Re: Why not just use KVM and oVirt?
"I run Debian and OpenBSD"
I left out OpenBSD in my comment since it's not very performant compared to Net and Free, which have had a lot more focus on performance. The size of the system isn't a great indicator of performance - it's down to the specifics of the implementation. For example, the GNU userland has tended to be quite memory hungry compared to the BSD ones simply because the official GNU coding style favoured lots of dynamic memory allocation over fixed sized data structures or buffers.
