Pro Audio Linux Not Too Distant?

I checked out windows vista for a bit and absolutely hated it. Being a Linux user for 5 years, then an OS X user for 3 years and having to go back to Microsoft is absolute hell. But it's the only I can afford to maintain. PC's are a lot cheaper than Macs. But Pro Audio on linux isn't very conducive to good workflow on my behalf. So I tried Vista, the 14 gigabyte install size was alone enough to send me running. XT2 is running on linux now, so I thought, I almost only use samples to create music anyway, might as well go for it. So I installed a minimal version of XP, put Traktor on it for when I play live, the only program I REALLY need working at this point in time. And put Ubuntu 6.1.0 on my computer.
Anyway, I'm loving it so far. Home sweet home. This new laptop I got has a AMD Mobile Turion which has support for VT, which I just discovered, also virtualization software to actually run side by side with the OS, and not just on TOP. It's still not going to be fast, yes, but I thought I'd give it a shot.
I got KVM-QEMU and KQemu running, put a 150 meg XP install on a virtual drive. So XP itself is only running at about 50 megs of RAM. Got traktor dj studio 3.2.1 installed on it.
It probably runs at least 3/4 of the speed it does on my native XP install. Pretty amazing. The only problem is the GUI in QEMU seems unresponsive and not set for clocked events. It misses mouse clicks. I'm wondering if I can set some command lines to fix the sluggish mouse input. Funny though that the GUI updates very smoothly.
Here's some screenshots.

Same as above + native XT2
Notice the cpu marker, I had it set to high pvoc pitch preservation. Never hit more than half cpu with two delays and the reverb.
OS's seem to be getting closer and closer tech wise, in a year I wouldn't be suprised if this new VT stuff on linux ran windows at 95% it's native speed with no flaws.

i haven't tried any virtualization or emulation or whatever, because it seems kinda slow or whatever. i just went right to the native apps, personally... i think that's the real charm in linux audio - not its emulation, virtualization, but instead it's native homemade applications like seq24, ardour, and wierd ones like kluppe... i dunno, i think linux audio is fan-tab-ulous. i just started using tapiir which is a really great tape delay program...
it's got a lot to offer anyone who's willing to look. tell me, how is ur ubuntu ? do u use the stock kernel? and what is ur soundcard???

14gb base install? Holy Crap! I guess they have to put all that drm somewhere, but that's a bit excessive in my opinion, even for Microsoft.
Haven't tried QEMU for audio apps, but I've used it in the past and it seems very well put together, so if you've got a machine fast enough to handle the virtualization, why not?
To solve your mouselag problem, you might also give VirtualBox link a try instead of QEMU (though I think it's a fork of QEMU). After doing a little hunting, it appears that the mouse lag isn't so much of a problem for the former. VirtualBox also looks like it has some nice additions that QEMU does not.

Don't get me wrong, I love linux audio applications, especially now that EnergyXT runs on it. I really need Traktor running though. I have a windows installation JUST with traktor on it and that's when I'll ALWAYS use it when I play live for stability purposes. But it'd be nice to have it running even if its not 100% functional for when I feel like playing around with it for a little bit.
No customized kernel just Ubuntu 6.1.0
Dell Inspiron 1501
I have a 1.86 ghz AMD Turion 64 MK-56 mobile
1gb ram with 128 video memory shared.
So I don't even have a fast set up. It would work GREAT on a really high-end PC

one of the finest qualities of linux is its ability to utilize hardware. ur system is more than adequate for pro audio with some tuning to the kernel. i understand ur need for traktor, however.

Ubuntu studio will be out in a couple of months, will come with a low latency kernel and all..

That said, I've been performing a lot with the stock ubuntu kernel with no problems at all.
