Haven't booted VMware in ages, but to day I did and got the message:
VMware Fusion unrecoverable error: (vcpu-0)
NOT_IMPLEMENTED bora/devices/mainmem/mainMemHosted.c:1967
A log file... etc. etc.
I am running Fusion 1.1.1 with Boot Camp on OSX 10.6.8. When it was first installed it was running 10.5.
I didn't do the install and it took me half an hour to figure out how to get the log file, so you'd probably consider me clueless. However, If anyone can help, I'd appreciate it. Be kind.
Log file attached.
