This is just a front-end to libvirt and kvm, so you're building
entirely on solid technologies, and anything you set up with the GUI
can be edited or run or otherwise managed from the command line, and
vice-versa.  It ends up resembling something like VirtualBox or the
old VMWare Workstation edition, but it is all FOSS and in-kernel so it
just is more reliable/etc.

That said, I only use VMs situationally and at this point just about
everything I'm doing is in containers if it can be linux-based.  Way
lighter all-around, even if I'm running a full OS in the container.  I
personally prefer to run my containers with nspawn and virtual
ethernet, so each container gets its own IP via DHCP.

Oh, and for kvm if you want to run your guests on your main LAN you'll
probably need to set up a bridge interface.
