[ovirt-users] Creating an Isolated/External Network

Hi all, Obligatory I'm not sure if this is the right place to post and obligatory I am very new here. I could really use some help. I'd like to build an isolated/external network so that I can build two VMs that need to interact with each other and each other alone while they are being built. I'd like to protect them from interacting with other VMs I have and I'd like to protect my other VMs from interacting with them. I attempt to create this network by going to Network > Networks > New, and I make sure to click the "create on external provider" checkbox and select "Disabled" under the "Network Port Security" drop-down menu. When I click "ok" I get the error message: "Error while executing this action: User is not authorized to perform this action". This isn't an issue, I just went to the super user and had him try the same thing, and he gets this error message: "Error while executing action AddNetworkOnProvider: Failed to communicate with the external provider, see logs for additional details". The oVirt log wasn't that helpful, as it just told me the time oVirt failed to create the network. Neither my super user nor I can figure out why this is happening. Would greatly appreciate any advice you can give me. Thanks!
