[vfio-users] OVMF + Os X

[root at yoshi.dynu.com]

Hi.

I am running a OS X VM with VGA-Passthrough just fine.

using seabios and Q35 machine and latest Clover bootloader (start with 
the iso, it will detect the correct settings). Interesting thing is: 
Performance is even better compared to 'bare metal' hackintosh.

If i am correct there is no way to run OS X completely headless. you 
could however use emulated VGA and then connect to the machine via VNC 
but performance will be really bad.

People running real MacMinis headless also need to use dummy-adapters 
which trick the machine into thinking there is a monitor attached.

Problems i encountered:

when just assigning an image as a hdd you might run into a freeze at 
boot of the VM, qemu will tell you that the I/O thread spun for 1000 
iterations. Seems to be a problem between OS X and the emulated 
SATA-Controller.

I solved this by assigning an own partition for the VM. It would be even 
better to passthrough a complete SATA-controller but mine does not like 
that :)

if you like to i can post my config later

Cheers
