Does this only happen when you pass something through? Then it might be connected with the KVM halt_poll_ns parameter. In newer kernels this value has been above 400.000 which creates CPU load with different guests. In most recent kernels this is fixed (at least for windows guest) by setting it to 400.000, but my linux guest needs a value of 100.000.

Look at /sys/module/kvm/parameters/halt_poll_ns on your host and try to lower it to 400.000 or 100.000 and then set it permanently via an modprobe.d entry:

options kvm halt_poll_ns=100000

I've got another problem:

I've managed to boot and install El Capitan 10.11.5 with libvirtd/virt-manager and minimal xml edits, partially following this guide: https://gist.github.com/gordonturner/2a2e5ecde5e7860b52e2. But as soon as I try to pass through my GPU, after Clover tries to boot OSX, I can either see the pluses '++++++' on the GPU-connected display or the frozen white Apple Logo (when booting without the '-v'-Paramter), but nothing else. In case of the pluses (verbose mode) with most tests the display turns off / shows no signal after several seconds.

BUT I can connect via VNC to the guest.

 

What I tested:

  • GT 630 with DVI, HDMI(-DVI-Adapter), VGA-out / 750Ti with DVI-out
  • nv_disabled=1 / nv_disabled=1 & nvda_drv=1 / nvda_drv=1 (nvidia Web drivers installed without passed GPU from spice/vnc-connection)
  • with / without nvidia injection
  • my libvirtd xml / qemu commands that others have successfully used
  • different resolutions set in clover. After increasing it above 1280x1024, clover still grew up to 1920x1200, but within the VNC-connection I only have 1280x1024.
  • single <loader> line (necessary to boot at all)

interesting log entries: nvda::rmstart failed followed by multiple NVDA,Display-A: Not usable

 

I have no idea if this is a virtualization problem or clover/nvidia related.

I don't have any experience with newer nvidia cards, but I think any nvidia cards after 500 series (like 630 or 750ti) you have to:

- disable nvidia injection and then

- initially boot with "nv_disable=1" flag (with os x drivers)

- after that initial boot install nvidia drivers and remove that flag and reboot, hence you are now using nvidia drivers, which supports newer series cards.

Not in my case, using ubuntu16 1-3% cpu load in guest and host. What I also see is that the "memory usage" graphic in virt-manager is incorrect, showing always as full.

Apart from this, I got the same results in cinebench in the vm and  as a "native hackintosh" (i5 4590 and ATI 5750)

Could you please post this picture to imgur or something?

To those who got a working OS X vm with or without GPU passthrough:

how much CPU is used on the host side when the OSX vm is idling?

 

My host uses 15-20% CPU when the OSX vm is idling (1-2% CPU usage in the guest), and I wonder if it's normal...

Be sure to compare the right values. Linux process CPU% can go beyond 100% with multiple cores. Idling in Mac OS X gives me 1-2% in OSX and on the Linux host, while the qemu process is at about 10% (4 core ... 8 with HyperThreading).

 

 

Regarding audio issues: My opinion is, that the virtualized Mac is not suitable for audio editing with low latency stuff. Spare yourself the trouble and use a USB audio adapter, if you can't get HDMI/on-board sound working. 

 

Regarding memory usage: AFAIK the VM will use the complete assigned memory when booting as soon as PCI Passthrough is used (at least that was the case when I started researching this - late 2014).

Thanks for this info how it should work. Unfortunatly, as soon as the nvidia card is passed through I've got no more output after these pluses. Even with the nv_disable=1 flag. I've also tried waschbenzins clover-debug-test.dd image to boot, same behaviour. The verbose output that isn't displayed on the monitor (but sent via serial console) is:

I can't find any information why my card is rejected as output so early in the booting process. Its EFI gop showed no problems elsewhere.

 

EDIT 2: Problem found: latest ovmf compiled from git (arch AUR), using ovmf_code_x64.bin. Older, downloaded OVMF-pure-efi.fd works. Have to try different other versions.

