated on the
ovirt webpage to reflect the information you've provided below.
Just to hopefully help someone else out in the future - we had only 1 vNIC
defined in the UCS Service Profile, this caused problems when we enabled
dynamic vnic's on that host.
The resolution was leave the initial interface as it is.. and as a management
interface and setup another interface for the dynamic vnics. Ensure that your
"vNIC/vHBA Placement" doesn't change either!
[cid:image001.png@01D16A64.FCDB9D60]
So in this case eth0 = ovirtmgmt bridge, and ovirt device is the vNICs.
When the system reboots after this change I’ve lost my bridge and vdsmd failed
to start.
I manually setup the first interface again so I can talk to it again and I’ve
even setup the bridge.... but I can’t get it working again? Below is what I see
in the logs. I’ve even tried a re-installation(ovirt maint/reinstall) but no
joy..
I’ve managed to get this working on 1 host.. but no idea what I did that was
different!?.. If I remove the vNIC ovirt it starts working as expected - where
can I find out some more information on what vdsm is doing?

HI David)
If everything configured properly on your UCS side and you have a working Port
Profile id/name your next steps should be:
1) Run for example:
engine-config -s
CustomDeviceProperties="{type=interface;prop={ifacemacspoof=^(true|false)$;queues=[1-9][0-9]*;vmfex=^[a-zA-Z0-9_.-]{2,32}$;SecurityGroups=^(?:(?:[0-9a-fA-F]{8}-(?:[0-9a-fA-F]{4}-){3}[0-9a-fA-F]{12},
*)*[0-9a-fA-F]{8}-(?:[0-9a-fA-F]{4}-){3}[0-9a-fA-F]{12}|)$}}" --cver=3.5
- Restart your ovirt-engine service
- with --cver=3.5 you can specify your cluster version level. ^^
- If you don't want that it will overwrite your current attributes, you have to
send them all as well(like on my example above). ^^
2) Install vdsm-hook-vmfex-dev on your nodes
3) In ovirt engine you can verify that host have the hooks installed under
'Hosts' main tab - > 'Host Hooks' sub tab You should see there: a)
before_device_migrate_destination b) before_device_create c) before_nic_hotplug
4) Create new network and edit the vNIC profile. Choose from the
CustomDeviceProperties the 'vmfex' key(like in your example) and in the right
field enter your Port Profile id/name(the one that is configured on your UCS
side)
5) Go to 'Setup Networks' sub tab under 'Hosts' -> attach the network with the
vmfex profile to NIC on host(drag it)
6) Create VM or use exist one, create/add new vNIC to the VM with the vmfex
profile
7) Run VM
Good luck)

Hey All,
I’ve got a test instance and would like to get vmfex working. I’m very new to
ovirt, so some of the basics are still new to me.
I currently have a 3 node setup which are all configured without vmfex, what
I’d like to do is convert the hosts one by one to use vmfex.
>From the UCS side of things it works and I’m presented with the SRIOV devices
>in the host.. but I can’t get the network config in the ovirt admin setup..
I’m following this guide, but not getting very far…
http://www.ovirt.org/Features/UCS_Integration
This step says to do this, which is fine.. but when I do this I overwrite the
current attribute in there.
engine-config -s
CustomDeviceProperties='{type=interface;prop={vmfex=^[a-zA-Z0-9_.-]{2,32}$}}'
which is…
# engine-config -g CustomDeviceProperties
CustomDeviceProperties: version: 3.0
CustomDeviceProperties: version: 3.1
CustomDeviceProperties: version: 3.2
CustomDeviceProperties: version: 3.3
CustomDeviceProperties:
{type=interface;prop={SecurityGroups=^(?:(?:[0-9a-fA-F]{8}-(?:[0-9a-fA-F]{4}-){3}[0-9a-fA-F]{12},
*)*[0-9a-fA-F]{8}-(?:[0-9a-fA-F]{4}-){3}[0-9a-fA-F]{12}|)$}} version: 3.4
CustomDeviceProperties:
{type=interface;prop={SecurityGroups=^(?:(?:[0-9a-fA-F]{8}-(?:[0-9a-fA-F]{4}-){3}[0-9a-fA-F]{12},
*)*[0-9a-fA-F]{8}-(?:[0-9a-fA-F]{4}-){3}[0-9a-fA-F]{12}|)$}} version: 3.5
CustomDeviceProperties:
{type=interface;prop={SecurityGroups=^(?:(?:[0-9a-fA-F]{8}-(?:[0-9a-fA-F]{4}-){3}[0-9a-fA-F]{12},
*)*[0-9a-fA-F]{8}-(?:[0-9a-fA-F]{4}-){3}[0-9a-fA-F]{12}|)$}} version: 3.6
When I update it using the command above, it replaces it…
When I append the 2 together, I get see vmfex & prop in the ovirt-engine
(screen shot) side of things.. so can someone please check my command to ensure
I’m not missing something!
engine-config -s
CustomDeviceProperties='{type=interface;prop={vmfex=^[a-zA-Z0-9_.-]{2,32}$}}{type=interface;prop={SecurityGroups=^(?:(?:[0-9a-fA-F]{8}-(?:[0-9a-fA-F]{4}-){3}[0-9a-fA-F]{12},
*)*[0-9a-fA-F]{8}-(?:[0-9a-fA-F]{4}-){3}[0-9a-fA-F]{12}|)$}}’
# engine-config -g CustomDeviceProperties
CustomDeviceProperties: version: 3.0
CustomDeviceProperties: version: 3.1
CustomDeviceProperties: version: 3.2
CustomDeviceProperties: version: 3.3
CustomDeviceProperties:
{type=interface;prop={SecurityGroups=^(?:(?:[0-9a-fA-F]{8}-(?:[0-9a-fA-F]{4}-){3}[0-9a-fA-F]{12},

CustomDeviceProperties:
{type=interface;prop={vmfex=^[a-zA-Z0-9_.-]{2,32}$}}{type=interface;prop={SecurityGroups=^(?:(?:[0-9a-fA-F]{8}-(?:[0-9a-fA-F]{4}-){3}[0-9a-fA-F]{12},
*)*[0-9a-fA-F]{8}-(?:[0-9a-fA-F]{4}-){3}[0-9a-fA-F]{12}|)$}} version: 3.6
As soon as I enable vmfex on a host that was previously working.. it stops
working and the network no longer works on the host… (this is not using any of
the config above.. just enabled the vmfex in the UCS manager)
What is the “correct” way to bring a Host in ovirt using vmfex?

David
