Re: Hmmmm? VirtualBox doesn't like Intel?
Actually yes, the problem is most likely not VBox, nut instead Windows. One of the dirty little secrets MS does not readily release is that there is more than one MS core, an it can only be canged during install. If you installed Windows on that same VM that was dogging, it would very likely run just fine... well as fine as MS Windows is capable of running, lol Kevin On Jul 4, 2010 8:53 AM, "kitepi...@kitepilot.com" wrote: Sometime ago I got to virtualize this bare-metal WinXP laptop under *Ubuntu and I was happy.

ET I would check to see if the Intel CPU supports virtualization extensions (VT-x, EPT). If so, check to be sure they're enabled in the bios. If not, that would be at least part of the difference. -- -Eric 'shubes' --- PLUG-discuss mailing list - PLUG-discuss@lists.plug.phoenix.az.us To subscribe, unsubscribe, or to change your mail settings: http://lists.PLUG.phoenix.az.us/mailman/listinfo/plug-discuss

Re: OT: (or is it?) Interesting take on PKI and security
Yes they do. The difference being that if public keys are going to be forged in the circle of trust system, a whole lot of systems have to be compromised. With PKI, you're putting all your eggs in that one basket. And if you lose control of it. That's it. Game over. You're in trouble. And that's always the issue with centralization of anything.

" The biggest problem with security is that most (nearly 99%) do not understand it, the reasons for it or how to implement and use it. Those few that do can largely be counted as a very small number (less than 1,000) in the entire field and a lot of them spent years leaning how. I personally know enough to know I *really* don't know nearly enough (and perhaps just enough to keep the honest people honest and that's about it). as for the 2 models presented, each has its own Achilles heal. --- PLUG-discuss mailing list - PLUG-discuss@lists.plug.phoenix.az.us To subscribe, unsubscribe, or to change your mail settings: http://lists.PLUG.phoenix.az.us/mailman/listinfo/plug-discuss
