I'm actually having issues across the board...maybe its because I'm going against the design ideals but I was told that in order to use the local storage on the box and sacrifice VM migration capabilities, all machines had to be in their own datacenter. Pain point number one.

Second pain point is adding additional networks aside from the initial management network doesn't seem to be very intuitive. I'm a network engineer for a living...and I can't figure it out.

Third pain point is ovirt management UI requires a restart semi frequently due to crashing.

I added the network under the networks tab, but I noticed it doesn't ask any interface questions (ok, it could technically attempt arp on all interfaces like a citrix netscaler). I notice theres no ifconfig changes on the host. I also notice that the other interface has a bridge named exactly as the management name in the UI; ovirtmgmt, which is bridged to eth0. OK, so I create a bridge called utility (my network name) and mapped it to a vlan tagged interface I had setup on eth1.21. Everything looks identical to how ovirt setup the initial network. The interface itself works, I can see things on the network etc. Traffic passes.

Trying to run the VM results in errors because its failing network filters, says it doesn't exist etc. All I want to do, is create a VM with some memory, some disk, with a nic on a network, across individual machines. My PXE provisioning will take over from there. Whats the best way to do this? Sorry for all the questions -- your guys' response is great, and I really appreciate the help thus far.

The exact message I get is:

Error while executing action: 
utiltest:


Thanks,
Morgan

Hi,

I think template configuration is definitely not an option for networks with a large amount of segments.

I haven't played with VNIC profiles, but I will tomorrow. I didn't remember seeing any documentation on changing that with a PUT, but I'll look into it. Will report back shortly, thank you!

If I correctly understand what you mean, then that is the current
"intended" behavior - supplying NICs as part of VM creation isn't
supported, and there's this RFE to support it:
https://bugzilla.redhat.com/show_bug.cgi?id=999969

My two original suggestions will apparently have to suffice until this
RFE is realised; either properly configuring the template's NICs before
VM creation or modifying the VMs' NICs following creation.
