Since my upgrade to Fusion 4.1 the vmware-vmx takes all my cpu It does this when my Windows 7 VM is up. I check Windows 7 but it's idle (no apps running, little/no CPU on Windows). It's so bad that the load is killing the battery in under 2 hours when it normally takes 8+.
I restarted Fusion and the VM and no change. Sometimes vmware-vmx does decide to use a little less CPU but then suddenly (even when no change on the running Windows 7 VM) it decides to run at max again for a long long time.
In the end I now have to no longer use Fusion as it makes everything else slow and unusable and kills my laptop battery. The previous Fusion version with the same VM didn't do this.
