bhyve Core Dump - help?

[Nick Longo]

I updated to FreeNAS 11 from Freenas 9.10 yesterday. I did an upgrade via an iso image. Everything from my old configuration is up and running.

I'm trying to install my first VM.
My host details
Build FreeNAS-11.0-U1 (aa82cc58d)
Platform AMD FX(tm)-8350 Eight-Core Processor
Memory 32630MB

VM is currently configured:
NIC (Default), VNC (Default), CDROM (ubuntu-server ISO image), Disk (40 GiB volume, AHCI)

Note: the following issue occurs regardless of whether I include a CDROM device or set the Disk or NIC to "VirtIO"

When I start the VM I see messages indicating the creation of the tap and it being up. As soon as a I try and connect via VNC I get a message that byve core dumped on signal 6 (Abort) and the Tap changes state to DOWN.

I changed the VNC setting where I turned OFF the "Wait for Boot". When I do this and try to start the VM I get the following

• Message appears at top of FreeNAS GUI that VM Started
• State though of VM on the VM Tap remains "STOPPED"
• Clicking on the console messages at the bottom of the GUI stops updating/refreshing. Even clicking on it for a bigger screen, it opens but stuck at "Loading"

I have been trying to figure out how to download the symbols to be able to back trace the core dump. I saw a post in here but the link to a bug report is broken. Below is the current output of the core back trace - don't believe it helps much.

Would love some help or insight where to look next.
Thank you

What was the bug number (it is most likely set to private)?

What was the bug number (it is most likely set to private)?

It was this link that didn't work https://bugs.freenas.org/projects/freenas-10/wiki/Debugging
I did create and account and login, says the page is no longer available.

The thread title is "bhyve core dump". Just realized I titled mine largely the same. Swear that was coincidence. I did more searching after I had found that.

Weird that that location had a bhyve thread as Corral didn't use bhyve...

wrt your issue, please create a bug report at bugs.freenas.org that includes a debug (System -> Advanced -> Save Debug) and post the issue number here. Note that your report will be private (not visible to others) until a dev has had a chance to review the debug.

Create bug report 25090 and included a full Debug report output.