@KillerKelvUK

So i tried using virsh to make the network

 

I used the virsh net-define command and made the following

<network>
  <name>default</name>
  <uuid>SomeUUID</uuid>
  <forward mode='nat'/>
  <bridge name='virbr0' stp='on' delay='0'/>
  <mac address='SomeMAC'/>
  <ip address='192.168.122.1' netmask='255.255.255.0'>
    <dhcp>
      <range start='192.168.122.2' end='192.168.122.254'/>
    </dhcp>
  </ip>
</network>

The i attached it to the VM like so:

    <interface type='bridge'>
      <mac address='SomeMac'/>
      <source bridge='virbr0'/>
      <model type='e1000-82545em'/>
      <address type='pci' domain='0x0000' bus='0x02' slot='0x01' function='0x0'/>
    </interface>

The i try to start the network, with

 

virsh net-start default

error: Failed to start network default
error: error creating bridge interface virbr0: Operation not permitted
sudo !! (run previous command as root)
Network default started
 
After this i try to start the VM
 
Error starting domain: internal error: /usr/lib/qemu/qemu-bridge-helper --br=virbr0 --fd=24: failed to communicate with bridge helper: Transport endpoint is not connected
stderr=failed to parse default acl file `/etc/qemu/bridge.conf'
 
Note: I am on WIFI, using NetworkManager and gnome3

Could you please share the details of your setup? (qemu/libvirt config, bootloader used, etc...)

 

Does this only happen when you pass something through? Then it might be connected with the KVM halt_poll_ns parameter. In newer kernels this value has been above 400.000 which creates CPU load with different guests. In most recent kernels this is fixed (at least for windows guest) by setting it to 400.000, but my linux guest needs a value of 100.000.

Yes it also happens without GPU passthrough.

 

Be sure to compare the right values. Linux process CPU% can go beyond 100% with multiple cores. Idling in Mac OS X gives me 1-2% in OSX and on the Linux host, while the qemu process is at about 10% (4 core ... 8 with HyperThreading).

The power draw increases by at least 15W and never go below when my osx vm is running. Any other vm (Linux or Windows) does not increase the power draw when idle.

@Maclarentosh.

 

Little confused by your last post bud, your original post was to connect your vm to a network bridge (also called a Routed Mode by Libvirt) however your last post xml shows you aren't bridging but instead using Network Address Translation (NAT).  (http://wiki.libvirt.org/page/VirtualNetworking)

 

Do you want your vm's to be allocated an IP address in the same subnet as your physical devices on the same LAN or something different?

 

If you are using virsh for the network and virt-manager for the guest config and start/stop etc I'd suggest you simplify this and just use virt-manager for everything i.e. create the networks using virt-manager instead of virsh.  The only complication here I can see is that you are using a wifi adapter, was it you who posted here a while back struggling to get bridging working with a wifi adapter?  The wifi element may mean you have to manually configured a routed bridge (if that's what you want) using either systemd or the /etc/network/interface script...not something I've done with wifi sorry but will do a little digging if this is what you are trying to get working?

Would this work with the host chipset being a hd 4000 and passthough as well?

Well I'm using the on chip video from my Intel cpu for host video only. If you want to passthrough your hosts primary gfx to a guest then this comes with no end of tech challenges. Suggest you solve these with a Linux or Windows guest first before tackling that with OS X virtualisation.

I have one PCI-E nVIDIA GPU and one onboard VGA. Is it possible to share the nVIDIA GPU between two or more guests: OS X El Capitan 10.11.x and Ubuntu, Windows?

 

I'm thinking of running 16.04 Desktop / Server as the host with KVM/qemu or Xen and then virtualize:

 

1) OS X for Adobe apps, CAD, software development, potential light gaming (League of Legends, Starcraft) so latency would be an issue and

2) Ubuntu for machine learning (GPU), software development, compiling and

3) Windows for certain apps that only work on Windows.

Yes but unless your GFX is a Quattro or similar then you can only pass the gfx card to one guest at a time.

 

I have 2 guests (virtual machines) configured, one OS X and one Windows and they both have my GTX passed thru however I can't run both guests at the same time. The Quattro cards and similar have the ability to share their resources across multiple guests at the same time so you could run all your guests at one using a card like this. Or you could purchase more GFX cards and dedicate a card per guest but obviously that's got its own downsides.

I finally figured out where the high host CPU load was coming from:

the emulated USB controller.

Removing all USB controllers and devices from the qemu parameters reduced the host load to 1-3% when the guest is idle.

I have been watching this thread since its begining and decided this weekend to plunge and try it myself. Surprisingly that was worked on the first try! So thanks to all who participated in this thread!

 

Well, it's not completely working. I cannot get sound out of my Nvidia gpu HDMI output. I'm  on Yosemite.

 

I searched and found audio_cloverHDMI (https://github.com/toleda/audio_CloverHDMI) but could not make it work because I could not find the right HDMI audio ssdt (https://github.com/toleda/audio_hdmi_amd-nvidia) for the

IOReg display device name I have.

Do any of you had better luck with this option or another?

 

Thanks

Hey, I have working HDMI audio from my nVidia GTX 970 using a clover injected kext.

