gaming on multiple OS of the same machine?
I am new to Xen and I was wondering if the following construction would be
feasible with the current Xen.
I would like to put 2/3/4 new computers in my house, mainly for gaming.
Instead of buying 2/3/4 different computers, I was thinking of building one
computer with a 4/6/8-core CPU, 2/3/4 GPUs, 2/3/4 small SSDs, and attach
2/3/4 monitors to it, 2/3/4 keyboards and 2/3/4 mouses, and run VGA
passthrough. This would save me money on hardware, and it would also save
quite some space on the desk where I wanted to put them.
If this is possible, I have a few additional questions about this:
1) Would the speed on each virtual machine be effectively that of a 2-core
CPU with 1 GPU? What about memory speed/latency?
2) Is it possible to split dual GPUs, e.g. drive 4 OSes with 2x Radeon HD
6990 (=4 GPUs in 2 PCI-e slots)?
3) How should one configure the machine such that each OS receives only the
input from its own keyboard/mouse?
4) Any other problems or concerns that you can think of?
Thanks in advance,
