Bhyve windows VMs are unstable.

[Psychoteur]

Hello,
since the latest version of freenas 11.2. All Windows VMs crash (Kernel power error). I've got no error in the logs.
I've got a PiHole vm that is totally fine running without any disruption.

So where to start ? What information should I pull ?
I think it's a memory management problem.

OS Version:
FreeNAS-11.2-RELEASE
(Build Date: Dec 5, 2018 21:28)

Processor:
Intel(R) Xeon(R) CPU D-1521 @ 2.40GHz (8 cores)

Memory:
64 GiB

Storage:
5*3TiB in Z2 and 7TiB free.

and I've got 5 jails running: plex, mariaDB, all-in-one (jackett-sonarr-radarr), transmission, JDownloader.

Thanks.

you arent alone... I've been going nuts trying to get my Windowws VMs running. I have tried fresh installations of Windows Server 2012 R2 and Windows Server 2016. I can get them installed but they appear to not stay running for more than a few hours before they are unresponsive.

Currently contains my debugs, so they might have it set to private, but my DockerVM is 'dying' every couple of hours (and sometimes, comes back, sometimes not) - it also seemed to impact SMB performance (or SMB performance impacted it - can't be sure of t his one yet)

Definitely seeing VM instability though - but it was a RancherStyle VM and 1.4.1 not 1.4.2

Worth letting you guys know though.
