Hello, I am trying to start a VMM guest based on the example commands in vmctl(8) without luck. The guest is panicking like so: === panic: root filesystem has size 0 ===
Here are the commands I use: === # vmctl create disk.img -s 4.5G vmctl: imagefile created # ls -lh disk.img -rw------- 1 root wheel 4.5G Nov 3 20:24 disk.img # vmctl start "myvm" -m 512M -i 1 -d disk.img -k /bsd -c Connected to /dev/ttyp4 (speed 9600) [ using 1220352 bytes of bsd ELF symbol table ] Copyright (c) 1982, 1986, 1989, 1991, 1993 The Regents of the University of California.
