You may want to check out this KB from VMware in reference to this issue.
I was recently setting up a Windows 7 image for our VMware View environment and the overall process was very quick and simple compared to other OSes due to the simple, fast installation of Windows 7. However, when I first attempted to connect to a View desktop using PCoIP, I was presented with a blank or black screen that in a minute just closed seemingly refusing the connection. The console of the virtual desktop appeared to logon with the specified user but the remote session was not working. Quickly, I remembered setting up Windows 7 in another View environment and recalled the need to change the video driver. Here is a quick “how to” that will get you up and running with Windows 7 in VMware View using PC-over-IP. NOTE: Windows 7 is still “experimental” in VMware View.
Right-click Computer then click Manage.
In Device Manager, expand Display adapters, right-click VMware SVGA 3D, click Update Driver Software…
Click Browse my computer for driver software
Click Let me pick from a list…
Click Have Disk…
Browse to C:\Program Files\Common Files\VMware\Drivers\video and click OK.
Choose VMware SVGA II and click Next.
The driver is installing…
Done. Click Close and restart Windows.
Finally, it is a good idea to increase the amount of video memory by editing the virtual machine settings. 40 MB seems to be a recommended amount floating around the blogosphere.
