Video card for VM

It is kinda stupid that it does not just use the video card on the HOST
instead of a FAKE 2D card that is worthles for developers like me. so much
for testing my programs. "MUST HAVE 3D capablity."

Actually it's the other way around. The CPU and RAM is virtualized,
the rest is emulated.

Unfortunately the PC architecture doesn't allow 2 systems to share the
video card, and that's just what is happening when you run a virtual
machine. Any 3D support would either have to be software emulated
(read as painful slow), or there would have to be some kind of shunt
driver in the VM to route calls through to the video card. (Which is
not so easy to do and probably hardware specific.)

All hardware inside a virtual machine is virtualised, apart from the CPU and
RAM which are emulated...

All current software virtualisation products do the same...

D'oh! Of course you're right - apologies, group...

That's the whole point of a virtual machine. If it could touch your real
hardware there'd be a mass of issues and complications. Of course, the
virtualisation software COULD emulate a more sophisticated video card, and
that may be something for the future as the CPU power continues to grow...

I have to agree !! I have to use VM just view and edit photographs since
Vista 64 has no RAW image format support. So it was VM to edit and view
images. Then I find out that Vista 64 will not run the ATI Video Recording
software and neither will VM because it does not even see the real video
card. Then to add insult to injury there is no USB support in VM so you
cannot use any device plugged in unless you make it a network device. Vista
64 has been a major disappointment !!! And now I cannot run my business
without going back to my old XP boxes. Some upgrade !!!!

What can MS do about ATI's software? Isn't that ATI's job?
