Hi Michael,
Great - so networking is as it should be - I can see it created this kind of network in the logs.. so that all looks correct.. applied your bug fix and I now have a VM working using vmfex
Look forward to ovirt 3.6.4 for these fixes ☺
Many Thanks
David

Hi David) ,
You are looking on the net-dumpxml and it's ok, this is how it should look like - in my setup i see the same, for example -->
# virsh -r net-list
Name State Autostart Persistent
----------------------------------------------------------
;vdsmdummy; active no no
direct-pool active yes yes
vdsm-ovirtmgmt active yes yes
vdsm-vmfex_net active yes yes
brctl show
bridge name bridge id STP enabled interfaces
;vdsmdummy; 8000.000000000000 no
ovirtmgmt 8000.0025b50a0002 no enp6s0f0
vmfex_net 8000.0025b50b0002 no enp7s0f0
# virsh -r net-dumpxml vdsm-vmfex_net
<network>
<name>vdsm-vmfex_net</name>
<uuid>bbb7615a-4f7b-4497-a899-58b11f25d5ae</uuid>
<forward mode='bridge'/>
<bridge name='vmfex_net'/>
</network>
- What you should be looking for is the dumpxml of the 'DOM'(the VM when it's running on the host) and look for the interface type -->
# virsh -r list
Id Name State
----------------------------------------------------
2 v7 running
# virsh -r dumpxml 2
<interface type='direct'>
<mac address='00:00:00:00:00:29'/>
<source network='direct-pool' dev='enp6s0f1' mode='passthrough'/>
<virtualport type='802.1Qbh'>
<parameters profileid='10GbE-VMFEX-B'/>
</virtualport>
<target dev='macvtap0'/>
<model type='virtio'/>
<link state='up'/>
<boot order='2'/>
<alias name='net0'/>
<address type='pci' domain='0x0000' bus='0x00' slot='0x03' function='0x0'/>
</interface>
- The BZ i reported - https://bugzilla.redhat.com/show_bug.cgi?id=1308839
will be fixed on the next version(not the one you have) and it should prevent you from running the VM with vmfex profile network.
Cheers)

Hi Michael,
Thanks for the additional steps and troubleshooting, things are looking healthier, but the virsh config has not changed. I can see a direct-pool configuration which looks correct.
Did it fail to clean up the vdsm-SRIOV interface & associated bridge? Or should they be present as well? I did a reboot of the host and it looks like it sets them all up.

Found your bug report - is this related as well? As it should be resolved in the version I’m using. https://bugzilla.redhat.com/show_bug.cgi?id=1308839

Ok, lets try few things.
- I see you using the latest vdsm 3.6 version and you have the vdsm-hook-vmfex-dev-4.17.23-1.el7.noarch shipped by default. But i also see that you have the old hook installed - vdsm-hook-vmfex-4.17.23-0.el7.centos.noarch, please remove it from the server and re-install the host in ovirt(maintenance+re-install). To make sure you have no conflicts with the old hook and you are using the new one.
- In the VM interface profile dialog please uncheck the 'passthrough' property(first remove the SRIOV network from the VMs vNIC and add it back after editing the profile). The 'passthrough' property shouldn't be checked when using the vmfex-hook.
- Last thing, but not must, go to 'Networks' main tab and choose your network 'SRIOV', go to 'Clusters' sub tab and press the 'Manage network' button --> uncheck the 'Required' checkboxes
from your cluster(because your network attached to 2 servers in your cluster from 3, it is in down state colored with red)
, once you will uncheck the 'Required' from the cluster it will be shown as UP, colored in green.
I believe now it will work for you, please let me know.
Cheers )

Hi Michael,
I’m going to include some screen shots - as I’ve got it all setup exactly how you mention below.. but the config on the Hypervisor is still bridged config.
All the UCS port profiles are correct as we use this config on standalone KVM/QEMU hosts.
See in-line for pics at the appropriate step .
Cheers

