I have the same/similar black screen problem except the Guest OS is Windows 7 using Parallels 10 (latest build) and the host OS is Yosemite (10.10). After booting into the guest OS I can see the desktop for a second and then the screen goes black. I can see the cursor but it's on a black screen. If I use mission control to "back out" of the full screen VM I can see the miniature preview of the desktop for the guest OS but again... after selecting Parallels the guest OS screen goes black again. The problem appears to be minimized by disabling hardware acceleration. However, I use Solidworks in Parallels and it's effectively unusable with software acceleration only because of painfully slow refresh rate of the screen when tumbling even a simple model. And of course the VM is unusable now if the hardware acceleration is turned on. So both are unusable.
Is there a fix for this?
I'm using a core i7 MB Air with 8GB of ram, 1.5GB of dynamic video ram and the Intel HD 5000 graphics card. (same hardware configuration as the new top of the line mini announced today)
