Adding vfio-users mailing list in case anyone knows what I may be doing 
wrong.

Thanks!

You need a time machine because the thing you're trying to do hasn't
been implemented yet, it's under discussion upstream.  Thanks,

Re: [Qemu-discuss] SunOS 4.1.4 on Qemu 2.10.0 on Mac OS X 10.12.6 on mid 2012 Intel MBP w/16GB RAM

[Will Senn]

After much trial and error and after being reenergized by Mike's 
confirmation that it wasn't hopeless, I figured out what the problem was 
- apparently unselecting the ethernet device before setting it causes 
the install to misconfigure the nic and this causes the rpc problem 
during boot. Instead, just click x to select le0 even though it is 
already selected and then provide your ip address. With 'ansi' chosen as 
the terminal, there are some weird behaviors, 'xterms' is a better 
choice of terminal.


Thanks,

Will

Wow! Where is my flux capacitor when I need it...

Out of curiosity, is the vnc use case something that depends in 
anything 
else but Qemu? I guess the spice case might need some support from intel or 
qxl driver to handle the display.

For now, mediated devices are usable for linux guests and in windows 
may 
be for opencl and background rendering, right?

Thanks Alex for the clarification!

José.
