I have been using Fusion for 2 weeks now the high CPU load is a slight concern. Yesterday I upgraded to 3.0.1 upon restarting this morning my Windows 7 was consuming lots of CPU load, the cause as you can see below is the VMwareuser which should have been fixed in 3.0.1
I had to restart my Windows 7 to bring the CPU load back down to normal, hopefully this won't happen again.
In MBP I could boot to use the 64 bit kernel from this I have to check if firmware supports it by entering below in Terminal
ioreg -l -p IODeviceTree | grep firmware-abi
If the return is 'EFI64' then I just need to boot by pressing the '6' and '4' keys together while starting up.
After trying Windows 7 x64 bit with Office 2010 x64 bit public beta I just couldn't see much difference in performance. There is also printer driver support problem if I run Windows 7 x64 in the office. However it looks like that memory utilization is slightly better in OS X running 64 bit.
Now if you want to boot into x64 all the time you could modify this file
/Library/Preferences/SystemConfiguration/com.apple.Boot.plist
to insert this between 'string' tags
arch=x86_64
Before you do the above first of all you'll need to gain root privilege into your MBP. Haven't done this before here's the way.
I have decided on Fusion 3 and purchased a boxset from a retail store. I have been playing around with it for a while now, am still learning. Obviously with VM I could do all sort of silly things such as
I have also experienced serious problem with the working copy of Windows 7 32 bit which I need during the day due the my dumb idea of storing the pst files of outlook on a desktop folder of OS X which is a bad idea. That crashed the OS I need for work which I had to reinstall again.
A feature that I overlooked is the AutoProtect which enables me to roll back to a earlier healthy version of the OS, see below
Apparently this doesn't consume too much of disk space. I'm now so efficient in reinstalling OS, connecting to the office network, installing printer drivers, mapping network drives .... etc but I don't really want to do this over and over again.
(Edited: this roll back feature turns out to be a bad idea, it took more than 30 minutes on my MBP and while it's doing that the guest OS is basically not functional and I can't even run a broswer on OS X)
