[Xen-users] doubts: hardware access overhead on domUs, desktop environment layout

[Eduardo Costa Lisboa <eduardo.linux@xxxxxxxxx>]

Hi, guys. I am new to Xen but already work (should I say play?) with
it enough to know the basics of it's characteristics.

My questions are the following:

- is there much overhead on accessing hardware via a domU, like a graphics card?

- I am planning to use Xen on my notebook, so I could learn a bit more
and even boot my other distro's without rebooting and stuff; so, would
it be better to have a idle dom0 and a main desktop on a domU or use
the dom0 itself as the graphic desktop environment?

I have heard that if I gave to a domU direct control of a video card,
I wouldn't be able to use it on my dom0. Thus, I should have two video
cards, one for each one of the domains. Is it correct? And, can I even
have 3D acceleration (on X, via NVIDIA's proprietary driver) on a
domU?

Thanks in advance,
