I do not believe that VMware has provided a VMware Fusion release that officially supports Mac OS X Lion as a Host or Guest however I've had no problems running VMware Fusion 3.1.3 on the Developer GM of Lion.
I've had some issues with running VMWare. It puts the system to a halt. I've noticed that this happens when I'm running Safari. I've also noticed that when I turn off extensions in Safari, then things are a bit smoother, but I'm still testing this to see if that's really it or not.
Macbook 5,1 Unibody
Core 2 Duo 2.4Ghz
OS X Lion - clean install from USB media (also had same problem when upgrading from SL so I don't think this is an issue)
7200 RPM HD
VMWare Fusion 3.1.3
- Running Ubuntu - not too bad, only a little slower
- Running Windows 2000 or Windows 7 - computer goes to a halt, beachball and Safari stops responding. Mail usually runs, but very slow. Switching between desktops can take upwards of 20 seconds. Under SL I never had these issues.
When running Fusion in full screen mode, it doesn't move to it's own space. Therefore it completely covers up the Desktop. 3-finger swipe does not allow me to see the desktop although I can switch between Fusion, Mail, Safari, etc. running in full-screen mode. Any ideas? I hate to have to drop out of full-screen mode every time I want to see files on my desktop.

In mission control, drag your VM's window into it's own space. There is a + sign in the top right corner of mission control that is a drop location for windows. Once you have given it its own space, then you can full screen it and do 3-finger swipe between them.
Just to close out this discussion. No problems here. Thanks everyone who answered. And thanks to the VMware Fusion team for posting a statement to the blog. It goes a long way to give confidence.
