On the VMware VMTN Forums it is reported that VMware Fusion 5.0.x in combination with the latest OS X updates (MacBook Air and MacBook Pro Update 2.0) causes virtual machines to crash. This is reported in the following threads:

The error encountered is:
VMware Fusion has encountered an error and has shut down the virtual machine.
You can simply solve this as mentioned by Darius:
In the meantime, please try this: With your VM powered off, go into the Virtual Machine > Settings, then choose Display, and turn off the Accelerate 3D Graphics option. Then close the Settings window and try to power on your VM.
As a side note, the other option is to wait with running the OS X update.
The update is for 2012 Macbook Pro and Macbook Air devices only and as it is not a security update, I think that it is OK to sit it out a bit and wait until the VMware Fusion team gets a chance to look into this.
