Re: [PLUG] dedicating a sound card to a vm


yeah, :) knew it wasn't a type-1. but it does have its own system user
on the host, doesn't it?

I don't know, but it doesn't matter.  The issue is that the host OS take control upon boot time.  The way Xen gets around this is to bind hardware to a "dummy driver" that Xen controls, and thus can attach/detatch hardware to VMs at will.  VMWare Server doesn't have a "dummy driver" per se, so even though the hardware isn't being actively used by the host OS, its still tied up

Even in cases where you can prevent the host OS from using the hardware (ie, the host OS doesn't have drivers), VMWare Server does not have a mechanism for performing the last leg of the pass-through (presenting the device to the VM).

What you want to do is possbile with Xen, but the Xen might make you cry.  Does anyone know if QUEMU can do hardware pass-through for PCI devices?
