    Hi,

    I just converted my Fusion VM (Windows 10) to Parallels 11. Everything is fine when my guest has got 2GB RAM. But as I configure the VM to use more RAM (4GB or 8GB) the VM starts only with a black screen. I can see the login screen for a very short time (round about half a second). Then the screen is black. When I reset the guest RAM to 2GB the VM starts normal again. My host has got 16GB RAM.

    Any ideas?

    Best regards,
    Oliver Bollmann
