Can't start proxmox VM - error

[HeyWatchOutDude]

Hi,

I followed the guide:
https://www.nicksherlock.com/2021/10/installing-macos-12-monterey-on-proxmox-7/

Sadly I get an error:
kvm: can't apply global ICH9-LPC.acpi-pci-hotplug-with-bridge-support=off: Property 'ICH9-LPC.acpi-pci-hotplug-with-bridge-support' not found
Use of uninitialized value $tpmpid in concatenation (.) or string at /usr/share/perl5/PVE/QemuServer.pm line 5465.

Any idea what is wrong? My Proxmox host has an intel CPU.

This argument is only for QEMU 6.1+. If you're running an out of date QEMU package, omit this argument from your args:

-global ICH9-LPC.acpi-pci-hotplug-with-bridge-support=off
