Re: question of accelerated graphics (from a separate thread) hardware accelerated graphics != direct hardware access
They are synonymous. Linux DRI exists to enable graphics acceleration (among other related things):

While I can understand there might be some times that direct hardware access is needed for a VM, it seems to me that is opening up a huge potential problem from a security (and reliability of host OS) perspective. Personally,
You're right. That's one of the reasons why Xen does not have full DRI support. On the other hand you don't get GPGPU processing and you can't do anything serious with OpenGL rendering. Lack of DRI makes the former impossible and the latter prohibitively slow. There are some DRI pass through hacks for Xen but they aren't especially reliable.
