SOLVED - Help - Sata controller is getting passed when I have VM's enabled

[Mobius71]

I recently upgraded my BIOS to get an nvme working on my system and apparently something changed with iommu so that now a sata controller is getting passed to vfio and messes with the array.  I've tried starting in safe mode, but I cannot edit the VM config.  As soon as I disable VMs with VM manager and reboot, everything else starts and runs as normal.  I can't even set the VM to not auto start as it won't let me save changes to the VM config.  Is there any other way to edit the VM xml when VMs are disabled?

On flash drive on another machine change autostart to no in this file

 

root@GUITest:~# cat /boot/config/disk.cfg
# Generated settings:
startArray="no"

 

Rename /boot/config/vfio-pci.cfg to .old

 

put flash back in server boot.

 

log in

 

open terminal or use console.

mv /usr/local/sbin/qemu /usr/local/sbin/qemu.old

 

start array vm's should not autostart.

 

update VM. 

mv /usr/local/sbin/qemu.old /usr/local/sbin/qemu

 

Dont forget to set autostart in disk settings.

I have created a pr to add a disable function to next release for this type of issue.
