5 I used to run vbox, but ran into some issues along the way and
6 switched to KVM, with virt-manager as a front-end. It is a bit more
7 complicated to get bridged networking set up, but it doesn't require
8 any 3rd-party kernel modules to run. You might want to look into it.
9 It isn't as user-friendly as VirtualBox, but all the features are FOSS
10 (I forget if all the VirtualBox features are open-source - haven't
11 used it in a while). You can run VMs via the front-end, or as
12 daemons/etc.

14 This wouldn't really fit your needs, but in general I'd advise anybody
15 doing virtualization of linux guests to consider running containers
16 instead. They are fairly mainstream technology now - the isolation
17 isn't as good as virtualization from a security standpoint, and I have
18 no idea if you can use one with a graphical console, but otherwise
19 they give you almost all the benefits of running a linux guest with
20 much better performance and far less overhead (no double-caching,
21 etc). I've been moving to containers for more of my daemons as it
22 generally reduces the hassle of updates (more updates to do, but when
23 you do an update only one service can break at a time). Containers
24 can even get their own network interfaces/IPs/etc - just like a VM.
