Bug 738241

Marian,

Can you please try to reproduce it using a Linux guest and provide the libvirt version you're running?

This is likely to be the expected behavior though. What's happening here is that, when you run qemu with -no-shutdown, it will stop the VM instead of exiting when the guest shuts down. This means that it's perfectly possible to resume VM execution and/or try to shutdown again. If you do try to shutdown again, you'll see the same sequence of events (SHUTDOWN followed by STOP).

BTW, current libvirt really doesn't care how many SHUTDOWN events are sent by qemu. All but the first one are just ignored.

Thanks for the feedback Jiri.

I won't close it though, I want to confirm it's not a qemu issue. Will move to 6.3, as it's not a blocker (nor exception).

Marian, please note that I still need your feedback.

Luiz,

I can reproduce with Linux -> the same behaviour, with libvirt-0.9.4-19.el6.x86_64, seems that this version of libvirt has explanation log messages of what Jiri mentioned:
The second SHUTDOWN:
09:51:50.243: 14112: debug : qemuProcessShutdownOrReboot:439 : Ignoring repeated SHUTDOWN event from domain rhel

I am not really sure what feedback you need, can you please specify? I do not understand why the second SHUTDOWN event is sent when It is ignored by libvirt anyway or why the order is SHUTDOWN -> STOP and not STOP -> SHUTDOWN.
Anyway I do not understand qemu events that much and if you consider it to be correct then close this report. Thank you for investigation though.

reproduced bug with qemu-kvm-0.12.1.2-2.233.el6.x86_64

reproduce to step:
1.boot a windows2008r2 guest with virt-manager
2.change libvirt log level(enable debug mode)
edit /etc/libvirt/libvirtd.conf
  set and add the following two lines
  log_filters="1:qemu_monitor_json 1:qemu_driver"
  log_outputs="1:file:/var/log/libvirt/libvirtd.log"
  service libvirtd restart
3. shutdown guest inside guest

actual result:

I would just close this issue. Libvirt doesn't care (the second SHUTDOWN event is just ignored) and direct use of qemu-kvm in RHEL is not supported. Thus this bug seems to be just a cleanup thing which can be made upstream but there's no need to push for having it in RHEL.

Yes, comment 11 is right. I let this one opened just to remind me that I had to look at it, but if it doesn't affect RHEL we can close it.
