Here’s what worked for me on this hardware. Hopefully this helps others banging their heads against the wall trying to hack away. I’ve been building PCs and hackintoshes for quite some time, so I know my way around opencore a bit. I think the main bios settings are:
IGPU on rather than PEG
virtualization on
Bios Advanced>PCIe/PCI ASPM settings > ASPM disabled
Bar and 4G crypto disabled
hardware:
MSI Z490-A PRO motherboard
11700k CPU
2 MSI Radeon RX 560 AERO ITX 2G Baffin core
SSD hard drive
Old SATA HFS dives to pass through
The MAC Monterrey VM
The Definitive Guide to Running MacOS in Proxmox
Basic details here
PCI Passthrough
nano /etc/default/grub
GRUB_CMDLINE_LINUX_DEFAULT="quiet intel_iommu=on iommu=pt pcie_acs_override=downstream,multifunction nofb nomodeset initcall_blacklist=sysfb_init”
update-grub
Get your GPU ID’s
nano /etc/modprobe.d/vfio.conf
options vfio-pci ids=1002:67ff,1002:aae0 disable_vga=1
Ids=xxxxxxxxx are my particular GPU ids
nano /etc/pve/qemu-server/myVM.conf
Should read this in my case
hostpci1: 0000:01:00,pcie=1
2nd VM in my case
hostpci1: 0000:03:00,pcie=1
Unselect primary on both VM’s key to dual GPU

echo "blacklist radeon" >> /etc/modprobe.d/blacklist.conf
echo "blacklist nouveau" >> /etc/modprobe.d/blacklist.conf
echo "blacklist nvidia" >> /etc/modprobe.d/blacklist.conf
echo "options kvm ignore_msrs=1" > /etc/modprobe.d/kvm.conf
update-initramfs -u
Reboot
pass through hard drives
Find hard drive ID by using one of these methods here:
Passthrough Physical Disk to Virtual Machine (VM)
I followed a guide that used scsi which didn’t work. Virtio was the key here
qm set 100 -virtio2 /dev/disk/by-id/ata-Hitachi_HDS722020ALA330_JK1121YAG4NEGS
Another key hiccup I had to sold was when I added the 2nd GPU My network card ID changed
Here’s what fixed it:
Adding the second GPU changed the network adapter number
ip addr (command)
showed new NAT was enp5s0
nano /etc/network/interfaces
To change both enp3s0 to enp5s0
IGPU on rather than PEG
virtualization on
