Hi, I'm running UNRAID 6.8.3, and have a handful (less than 10) Virtual machines.
Yesterday I upgraded to 6.9 (beta 22) and started noticing issues with a single Windows 2019 VM - it would not start, instead replaced with a blue screen of death stating:
KMODE exception not handled
I restored from a backup of 6.8.3, and was able to rebuild the VM in question.
Since then, I have tried to create a new Windows Server 2019 VM, and it will start, and then freeze. This is similar to what happened yesterday.
In the logs, I can see this:
2020-06-23 12:44:49.256+0000: Domain id=30 is tainted: high-privileges
2020-06-23 12:44:49.256+0000: Domain id=30 is tainted: host-cpu
char device redirected to /dev/pts/5 (label charserial0)
2020-06-23T12:47:45.311413Z qemu-system-x86_64: warning: guest updated active QH
I looked for the error in the last line, and have since run a full parity check (as part of the restore process to 6.8.3), and in addition run both a btrfs balance and btrfs scrub.
I've attached anonymized diagnostics. I'm a first-time UNRAID user, and although using Linux for work, it's not my speciality, so I'm at a bit of a loss where to go from here.
Thanks
