[vfio-users] OVMF + Os X

Wed Oct 28 18:39:43 UTC 2015

Some progress....

Thanks to root at yoshi.dynu.com.

Booted osx yosemite with chameleon with -vga std and installed yosemite...

Then nvidia web driver install and  passthrough of gtx 970 with vga -none
x-vga parameter... I had to patch kernel for i915 vga arbitration...

Everything works out of the box with some flag in chameleon boot loader...
hdmi_audio, nvda_drv=1,smbios tweaked to MacPro3,1. chameleon installed in
mac os hard disk. Network working with user networking for now...

Working with 2 monitors (Dvi-I to Vga cable, hdmi direct cable) with 1080p
resolution on both. Nvidia acceleration working.

Experimenting with usb controller passthrough

My command line :

sudo qemu-system-x86_64 -enable-kvm -M q35 -m 4G -cpu
core2duo,hv_time,hv_relaxed,hv_vapic,hv_spinlocks=0x1fff,kvm=off,hv_vendor_id=badapple
 -smp 2,sockets=1,cores=2,threads=1  \
-drive file=/dev/mapper/vgData-logicMac,id=disco,format=raw \
-device
ioh3420,bus=pcie.0,addr=1c.0,multifunction=on,port=1,chassis=1,id=root.1 \
-device
vfio-pci,host=01:00.0,bus=root.1,addr=00.0,multifunction=on,x-vga=on \
-device vfio-pci,host=01:00.1,bus=root.1,addr=00.1 \
-kernel /mnt/archData/virtualMisc/chameleon_svn2510_boot \
-device isa-applesmc,osk="findityourself" \
-device i82801b11-bridge,id=pci.1,bus=pcie.0,addr=0x1e \
-device pci-bridge,chassis_nr=2,id=pci.2,bus=pci.1,addr=0x1 \
-device piix3-usb-uhci,id=usb,bus=pci.2,addr=0x1 \
-netdev user,id=mynet0,net=192.168.76.0/24,dhcpstart=192.168.76.9 -device
e1000-82545em,mac=DE:AD:BE:EF:AD:3c,netdev=mynet0,id=nic1 \
-smbios type=2 -vga none -device usb-kbd -device usb-mouse -boot d  -vnc :2
-k it

Some questions :

1)Is it possibile to manage this on libvirt? vga none doesn't seem an
acceptable value when editing with virsh. If i remove video tag, next
opening cirrus is there. I would like to use also virtual existing
networks... Libvirt is opening tap device when booting a vm...

2)Progress with OVMF and i440fx with Mac OS? this article
http://blog.will3942.com/qemu-osx-update states that currently OVMF doesn't
support OSX. Would like to avoid i915 and loss of DRI on host...

Thanks in advance

>>> I solved this by assigning an own partition for the VM. It would be

>>> if you like to i can post my config later
