Build minimal install box, add OpenSSH during installation
Watch your disk partitions!
If you need to change storage locations, follow this: https://linuxconfig.org/configure-default-kvm-virtual-storage-on-redhat-linux#h6-1-create-new-virtual-storage-directory
ssh to box:
# I'm bad sudo su - apt update apt upgrade apt install cpu-checker apt install qemu-kvm libvirt-daemon-system libvirt-clients bridge-utils virtinst virt-manager systemctl is-active libvirtd # should output "active" usermod -aG libvirt $USER usermod -aG kvm $USER exit # Do this as your user also sudo usermod -aG libvirt $USER sudo usermod -aG kvm $USER sudo brctl show

This was needed in CentOS 8, not sure about Ubuntu 20.04 yet:
Set up network bridge: Cockpit - Networking - Add Bridge Select your ethernet card (em1) *(ymmv) Name - bridge0 Reboot. Really. This may save some headaches later.
For desktop OS type guests, you should be good to go, for servers you have to use a bridge to get on the right network.
Assuming you added the bridge above (Cockpit – Network – Add Bridge)
Virtual machines – VM – Networking – Interface Type – Bridge to LAN, Source – bridge0, e1000e or virt, whatever.
Restart the VM, it should appear on your network. You may have to reboot the host if this is the first time through!
Beware that firewalld and iptables are all in this mess! You may have to enable ports or disable the firewall on the LAN side to get your server to work.
If you can’t build a new VM or can’t connect, reboot the box at least once before freaking out.
ISO’s to install from
ISOs should live in /var/lib/libvirt/images/ probably want to mount that as a read only nfs mount to your NAS:
Go to cockpit – storage and add the NFS share to that path, stupid easy.
