I have been happily using a Windows 7 Pro guest VM for may weeks under Fusion 5. Unity worked without issue, clipboards shared between guest and host (and vice versa). All was well with this VM under Fusion 5.
Over the weekend, I backed up my Macbook and installed Fusion 6. I upgraded the Win7 VM and installed the new VMWare tools. After restarting, I noticed that the VMWareTools Icon did not appear in the Task Bar "tray." I uninstalled VMWare Tools, rebooted, reinstalled the Tools, and rebooted. This time, the VMWare Tools icon appeared in the tray.
However, when I tried to switch to Unity view, the VM display window disappeared for 5-10 second, then reappeared without switching into Unity mode. At this point, the VMWare Tools icon also disappeared from the tray.
The clipboard sharing is not working, either from guest to host or from host to guest.
Finally, when this Windows 7 VM is running, I am experiencing performance issues in other programs running on the host. In some cases, normally smooth animations are "stuttering" and skipping. This goes away when I shutdown Fusion, and was NEVER and issue with Fusion 5, even running multiple VMs concurrently. The host is a Macbook Pro with 8 GB RAM. The Windows 7 guest is allocated 2 GB and 1 virtual core.
I am sorely tempted to roll everything back to Fusion 5, as Fusion 6 doesn't seem ready for prime time. Would appreciate any feedback or info on others experiencing similar issues.
