Today I tested the series with a Windows Server 2012 R2 guest as well.

As I had written before, Windows' default display driver for the GOP
doesn't support S3.

I installed the work-in-progress WDDM driver (version 0.2) for the QXL
card. (The binary I used is publicly available, but I'm still waiting
for an OK whether I can reference it.)

It only installs if the revision property of the qxl-vga device is set
to 3 on the qemu command line, as in

  -device qxl-vga,[...],revision=3

With the driver installed, the "psshutdown -d" command from PsTools:

  http://technet.microsoft.com/en-us/sysinternals/bb897541.aspx

suspends the VM.

I can resume the VM with the usual "system_wakeup" qemu monitor command.
The display doesn't come back (probably a problem in the guest driver).
However, the VM does work -- I can continue entering commands at the SAC
prompt over serial ("virsh console").

For example I opened a Command Prompt channel with the "cmd" command,
switched to it with the "ch -sn Cmd0001" command, logged in, and then I
could ping (using the normal ping utility) a public host. I could even
re-invoke the psshutdown utility, suspend-resume-ping again, and then
power off the VM gracefully ("psshutdown -k").

I think this again qualifies as a successful test for the series.

Thanks,
Laszlo
