just got back to this... the method I usee worked well.
I used a 1GB copper port in my mgmt VLAN to set up oVirt with Gluster
Got it all up and running then used 1 x 10 GB port to create my storage network
I think created to logical networks, one tagged with my static VLAN and the other tagged
with my dhcp VLAN, dragged them both onto the second 10Gb port which is connected to cisco
FEX trunk port - worked perfectly and I can deploy to either VLAN now. I guess I will
keep the 1Gb for management... I think I can transfer it to the 10Gb VLANs most likely,
but didn't want to lose my ovirt engine as this setup seems to be working well for me
at least on the network side.
