[clug] Green/Energy Efficient Linux Computer

[BAXTER,Adam]

You're more than welcome to test kqemu on my Atom based PC at the next CLUG - just let me know beforehand. It might also be a good demo/talk topic. Have we covered VMs before?

Your two other options:

* double check the speedstep options on the Core 2 CPUs - some of those can step down to much lower speeds and can also be underclocked while still leaving the VT option in tact. 

* use a laptop CPU with VT. I'm not sure how feasible this is but I know it used to be possible (Corrections anyone?)


Remember to use PowerTop when you get it all set up!

Agree with others that you'd really have to provide more info on how
much speed is enough for your VM. If the needs are only modest I'd
also be interested in your reasons for Green/low power?  It is running
from a solar system? Or do you just want to feel warm and squishy?

If you want medium performance I think you'd be hard pressed to pass
up a laptop with a Core 2 Duo or cousin. For one laptops are designed
with power usage fairly high on the list. For example I have a X61
Core 2 Duo Thinkpad and VM's work very well in it. (generally via
VirtualBox). On top of this you get all the other power saving
benefits of laptops such as speed stepping CPU's, PCI buses and video
cards that can power up and down, low noise, low heat, inbuilt
efficient UPS, ability to power from multiple input voltages etc....
