You may already have it. In host, test with ifconfig:
In the output on my system, it shows as virbr0 (other connections are omitted here):
Code:
dmn@Sydney:~$ ifconfig

In 17.10 a few days ago, all I had to install was virt-manager (including the dependencies it brought with it) and no other packages to have this.
It's a different story for 17.04 and 16.04. In 17.04, I recall I installed virt-manager and qemu-system. 16.04 needed several additional packages.
I'n not a technical expert on networking, just an ordinary user, but the bridge gives vm its own ip address on your network. That's important.
