Since the forum shuffle lost this: I can't boot FC7 with more than about 512MB of memory, even though my host system has plenty (2GB). An older thread suggested the kernel argument mem=nopentium, but that has no effect. Anyone know of a fix or workaround? I'd really like to be able to give the virtual machine a bit more memory.
