[libvirt] A libvirt issue about S3 , please help have a look, thanks

[Zhenfeng Wang]

Hi
I met a issue that while shutdown/reboot a guest which was in pmsuspended status with the acpi mode,
the virsh command appears executed successfully, actually, the guest keep in pmsuspended status and
it didn't shutoff the guest.Then I did the upper operation on my physical host, find the host will
be waked up from the pmsuspended stuatus while i type the shutdown button , so maybe that's the expect
result that the guest can't be shutdown successfully in pmsuspended status. So I think it should report
a proper error or wake up the guest while we shutdown a guest which was in pmsuspended status. Since i'm
not sure about this issue, so i hope you give me some advise to decide that whether we have necessary to
track this issue, thanks.

kernel-3.6.10-4.fc18.x86_64
libvirt-1.1.4-2.fc21.x86_64
qemu-1.4.0-5.fc20.x86_64

steps
1.Prepare a running guest
# virsh list --all
 Id    Name                           State
----------------------------------------------------
 6     rhel7                          running

# vrish dumpxml rhel7
--
  <pm>
    <suspend-to-mem enabled='yes'/>
    <suspend-to-disk enabled='yes'/>
  </pm>

--
    <channel type='unix'>
      <source mode='bind' path='/var/lib/libvirt/qemu/rhel7.agent'/>
      <target type='virtio' name='org.qemu.guest_agent.0'/>
      <alias name='channel1'/>
      <address type='virtio-serial' controller='0' bus='0' port='1'/>
    </channel>

2.Install the qemu-guest-agent packet in the guest, then start the qemu-guest-agent service
#systemctl start qemu-guest-agent

3.Do the S3 with the guest
# virsh dompmsuspend rhel7 --target mem
Domain rhel7 successfully suspended
# virsh list
 Id    Name                           State
----------------------------------------------------
 30    rhel7                          pmsuspended



4.Shutdown the guest with acpi, The command also appears executed successfully, actually, it didn't shutoff the guest
I think it shoud report error here if the guest can't be shutdown successfully.

# virsh shutdown rhel7 --mode acpi
Domain rhel7 is being shutdown

# echo $?
0
# virsh list
 Id    Name                           State
----------------------------------------------------
 30    rhel7                          pmsuspended
