System crashes when booting Linux in bhyve
An OS crash occurs everytime I start a Linux VM in graphical UI like trying Ubuntu 18.04 instead of starting the installer.
Tried latest Centos7, the VM boots to grub boot loader, selecting the install option it takes a bit without showing anything on the VNC screen then the session disconnects and the system is restarting.
I've been running FreeNAS without issues otherwise. My suspicion is that some bios settings are causing this. The /data/crash info file details a MCE panic is occurring.

I have made some more tests. Tried an Ubuntu server minimal for the text installer suspecting a bad video card. Behavior persists but shows in a different way.
Booting the command-line install works but after approximately 10-20 seconds it crashes the VM only and the system remains up. If I retry the system crashes fully and reboots.
I have added a tarball of all of /data/crash. Next step is to do a fresh install of 11.1-U6.3 to see if the crash occurs there as well.

Please close this bug report. The issue was with a core that was buggy. I've disabled core 9 on my CPU from bios and I can run VMs just fine now. This is FreeNAS unrelated. Tested with VMware ESXi that was crashing just the same. Just had to run-crash several times to notice it's the same core raising the MCE.
It is weird that the system was stable before running VMs. Just a point to consider, I guess. I'm really puzzled but this is what you get from buying second-hand xeons from ebay.
From my tests FreeNAS 11.-U6.3 was crashing just the VM but it doesn't matter now. I know that MCE = Hardware issue.
