Hello Thomas,

here my answer per email:

I re-tested that simple sequence above and it seems to work now,
using qemu-2.8.0 !

I did not use qemu-ppc again in the past five years, so I can not tell
you "when" this got fixed (which exact version). At least it seems to
work "now" :-)



Unfortunately that stupid bugtracker seems to be broken, here what I get
when I press the button to send the "Post Comment" button:

Title:
  qemu-system-ppc: no keyboard after savevm/loadvm

Status in QEMU:
  Incomplete

Bug description:
  Here the steps to reproduce:

  1. qemu-img create -f qcow2 test.qcow2 100M
  2. qemu-system-ppc -m 1024 -hda test.qcow2
  3. change to the console via Ctrl-Alt-2 and save a snapshot: "savevm test"
  4. quit
  5. start again and go to the console
  6. load the snapshot via "loadvm test"
  7. change back to the guest display (Ctrl-Alt-1)
  8. try to type something => no keyboard
  9. the same via console, e.g. "sendkey 1" has no effect

  I tried the following branches from git:
  master, stable-1.0, stable-0.15 
  => all behave the same
