Real-time audio in a virtual machine with an Arch Linux guest ?

Hi,

i was trying to make some audio software (JACK, SuperCollider, Pure Data) run in a virtual machine, using
arch linux as a host. I've been trying with QEMU and VirtualBox, the first one on an Arch host, the latter one
both on an Arch host as well as an OSX host.

Long story short, while ordinary, non real-time audio works just fine (playing YT videos in Chromium etc.),
it seems impossible to make programs like JACK, PureData or SuperCollider run. The sound is always
distorted, JACK doesn't even start, and if it starts, it's not possible to create JACK clients etc.

Is there a specific reason that prohibits doing realtime audio computation on a virtual machine ?

Best,
n
