vmm: panic: root filesystem has size 0

Patrik Lundin-3
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)

Output of vmd -dvvv when this happens:
===
# vmd -dvvv

i8253_reset: unsupported counter mode 0xe
vmd: unknown exit reason 48
===

I notice the man-page runs "vmctl create" as an unspecified unprivileged
user so I have tried doing "chown _vmd:_vmd disk.img", placing disk.img
in "/home/vm" also owned by _vmd. I still get the same panic however.

Complete dmesg of the host system in case it is interesting:

You actually have to install OpenBSD into that image.  Try -k /bsd.rd first.
