since upgrading to 6.9 i'm getting this error every time I start a mac VM with GPU passthrough:

 

warning: host doesn't support requested feature: CPUID.01H:ECX.pcid

 

It works fine when I use VNC, and all other OS work with GPU passthrough.

Hi, I think this isn't your issue, it's not a stopper, it's a warning that shouldn't prevent your vm from running.

This is the full log:

It works fine with VNC only
It doesn't work at all with GPU only
But with VNC and GPU, VNC stays on apple logo and GPU shows secondary screen.

There are no issue in qemu/kvm. You need to provide clover/opencore log.

For opencore use a debug version and change Target to 83 in config.plist, then upload the log generated in the EFI folder. 

That warnings will go away if you delete +pcid from your cpu arguments.

Is your gpu compatible with the version of mac os you are using?

Did you ever manage to get it work with older versions with gpu passed through?

How can I access the log?

Following instructions refer to opencore, no idea for clover

Easiest way:

1- Backup your bootloader file (/mnt/user/domains/MacinaboxCatalina/Clover.qcow2), copy it somewhere in case of issues, so you can restore the image.

2- Since it works with vnc, set up the vm with vnc; once booted into mac os mount the efi image Clover.qcow2 (use opencore configurator, clover configurator, any software able to mount efi partitions, or terminal).

3- Download the latest stable debug version of opencore (0.6.7):

https://github.com/acidanthera/OpenCorePkg/releases/download/0.6.7/OpenCore-0.6.7-DEBUG.zip

4- Extract the archive and replace the files on your mounted efi with extracted ones.

5- Open config.plist, search for "Target" and change it to 83.

6- Shutdown the vm, configure your gpu passthrough, start the vm.

7- After it freezes, force shutdown the vm, reconfigure it with vnc.

8- Start again the vm, mount again the efi image Clover.qcow2 (use opencore configurator, clover configurator, any software able to mount efi partitions, or terminal), go to EFI folder and you will find 2 logs (the "failed one" and the current one).

9- Upload the failed log.

on step 8 I get this:

 

Did you setup the bootloader according to your needs?Or you just copied/pasted?

The error refers to missing Hfs driver, VBoxHfs.efi.

You are missing that file in EFI/OC/Drivers

Edited March 21, 20215 yr by ghost82

I replaced the files as per your instructions

ok it seems you used an older version of opencore?

Open your config.plist and replace VboxHfs.efi with OpenHfsPlus.efi

Make sue you have the file OpenHfsPlus.efi in /EFI/OC/Drivers

You need to check what changed in the config.plist from your older version to the new one, several keys were added and removed.

It's working now.

When I first set up the server I created a custom GPU ROM with higher fan speeds.  It worked fine so didn't suspect that as the culprit.  I changed back to the original ROM and it works fine now.
