Does QEMU work under OpenBSD? But even if it does, it's probably too slow to
use it in production. Also, it might contain bugs and crash, decrease the
security of the host or guest, etc. If I were you and decided on using
virtualization, I'd go with a proven, mature solution. I don't think QEMU is
that mature or that it got enough exposure.

Nothing is impossible (or impossible is nothing). Even operating systems
certified as EAL4+ have been hacked, and some of them have horrible security
tracks, despite being certified. No software is bug-free, so forget about
the concept of "unbreakable" or "unhackable". It does not exist at all.

Being hackable from the Web is just too vague. Your system might have SSH
enabled and a poor password for a particular user, such as that a hacker can
log in and, from there, launch a local attack against the system (local
exploit instead of a remote exploit, like crashing the box), launching a DoS
attack, etc.

As usual, the security of the system depends on the weakest chain. That's
typically the user, or a poor password, or an unpatched system, or a
misconfigured system, or an unqualified administrator, or ... :)

Thanks a lot for your help.
