Inspired by Craig & I decided to try my luck on Windows 7 beta on ESX. I was able to get it running but I was not so lucky. I am not sure why the boot up time is pretty long. The installation time also take quite long without much info what is happening backend (Can’t complain much as it is still beta). The good thing is once is fully boot up it runs pretty much as normal. I am not sure is there any tuning need to be done. Of course this Windows 7 Beta is also running inside my “virtualized” ESX. As far as installation it works exactly like Vista. There is no special drivers require & map a vmimage driver floppy like XP. Will conduct more testing, plan to try out upgrade from XP -> Windows 7. Not sure whether will there be any heart attack happen. Will keep you all posted.
