Wired network only availabe though bridge - R710 KVM server on Ubuntu 18.04

[gunner71]

Full disclosure, I'm fairly new to Linux, so please bear with me.

I've been trying to get a KVM home server set up on my R710 and I'm running into some trouble after experiencing some hardware crashes.

I had KVM set up with the network bridge working, until one day the R710 crashed due to an unrecoverable memory error. Re-seating the ram in the machine seems to have solved that problem, but the machine still would not connect to my home network. After messing with the netplan config I got the machine onto my network, however it seems to only connect through the bridge, and I am unable to start any of the VM's.

I would like to configure the server so that I can SSH into the R710 to manage virtual machines, and for each virtual machine to have an IP on my network.

Thank you in advance, I'm at my wits end here.
