At first ssh into the system, it gets a panic. Some basic networking works, including telnet to the ssh port. I've tried giving 256MiB and 512MiB to the FreeBSD guest. The panic happend in both cases. Here is the retyped console output: xn_rxeof: WARNING: response is -1! xn_rxeof: WARNING: response is -1!