Subject: Re: [ovirt-users] Configuring the SRIOV virsh device
Hi again David)
In order to achieve such xml ^^ (the one you describing) you should first of all prepare a proper 'Port Profile' on your UCS manager side.
- In your/from your example you should have 2 Port Profiles([1], [2]) configured in your cisco side(see - http://www.cisco.com/c/en/us/td/docs/unified_computing/ucs/sw/vm_fex/kvm/gui/config_guide/2-1/b_GUI_KVM_VM-FEX_UCSM_Configuration_Guide_2_1/b_GUI_KVM_VM-FEX_UCSM_Configuration_Guide_2_1_chapter_010.html)
[1] profile-ame1-test1
[2] profile-ame1-prep1
- This port profiles should associate with your service profiles(blades)
- If you have those port profiles on your ucs side and they well configured, then you should follow the steps i suggested in the previous e-mail -->
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}|)$}}" --cver=3.5
- Restart your ovirt-engine service
- with --cver=3.5 you can specify your cluster version level. ^^
- If you don't want that it will overwrite your current attributes, you have to send them all as well(like on my example above). ^^
We are using 3.6.3, with the applied patch from https://gerrit.ovirt.org/#/c/54237
# engine-config -g CustomDeviceProperties
CustomDeviceProperties: version: 3.0
CustomDeviceProperties: version: 3.1
CustomDeviceProperties: version: 3.2
CustomDeviceProperties: version: 3.3
CustomDeviceProperties: {type=interface;prop={SecurityGroups=^(?:(?:[0-9a-fA-F]{8}-(?:[0-9a-fA-F]{4}-){3}[0-9a-fA-F]{12}, *)*[0-9a-fA-F]{8}-(?:[0-9a-fA-F]{4}-){3}[0-9a-fA-F]{12}|)$}} 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}|)$}} version: 3.5
CustomDeviceProperties: {type=interface;prop={ifacemacspoof=^(true|false)$;queues=[1-9][0-9]*;vmfex=^[a-zA-Z0-9_.-]{2,32}$;SecurityGroups=^(?:(?:[0-9a-fA-F]{8}-(?:[0-9a-fA-F]{4}-){3}[0-9a-fA-F]{12}, *)*[0-9a-fA-F]{8}-(?:[0-9a-fA-F]{4}-){3}[0-9a-fA-F]{12}|)$}} version: 3.6
2) Install vdsm-hook-vmfex-dev on your server(if you don't using vdsm version 3.6, the vmfex hook isn't installed by default)
# rpm -qa | grep -i vmfex
vdsm-hook-vmfex-dev-4.17.23-1.el7.noarch
vdsm-hook-vmfex-4.17.23-0.el7.centos.noarch
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
[cid:image002.png at 01D17B74.B5A70620]
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)
[cid:image003.jpg at 01D17B74.B5A70620]
- 'Networks' main tab(create network) >> 'vNIC Profiles' sub tab(edit the profile and add the 'vmfex' key), so it would look like:
vmfex = profile-ame1-test1
and/or
vmfex = profile-ame1-prep1
[cid:image004.png at 01D17B74.B5A70620]
5) Go to 'Setup Networks' sub tab under 'Hosts' main tab --> attach the network with the vmfex profile to NIC on host(drag it), it should be the additional NIC, not the one that the management network attached to.
[cid:image005.png at 01D17B74.B5A70620]
[cid:image006.jpg at 01D17B74.B5A70620]
6) Create VM or use exist one, create/add new vNIC to the VM with the vmfex profile
[cid:image007.jpg at 01D17B74.B5A70620]
7) Run VM
Note - only Test hosts 2 & 3 are currently configured with this network - so I expect Host 1 to fail.
[cid:image008.png at 01D17B74.B5A70620]
If your port profile configured properly you should see the proper xml, like you described above ^^ -->
Good luck and kind regards,
Michael B

Hey All,
Still trying to work through this VMFEX stuff, and I know what I want the file to look like at the end.. but not sure how to achieve it from the doco written here
http://www.ovirt.org/develop/developer-guide/vdsm/hook/vmfex/
and
http://www.ovirt.org/develop/release-management/features/network/ucs-integration/
Currently my device looks like this
# virsh -r net-dumpxml vdsm-SRIOV
<network>
<name>vdsm-SRIOV</name>
<forward mode='bridge'/>
<bridge name='SRIOV'/>
</network>
I want it looking like this, then the networking will be as it should be!
A port group would be a vNIC Profile from the looks of things…
<name>vdsm-SRIOV</name>
<forward dev='enp6s0f1' mode='passthrough'> <-- defined as a passthrough device, not a bridge
<interface dev='enp6s0f1'/>
<interface dev='enp6s0f2'/>
<interface dev='enp6s0f3'/>
<interface dev='enp6s0f4'/>
< .. list of interfaces available to it which would need to be manually inputted as a hook>
</forward>
<portgroup name='ame1-test1'>
<virtualport type='802.1Qbh'>
<parameters profileid='profile-ame1-test1'/>
</virtualport>
</portgroup>
<portgroup name='ame1-prep1'>
<virtualport type='802.1Qbh'>
<parameters profileid='profile-ame1-prep1'/>
</virtualport>
</portgroup>
</network>
