I have 32gb RAM and 9x4gb in raidz2. I tried to setup Windows 10 in a VM with 2gb RAM and it kept freezing/aborting. This is the only VM on the machine. The only other thing on the machine is another jail where I installed transmission, plex, and flexget. So I don't think I am running out of memory but I could be wrong.
There is no spoon.
