[ovirt-users] Configuring the SRIOV virsh device

[Michael Burman]

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 )
