Description Xianghua Chen 2021-08-11 01:23:46 UTC
Description of problem:
[Machines] Can not delete the vm with a external disk snapshot

Version-Release number of selected components (if applicable):
cockpit-machines-249-1.el9.noarch
cockpit-250-1.el9.x86_64
libvirt-dbus-1.4.1-4.el9.x86_64

How reproducible:
100%

Steps to Reproduce:
1. Prepare a vm
2. Create a snapshot by command, then refresh the vm details page
# virsh snapshot-create-as --domain ${vm_name} --name ${snapshot_name} --description '{Description}' --disk-only
3. Delete the snapshot created in step 3 by clicking 'Delete' button
4. Delete the vm without deleting the image storage file


Actual results:
In step 3, There will be a error shown, which is "unsupported configuration: deletion of 1 external disk snapshots not supported yet"
And the Source file changed to a new image file

In step4, There is also an same error:
VM cirros failed to get deleted
unsupported configuration: deletion of 1 external disk snapshots not supported yet


Expected results:
For the error in step3, will it support deleting external disk snapshot in the future? 
Will we support deleting the vm with external disk in step 4?

Please feel free to close this bug if all are expected and no plan on fixing it, as this scenario rarely happen for customer as we used command to create the snapshot but not with UI. Just want to be clarified here.

Additional info:

Comment 1 Xianghua Chen 2022-12-18 06:48:41 UTC
Latest update:
Package:
cockpit-machines-278-1.el9.noarch
cockpit-280.1-1.el9.x86_64
libvirt-8.10.0-2.el9.x86_64
libvirt-dbus-1.4.1-5.el9.x86_64

There will be no error message show in step 4 now, which should better have a clear message to the customer.

Comment 5 Xianghua Chen 2023-02-16 05:46:53 UTC
I retried this bug with packages:
cockpit-machines-283-1.el9.noarch
cockpit-285-1.el9.x86_64
libvirt-dbus-1.4.1-5.el9.x86_64
libvirt-daemon-9.0.0-3.el9.x86_64

Steps to Reproduce:
1. Prepare a running vm
2. Create a snapshot by command, then refresh the vm details page
# virsh snapshot-create-as --domain ${vm_name} --name ${snapshot_name} --description '{Description}' --disk-only
3. Delete the snapshot created in step 3 by clicking 'Delete' button
The snapshot can be deleted now.
4. Re create the snapshot, then delete the vm without deleting the image storage file
The vm can be deleted now.

So the bug is fixed now.

Hi Katerina, could you set related flags and move it to ON_QA so that I can change it to verified?
