I'm pretty sure qemu is in ports but I can't for the life of me think why you'd want to run Linux under Haiku. qemu is horribly slow so if you need to run some Linux-only software either run it under native Linux or start porting it to Haiku, if its open source.

Re: Hosting Linux
In which way do you mean "host"? There's several ways to interpret it; do you mean as a virtual machine, on a Web server, or how?
