The QEMU project is currently considering to move its bug tracking to another
system. For this we need to know which bugs are still valid and which could be
closed already. Thus we are setting older bugs to "Incomplete" now.
If you still think this bug report here is valid, then please switch the state
back to "New" within the next 60 days, otherwise this report will be marked as
"Expired". Or mark it as "Fix Released" if the problem has been solved with a
newer version of QEMU already. Thank you and sorry for the inconvenience.

Title:
Instance of QEMU doesn't unplug virtio scsi disk after device_del and
drive_del commands
Status in QEMU:
Incomplete
Bug description:
device_del and drive_del commands don't cause virtio disk detaching
Steps to reproduce:
1. Run instance
2. Attach virtio scsi disk
3. Reboot instance
4. Immediately after reboot detach disk with QEMU commands:
device_del
drive_del
Expected result:
Disk should be detached anyway
Actual:
Domain info contains attached disk even after waiting long period of time(5
min in my case).
