Deanjo wrote:As far as Hyper-V and VT-d goes, I guess my question would be to you would be what types of devices are you planning to work with VT-d. My experience has been that there are very few consumer products that play well with it. So unless you are planning to have isolated NICs or controller cards I don't really see any advantage going the Hyper-V route.

Flying Fox wrote:The 80-90% red kernel overhead suggested that all those VMs that you are running is causing all sorts of context switches either via I/O loads or just the VM processes juggling for CPU attention.

I submit that soon, the idea of virus scanners/checkers will go away (having been defeated) in favor of disposable VMs that replace today's concept of "browse in incognito mode". With sandboxing, it's starting to be this way already, but soon opening a browser, or any other application, will be the same thing as starting up a VM.Kougar wrote:but again I'm doing it just for fun.

Efforts like Qubes-OS (qubes-os.org) have started to dance around this idea, but still don't quite go far enough.

MarkG509 wrote:In a word, "benchies". I think we need a benchmark for benchmarks about how well they reflect and affect real-world performance. E.g., most browser benchmarks focus on things like time to open a web page, but really >90% of the time people see/feel in real life is network latency. Personally, I can "feel" 3ms, "see" 10ms, but don't care much about anything less than 100ms for desktop stuff (and right, I don't game (much).)

MarkG509 wrote:Popping a digression or two off the stack, I think we're circling around a good point, which is what is the right amount of state to virtualize, and what Virtual Machine Managers can do, or try to do, to help with this. When I first create a VM, it really is throw-away. But after a few days, when I've set it up with all my 'stuff' it starts to become as important to me as the physical machines on which it's running. That tells me I'm doing something wrong by virtualizing the whole thing.
