Then you could pass 1 to osx and 1 to windows. So you dont  need to shutdown either OS you could have them running at the same time. So your original question would be pointless at that point...

 

No because I would want as much cpu power for the win10 gaming vm. Closing the macos vm would free up resources for gaming. Maybe I could use both GPUs for the gaming vm too?

same rules apply then you would have to shutdown osx before windows could take over using the cards. I don't know how to me more clear. You cant suspend a VM that is using PCI pass-through it must be shutdown.

You are being clear. But what isnt is why this is the case. It seems like you should be able to "release" a gpu which a saved VM was using.

Can you unplug a gpu from a running machine and it be happy? no you cant. PCI is not a hot swap-able device standard. So you start the VM it initializes the GPU talks to it's firmware loads the drivers ect. Then you save the VM's state. At this point you have a copy of the VM's ram saved to disk but not it's Vram. Now you load up windows it initialized the GPU and erased the OS X data from it's VRAM. When you try to relaunch the VM of OS X in the saved state it will not re-initalize the GPU it will asume it was still plugged in because from it's view it was never actually shut down the memory of the VM was just staved for later. This is why you need to start up the VM and cant save it's state.

The previously patched clover in this thread works for me. Don't know whats wrong with the newer patched clover? But there was one more with same issue that I have with choppy sound for newer patched clover.

I too am running on unRAID and was experiencing audio stuttering on a number of VMs but not macOS using the patched Clover 3578.  After installing email4nickp's patched Clover 3923 my unRAID Sierra VM started to experience audio issues similar to what Peter_sm is experiencing.  The solution that worked for me was to isolate and assign CPUs to the VM.  Alter your syslinux configuration to include the cpus you'd like to isolate

  append isolcpus=2,3 initrd=/bzroot

and add an emulator pin to you're VM configuration

  <cputune>
    <vcpupin vcpu='0' cpuset='2'/>
    <vcpupin vcpu='1' cpuset='3'/>
    <emulatorpin cpuset='0'/>
  </cputune>

Currently running patched Clover 3923 without issue after applying the above.

Hi, Thanks, it seems to work!

I have these settings in unRAID

cpu 0 / 8	
cpu 1 / 9	
cpu 2 / 10	
cpu 3 / 11	
cpu 4 / 12	
cpu 5 / 13	
cpu 6 / 14	
cpu 7 / 15

 append isolcpus=4-6,12-14 vfio.pci.ids=10de:11c0,10de:0e0b,1002:6779,1002:aa98,8086:3c08 initrd=/bzroot

  <vcpu placement='static'>6</vcpu>
  <cputune>
    <vcpupin vcpu='0' cpuset='4'/>
    <vcpupin vcpu='1' cpuset='5'/>
    <vcpupin vcpu='2' cpuset='6'/>
    <vcpupin vcpu='3' cpuset='12'/>
    <vcpupin vcpu='4' cpuset='13'/>
    <vcpupin vcpu='5' cpuset='14'/>
  </cputune>

but what should I set for this line ?

<emulatorpin cpuset='?'/>

With the pinning and updated syslinux with isolcpus I don't need a patched Clover :-) all is working find including HDMI sound :-) :-) running Clover_v2.3k_r3969

 

//Peter

Peter, I'm still having issues with CPU speed on stock Clover r3961 installed. Was previous using gridrunner's EFI from his YouTube guide for UnRAID which worked fine, but would really like to update Clover with the hope FileVault2 will run. isolcpus + pinning (vcpu and emulatorpin) still has the same result with Clover's QEMU flag disabled (superspeed) and QEMU flag enabled (1/4 speed).

 

Where did you get r3969? I can't find it anywhere.

 

Would you be willing to share your domain.xml, syslinux, and/or config.plist? Are you still on r3969? Thanks a ton.

Hey guys I'm running two copies of OS X on my computer. One is running OS X server and the other is using PCI passthrough as a desktop workstation. Anyways when playing with with OS X server I figured out that you don't need the flags

-device usb-kbd -device usb-mouse

Instead use 

QemuUSBTablet1011.kext

VoodooPS2Controller.kext

 

This way you can use the native KVM keyboard and mouse. I just dropped the kexts into my clover folder.

 

mouse&keyboard.zip

Checking in after a few months. I attempted to upgrade to Sierra by performing a clean install in the same manner I did for El Capitan. Clover latest has fixed issue with Penryn CPU type. However, I did experience the GUI slowdown with Qemu CPU choice in Clover. The patched clover that was posted from the mega link worked for me. Will update the post with my specs in a bit.

Are you able to use host CPU settings with the latest clover build? I've been putting off updating for a while now!

I'm still not able to use host setting. Out of curiosity why do you care? I don't think it even makes a difference for performance of OSX.

I'd like to get it running as natively as possible. More to satisfy my OCD than anything else! I can't help but feel using a bodged version of clover with an antiquated guest CPU type is a bit hackish.

Run the following:

 

sysctl -a | grep machdep.features

 

Compare to your host CPU and let me know if there is a difference.

Hey guys. It's been a while. Other reported that Qemu-CPus are fixed with current Clover... well at least not for me :/

 

However you can achieve nice benchmark scores with it :) : https://browser.geekbench.com/v4/cpu/compare/1546170?baseline=1546422

 

So i applied the patches again (since nobody @ the source forge ticket reacted and clover is too big of a mess so i won't maintain a for myself):

 

https://p-sol.de/claudia/index.php/s/ZPsZsJVi8N8ro64

 

Works fine for me, however only with Penryn vCPU. While my last fix worked for Westmere / Sandybridge / etc as well this one for me only works with Penryn (and core2duo, etc of course, but who wants that ?? ;) )

 

If i find the time i might again dig deeper into it and try to get it fixed without workaround :P

 

 

tested on X58 + X5650 and C602 + e5 2660

Revisiting this thread. Currently this is STILL my day to day workstation. I use it as I would use my Apple laptop. Experience has been optimal. Recently I updated to Sierra and had a problem with sound. I did the following:

 

Success: 

 

1. Updated Arch Kernel. I noticed that the ALS downstream flag was not supported in my kernel. I then went to AUR and grabbed the vfio kernel and installed from there. Once complete, I noticed all IOMMU groups were seperated for the most part.

2. Updated virtual machine command to use ONLY vfio. This is now solid.

3. Updated to latest sierra. GTX 970 still working like a champ. 

 

Pending:

 

1. Sound is currently broken. I have a USB DAC so this isn;'t really a problem, but I would like to get optical out working for my ALC1150 chipset. Any pointers would be appreciated. 

 

This is an extremely good setup. My clover version from SVN is still working flawlessly.

I don't have any similar setup like yours, but did you give this a try?
