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