Hi Guys,
I have hit an issue on testing against our testbed, It's failed to eject cdrom
media after reboot from installed the guest OS.
The reproduce step:
1. Attach a block device with a ISO media and start install VM from ISO.
2. <disk type='block' device='cdrom'>
<driver name='qemu' type='raw'/>
<source
dev='/dev/disk/by-id/pbdx-vol-cfe60dca-c271-491b-be3c-11fa8d7625a4' index='6'/>
<backingStore/>
<target dev='hda' bus='ide' tray='open'/>
<readonly/>
<alias name='ide0-0-0'/>
<address type='drive' controller='0' bus='0' target='0' unit='0'/>
</disk>
3. After installed the OS and reboot from system disk successful.
4. Then I want to eject CDROM through update device with the xml like below
or using virsh tool 'virsh change-media iso_test hda --eject'
5. All those will failed at "internal error: unable to execute QEMU command
'blockdev-remove-medium': Tray of device 'ide0-0-0' is not open"
<disk type='block' device='cdrom'>
<driver name='qemu' type='raw'/>
<backingStore/>
<target dev='hda' bus='ide' tray='open'/>
<readonly/>
<alias name='ide0-0-0'/>
<address type='drive' controller='0' bus='0' target='0' unit='0'/>
</disk>
block info looks like below:
virsh qemu-monitor-command iso_test --hmp info block
setlocale: No such file or directory
libvirt-6-format: /dev/disk/by-id/pbdx-vol-cfe60dca-c271-491b-be3c-11fa8d7625a4
(raw, read-only)
Attached to: ide0-0-0
Removable device: locked, tray closed
Cache mode: writeback
Reproduce envrionment:
Operating system: rhat8.4
Architecture:x86
kernel version:4.18.0-305
libvirt version:v7.9.0(private build)
Hypervisor and version:QEMU 5.1.0(private build)
Is there any workaround? Any comments are appreciated.
Thanks!
