Hi,

I've just upgraded Fusion to 6.0.1 and all my vm won't start, these screens popped when I try to start any one of them.

Unable to retrieve kernel symbols

Failed to initialize monitor device

Cannot find a valid peer procces to connect to

Version 6.0.1 (1331545)

Any suggestion to fix this problem?
