Title:
  kvm hangs occasionally when switching out of the qemu console

Status in QEMU:
  New
Status in “qemu” package in Ubuntu:
  Confirmed

Bug description:
  To recreate (although this does *NOT* fail most of the time alas):

  1) press "ctrl-alt-2" to switch to the qemu console.
  2) type say "sendkey ctrl-alt-f1"
  3) press "ctrl-alt-1".

  Expected outcome: Switch to tty1 in the VM.

  Actual outcome: No switch to tty1 in the VM. and qemu console
  unresponsive to any keyboard input.

  
  Rather a vague problem description I'm afraid but this has happened to me 3 times recently. No crash and no excessive CPU is observed.

  I'll grab an strace when it happens again and attach...

Thanks,  James.  I'll aim to test on some older releases and bisect if
possible.

If you have a chance to test on precise, raring, and saucy, or to
actually bisect in the upstream git tree, please let me know.

Hi James,

just a quick check - do you get this with the qemu package in ppa
:ubuntu-virt/candidate?

That is an odd looking list - why is qemu-system-x86 still on 1.7.0,
while qemu-system-common is on 2.0?

Can you still reproduce this issue with the latest version of QEMU, or
could we close this ticket nowadays?

Still happened in qemu 2.5.0 on Ubuntu 16.04, it's random but you can
only switch between console, monitor, serial, parallel several times,
then it hangs.

It seems the issue is sdl related to change in sdl window size. If I
started qemu and set the monitor (and serial & parallel) to the same VC
size, it works much better. Instead of hangs on a 2-3 switches, it may
hang after rapid switch of more than 10 times. Btw, it can hang in any
windows, i.e. display, monitor or serial/parallel.

So the workaround to ease this is, something like '-monitor vc:640x480
-serial vc:640x480'.

Title:
  kvm hangs occasionally when switching out of the qemu console

Status in QEMU:
  Incomplete
Status in qemu package in Ubuntu:
  Confirmed

Bug description:
  To recreate (although this does *NOT* fail most of the time alas):

  1) press "ctrl-alt-2" to switch to the qemu console.
  2) type say "sendkey ctrl-alt-f1"
  3) press "ctrl-alt-1".

  Expected outcome: Switch to tty1 in the VM.

  Actual outcome: No switch to tty1 in the VM. and qemu console
  unresponsive to any keyboard input.

  
  Rather a vague problem description I'm afraid but this has happened to me 3 times recently. No crash and no excessive CPU is observed.

  I'll grab an strace when it happens again and attach...

Could you please check with the latest version of QEMU (v2.12), and make
sure that you're using SDL2 instead of SDL1.2 (since the latter is going
to be removed soon)?
