There is a known issue with sleep image corruption when running VMware Fusion on either Mavericks or Yosemite. In my particular case, I am running VMware Fusion 7.1.0 Pro on two computers running Mavericks, and one of them (a mid-2012 MacBook Pro running OS X 10.10.1) consistently exhibits this problem.
Steps to reproduce:
1. Start a virtual machine inside VMware Fusion (in my case, Windows 7 Ultimate 64-bit)
2. Put the computer to sleep while the VM is still running
3. Wait for the computer to enter "deep sleep" (formerly called hibernation
OS X will crash when you attempt to wake it, citing sleep image corruption and failure to wake from sleep. All unsaved data will be lost (less of a problem than in the past, since most apps auto-save state these days, but still serious.)
Workaround: Suspend open VMs and quit VMware Fusion prior to putting the computer to sleep.
This bug has been discussed in other threads, notably Re: Fusion 6.0.2 and OSx Mavericks 10.9.1 - Sleep Wake failure unless I shutdown or suspend my Win7Pro VM before closing lid
While that thread lists another workaround (using pmset to disable deep sleep/hibernation entirely), I've yet to see anything from VMware about a fix for this. Can we get a status update?
