I have HP BL460c Gen9 blades with BCM57840 NetXtreme II
10/20-Gigabit Ethernet via a HP Virtual connection. In my ovirt 4.1
environment I have fibre channel working great.
However in the new environment that I want to bring the data domain over
too ultimately, I am having issues with ovirt interfering with the hosts
ability to see the Fiber Channel storage. If i build a clean CentOS 7
installation and get my FCoE module installed and Fiber channel set up
on my appropriate interfaces, it works and sees the fiber channel
interface every time I type fcoeadm -i, I can reboot a million times,
does not go away. However once I turn it into a oVirt 4.2 node and add
it to my environment and reboot the blade it is hit or miss if fcoeadm
-i is going to return interface information.
If I then type "systemctl restart network" my fiber channel comes
online, but I should not need to do this. I can see in my dmesg logs
that the fiber channel is initializing on boot.

[ 39.505971] bnx2fc: bnx2fc: FCoE initialized for eno52.
[ 39.506299] bnx2fc: [06]: FCOE_INIT passed
[ 39.516308] bnx2fc: bnx2fc: FCoE initialized for eno51.
[ 39.516654] bnx2fc: [06]: FCOE_INIT passed
Reminder I have not added a FC storage domain yet, because I need to
turn off and detach the domain from the old 4.1 environment first.
However that should not keep the fiber channel interfaces from coming up...
And I need to know its working before I do that.
Below is what an fcoeadm -i should return when it seems to be working.

However if I reboot the node from the ovirt console and wait a few
minutes after it has rebooted then type fcoeadm -i I get the following.
fcoeadm -i
fcoeadm: No action was taken
Try 'fcoeadm --help' for more information.
it is not until I perform a systemctl restart network, that I get the
correct output from above.
Any help or insight into fiber channel with ovirt 4.2 would be greatly
appreciated.
