[ovirt-users] Questions about network implementation

Hi List, I am currently in the process of evaluating several KVM management packages in order to replace some old Vsphere. I have been running up test labs with the following: * oVirt * OpenNebula * Cloudstack * Proxmox * Ganeti While I am more than happy to script up a few CLI tools and interact with Libvirt directly, that isn’t going to work for most end users of this infrastructure. I am running in to a bit of a challenge around the networking aspect of what I am trying to create here, since most of these management tools assume you are building an all-in-one box deployment, or you manage your own network infrastructure in your datacenter. We have 6 soon to be 8 boxes in a remote DC, and we don’t have any flexibility around the networking. Each box has one NIC, with a public IP, and we have a couple of /27 address ranges to use. We need to specify which port on the switch that /27 will be going to. So what I would like to do is build a private address network across all 8 boxes, either using something like PeerVPN / Tinc or the new VPN features built in to Vswitch, I would then put that on vmbr1 for example. Vmbr0 would be the public internet port on each box, and on one box I would run up an instance of PFSense or similar in a VM which I would route the /27’s to and then forward them to IPs on the internal IP pool. Does oVirt have the ability to manage a network structure such as this, and if so how might I go about it? I've had a read through the docs but couldn't work out how I'd build this type of structure in oVirt. Thanks for such a great peace of software, and I appreciate any suggestions or advice anyone can offer on this issue.
