I have a Mojave VM that I run with pc-q35-5.1

With 7.3 it seems whenever I stop/start the array the machine setting in the XML (below) resets to pc-q35-8.0

Strange that UNRAID would make changes to VM XML surreptitiously.

Is there any way to stop it?

    <type arch='x86_64' machine='pc-q35-5.1'>hvm</type>

    <loader readonly='yes' type='pflash' format='raw'>/mnt/user/system/custom_ovmf/Macinabox_CODE-pure-efi.fd</loader>

    <nvram format='raw'>/etc/libvirt/qemu/nvram/318231bd-841c-44xa-a9f5-389c374b34cd_VARS-pure-efi.fd</nvram>

We added a change to make sure the support version is not decreated. Currently we are running 10.2.2 and these are deprecated. We did have users with 4.x and that support dropped. Qemu 11 is out now and if we update to that 5.x are likely to go.

Hence why 8.0 was selected.

The values are changed when libvirt start. https://github.com/unraid/webgui/pull/2625/changes

Ah, that explains it. Thanks.

Took some time but I got it working with qemu-8.2.
