VMWare Workstation on Hardy Heron
On a whim I upgraded my Ubuntu Gutsy install to Hardy Heron yesterday and while most things are working, a key component to allow me to run my billing was not. Since Quickbooks Online only supports IE and iPhone browsers (don't get me started about that genius decision), I run VMWare Workstation with XP as a guest OS.
The upgrade went smoothly but when I tried to open VMWare it kept crashing without loading. A quick scout around and I found this great thread with DirkCoopman's solution. Basically you edit one file in vmmon.tar, tar it back up and re-run vmware-config.pl. I'm running Hardy Heron 8.04 and VMWare Workstation 6.0.3 build-80004.
