Ovirt VDI Solution network issue
Hello, first time poster looking for help on setting up the network for a VDI deployment. A little background, I have Ovirt engine running on a Vmware virtual machine and have added a physical host to serve up virtual machines running windows 7 to our developers. The host has a static IP address and when I create a virtual machine I can see the default network is attached and up but does not receive an IP address. It does have a MAC so I'm wondering if I need to have our network team assign an IP for that MAC? I will be creating around 20 vm's that would get wiped after use so assigning static ip's might cause issues. Am I missing something or is there a better way to setup the LAN for this host? Thanks for any help!

Welcome to the oVirt community! A little background, I have Ovirt engine running on a Vmware virtual
machine and have added a physical host to serve up virtual machines running windows 7 to our developers.
why not using self hosted engine instead of the VMware VM? The host has a static IP address and when I create a virtual machine I can
see the default network is attached and up but does not receive an IP address. It does have a MAC so I'm wondering if I need to have our network team assign an IP for that MAC?

Should the virtual machines be accessible from outside, e.g. to access remote desktop, or do you want to use the oVirt SPICE console?

Yes, if your network team would assign an IP for that MAC, e.g. for static assignment inside the virtual machine or via DHCP. Please note that oVirt allows you to manage the MAC addresses of the VMs. (With the exception of external networks like OVN or OpenStack Neutron networks) oVirt's VM networking is focused on layer 2, and does not care about layer 3 issues like IP address management and routing.
I will be creating around 20 vm's that would get wiped after use so assigning static ip's might cause issues.
I could image that there are some less straight forward solutions like cloudinit, or a script inside the VM possible, but I would prefer to manage the IP addresses outside the guests, e.g. by a DHCP server.

Straight forward would be the use a DHCP server for IP address management. A simple way would be to use a DHCP server of your host management network. The host management network is represented by the logical network "ovirtmgmt" in oVirt. This DHCP server is probably managed by your network team. A more complex way would be to create a dedicated VLAN on layer 2, represented in oVirt by a new logical network with a VLAN tag. All the VDI VMs could be attached to this new logical network and a dedicated node could provide higher layer services like a DHCP server and IP routing between the new VLAN and the host management network. This node could be a usual physical router, or a oVirt VM, with access to both layer 2 networks. Please note that the already existing routers have to learn about the new network, if the VDI clients cannot added to the new VLAN.
Thanks for any help!

Thanks for the reply. That makes sense with the dhcp server and I think I found why its not getting an ip automatically via dhcp. When I use spice to login to windows 7 and go to device manager it does not have a driver loaded for the nic card. The server is a dl380 G7 running centos 7. I've done vdi on Ovirt in the past and don't remember having to install network drivers for Windows boxes but maybe I missed a step? Would I download the drivers from HP and burn to a cd to get them loaded onto the VDI? I only see server nic drivers from HP but maybe their is a universal one or I could search the manufacturers website? Appreciate the help.
Please ignore my last as I was able to attach the virt-iso and get the drivers loaded on the Windows VM. Now the network says Unidentified network ip 169.x.x.x. So back to asking our network admins to assign a ip based on mac address correct? Thanks!
