Obviously OS X 10.9 Mavericks is not yet an officially supported Host/Guest OS as it is not yet a GA Release and if you're using the VMware Fusion Technology Preview 2013 then you should be posting to the VMware Fusion Technology Preview 2013 forum, not here which is for GA Releases.
Other then that the Developers would probably like to see more information so... To help figure out what is what, the best way to provide comprehensive diagnostic information is to use the "Collect Support Information" command from the VMware Fusion (menu bar)> Help > Collect Support Information and then attach the .tgz file it created on your Desktop to a reply post.
Note: Use the "Use advanced editor" link in the upper right corner of the normal reply window to bring up the Advanced Editor where you'll be able to attach files via the Choose File button or Browse button (depending on the Browser) above the Post Message button!
