Yosemite causes VmWare to malfunction

After my Yosemite upgrade, my VmWare fusion 5 displays the following error "Could not open /dev/vmmon: No such file or directory" when I try to run any of the virtual machines.


I ran "ls -ld /dev /dev/vmmon" and it shows that the there is no such file or directory.


Appreciate if someone can assist in this matter.


Thanks & regards,

Are you sure your problem is solved?


I had Fusion 6; I was told to upgrade to 7 and everything will be magically fixed because Fusion 7 is supposedly written for Yosemite! WRONG! $80 later I'm still having the same exact issue. I now have weird flickering problems with my KUbuntu guest OS. But that isn't the worst thing.


I'm having all sort of networking related problems with VMware Fusion 7 (all updates installed as of today) and Yosemite. For example Yosemite, or VMware somehow interfere with my time machine incremental hourly backups to my 3 terabyte Apple Airport Time Capsule if Fusion is running.

I kill Fusion; reboot the system, and everything seems to work fine.


I also can't access my NAS from OSX (connected to the time capsule via USB) if fusion is running. Notice I'm not saying Can't access it from a guest OS on fusion; It's messing up my HOST networking. So much sandboxing the fusion app.


Are your problems really resolved or did you get suckered like I did? I was really happy for a couple of months until I found out backups were silently messing up in the background.


If you use Time Machine for backups with Fusion 7 and Yosemite watch out. It will suddenly fail.
