I tried it and it took me approximately 10 to 12 hours to install=20 Windows 7 twice and I didn't even finish installing the last time. Here's what happened. The first time I installed it, it was a na=C3=AFv= e=20 install. Took all the defaults just set up the ISO and let the install=20 run. Then I installed all the updates. Hours went by and it kind of cam= e=20 up and ran but then I tried to install the virt I/O drivers and the=20 Windows installation lost its mind. Did some reading on how to make=20 performance better and on using the virtio drivers in windows. So I start of the second install, same size disk 25 GB, same amount of=20 RAM, 1 GB and installed the ethernet, disk and balloon drivers at the=20 right time. I also changed the cache to none, I/O something to native=20 and I think that's about it. Anyway, that was not really any=20 improvement. It's still was incredibly slow and this time it was=20 complaining about running out of memory and packages install never=20 finished. Just kept going and going going. iptraf reported network io=20 ranging from 3kbit to 100kbit range when the updates were running. I'm accustomed to lesser performance on virtual machines. That's the=20 hazard of a running on old and slow laptop (dell e6400 (2.2ghz core=20 duo, 8gb ram)[1]) but even virtual box is not this slow. So what am I=20 doing wrong? It would be nice to use a slow machine like this as many=20 handcrips don't have a whole lot of resources for buying newer/faster=20 machines. On the other hand, many of them use desktops and work from on= e=20 place whereas someone like me is all over the map (quite literally). --- eric [1] Part of the reason I don't bother upgrading machines all that often= =20 is because it no matter how fast the CPU runs or how much memory I have= ,=20 Windows always runs about the same speed.
