No console to Docker VM - Rancher.

[tommu]

I am trying to launch a Docker VM, rancher. I don't believe it's booting fully. I cannot console to it and it doesn't pick up an IP address from DHCP.
Details!:

After I launch the VM I SSH to FreeNAS, run console as sudo and see ‘connected’. Then hitting enter doesn’t show a rancher login - or anything more. If I leave console connected and stop start the VM I see console messages from the image loading and the stopping on the line

Code:

‘[ 6.367731] Loading compiled-in X.509 certificates’.

Code:

root@freenas:/nonexistent # cu -l /dev/nmdm2B

At the same time I see the notice on console and in /var/log/messages:

I have followed the official documentation here: https://doc.freenas.org/11/vms.html#creating-vms .

Running 11.1-UD.iso. Reinstalled and Now on Nightly train - all in an attempt to fix this issue.

Looking at this some more, this seems to be the most important error:

freenas kernel: pid 6485 (bhyve), uid 0: exited on signal 6

How can I debug / troubleshoot bhyve crashing?

Well thanks for all the help..

For anyone else who might get stuck I fixed this by downgrading to 11.1-RELEASE. Fills one with confidence..
