Most of our users run managed systems.

I consider management software as a user. Today, most management software launches qemu as root. libvirt is just getting around to fixing this although they still are running it as a single user instead of as the user requesting the vm be launched.

The fundamental problem, is that to use qemu as a non-privileged user, you need to go from userA -> root -> userB. For the lazy, it's easiest just to make userA == userB == root. IMHO, the ideal thing is to always be userA.

If we make this easy for management software to do, they're more likely to do the right thing.
