Well, that would be fun.. a user-space app bringing the system
down.. Sounds like Windows.. *grin*
Remember, a virtual machine emulates the hardware, it's not a mather of
pass-through.
OTOH, it would be a very nice feature to be able to use exotic hardware
for which no proper Linux support is available (as for digital cameras or ..
err.. what's not supported nowadays?), but only for hardware totally
unsupported by the native OS (thus no VGA, IDE, PICs, DMA and maybe
no IRQ's). It might also be a feature for developing proper support, as all
IO can be monitored by Plex..
But IMHO, the first thing for Plex to concentrate on, is getting it to work on
a basic level: emulating all common hardware on a reasonable speed.
Features like this should be put on a 'nice to have, but not for now'-list.