 

It's ages since I found the actual source, the top Google link now is to a site/forum that's frowned upon here due to their open policies or lack there off so I won't provide a direct link. So I offer you 2 options...1) the kext that needs to be injected by clover at boot is named 'hdmiaudio-1.0.dmg', a google on that alone should get you running. Option 2), Google search for "Clover HDMI audio for NVIDIA & AMD cards. Easy way." and choose the top hit :)

Indeed, so easy! Thanks KillerKelvUK!

I have another issue and -- from my point of view -- a big one. The whole point of this Mac vm was for me to do photo editing with Lightroom, but I just noticed that I'm not able to passtrough my photo camera.

 

I was able to passthrough usb devices of my mouse, keyboard and even bluetooth dongle, but not the photo camera. I'm puzzled. I start the vm with the camera powered on.

 

Any clue?

Thanks again.

 

P.S. Passing through the whole usb controller is not really an option as it seems all my system usb ports are on the same controller.

How are you managing the guest...qemu command line or libvirt?  Looking for log files that may help narrow this down...typically if you have usb passthrough working on some devices and not others I'd say maybe you have a permissions conflict on the /dev/xxx node meaning qemu can't get access.  If this is the case there usually some semi helpful log entries which for me would be in /var/libvirt/qemu/name_of_guest.

Hi I am restoring my problem with jumpy cursor in OS X. My previous thread was deleted because of insanelymac db problems. 

 

The problem is that, when passing separated usb devices to OSX my mouse cursor is erratic and jumps all over the screen under high cpu load. I tried to pass through whole usb controller, but I am not able to do it. I am not using virsh just qemu command. Could someone post guide how to passthrough whole usb controller to VM? Thanks. Also is there any way how to find out which usb devices uses which controller? Here is lspci -nn | grep USB command result

Hope that helps. You will lose the ability to control linux with your usb devices until you power down the vm! I use a PS2 keyboard for emergencies. You also cannot use any usb devices connected to that controller in any other vm. You might want to try a secondary add-in usb controller for this (but my luck with that was rather limited - due to hardware incompatibilities).

 

Off-Topic: Anyone who want to expand their qemu experience with another operation system: Try Remix OS to get Android on your PC. Works fine in qemu for me (32-bit version without uefi and without gpu passthrough). I used the installer to create a usb installer. Dumped it using dd and now I'm running off that image. You can use a virtual audio device ( -soundhw es1370 ... thanks to reddit for that).

Thanks,

 

but I found very interesting thing. This erratic mouse movemenet, only occurs with my Logitech G400 mouse. Yesterday I tried magic mouse via passthroughed bluetooth dongle and it worked like a charm. But the real problem is, that Logitech mouse is working fine in other hackintoshes (which runs on bare metal, not in qemu)

Shot in the dark ---#> Possible that your G400 is using an interrupt that's operating on a unsympathetic CPU core to that which you have pinned to your guest and the USB bt dongle isn't, take a look at the mapping in /proc/interrupts.  Like I said shot in the dark.

Has anyone here got a newer CPU working? I'm on the i7-4790.

 

-cpu host gets stuck with a bunch of + signs. I've tried: FSB of 100 MHz, 200 MHz (clover detected), 1 GHz, 1.2 GHz. Tried combinations of KernelPm, AsusWhateverPM, Haswell-E Kernel and NullCPUPM.

 

-cpu core2duo works OOTB, but doesn't detect the correct FSB. It detects 1.2 GHz. Works fine, but I'm not really happy with it, because Sierra.

 

-cpu Penryn is slow (by about 5x I think), both with a manual FSB of 100 MHz and 1200 MHz.

 

-cpu IvyBridge has the same results as host.

 

Another problem I'm having is that the e1000-82545em only reports a speed of 10 Mbps when booting, not sure if that is cosmetic at this point.

 

Here's my command so far:

sudo qemu-system-x86_64 \
\
-rtc clock=vm,base=2016-01-01T16:01:21 \
\
-name KVM-OSX \

\
-drive file=/media/hameer/Storage/Hackintosh/KVM/MainDisk.dd,if=none,media=disk,id=drive-sata0-0-0,format=raw \
-device ide-hd,bus=sata0.0,drive=drive-sata0-0-0,id=sata0-0-0 \
\
-usb \
-device usb-mouse \
-device usb-kbd \
-serial stdio \
-device qxl-vga,id=video0,ram_size=67108864,vram_size=67108864,vgamem_mb=16

Edit: Don't know if this is relevant but I get this when I "Exit Clover" on every single CPU, including core2duo, but shutting down/restarting works fine as long as OS X boots.

Edit 2: The 10 Mbps thing seems cosmetic. Copied something over samba and it seemed to go as fast as the HDD would allow.
