Comment 12 for bug 1930398

Description of problem:
state of cdrom tray is not updated (changed to 'closed') when resetting a VM, but the internal tray state in qemu is actually changed to 'closed' without emission of the tray-changed event.

Version-Release number of selected component (if applicable):
6.2.0/upstream

How reproducible:
always

Steps to Reproduce:
1. boot VM with cdrom
2. issue 'eject' in the guest OS on the cdrom
3. virsh reset VM
4. check tray state in qemu and in libvirt:

Actual results:

$ virsh dumpxml upstream | grep tray
      <target dev='sda' bus='scsi' tray='open'/>
$ virsh qemu-monitor-command --hmp upstream info block
libvirt-3-format: /var/lib/libvirt/images/systemrescuecd-amd64-6.1.2.iso (raw, read-only)
    Attached to: ide0-0-0
    Removable device: locked, tray closed
    Cache mode: writeback

libvirt-2-format: /tmp/blocktest/cd.iso (raw, read-only)
    Attached to: scsi0-0-0
    Removable device: not locked, tray open
    Cache mode: writeback

$ virsh reset upstream
Domain upstream-bj was reset

$ virsh dumpxml upstream | grep tray
      <target dev='sda' bus='scsi' tray='open'/>
$ virsh qemu-monitor-command --hmp upstream info block
libvirt-3-format: /var/lib/libvirt/images/systemrescuecd-amd64-6.1.2.iso (raw, read-only)
    Attached to: ide0-0-0
    Removable device: not locked, tray closed
    Cache mode: writeback

libvirt-2-format: /tmp/blocktest/cd.iso (raw, read-only)
    Attached to: scsi0-0-0
    Removable device: not locked, tray closed
    Cache mode: writeback

Expected results:
Tray state in the XML matches the tray state in qemu.

Additional info:
Same situation happens on 'reboot' initiated from the guest OS.
