Can not see the Snapshot list for specified Windows VM

[sujunmin]

Hi,
I got problem at I update to latest pve (pve-manager/5.2-2/b1d1c7f4 (running kernel: 4.15.17-3-pve)).

That is when I make snapshot on specified vm, the job will be completed, but there is no snapshot lists on pve web gui, and other vm will list the snapshot list.


the vm info

root@testbox:/data/images/103# qm config 103

and there are configs on the disk and config file

Please help me to solve this problem, thanks.

you have 'parent: Test' in your 'Test' snapshot -> this should not be... (remove it from the 'Test' Snapshot but not from the general part)

can you post your pveversion -v ? and how exactly did you make the snapshot?

 

[sujunmin]

Hi, thanks for your responding.

my pveversion

root@testbox:/home/sujunmin# pveversion
pve-manager/5.2-2/b1d1c7f4 (running kernel: 4.15.17-3-pve)

My instruction to make the snapshot

1. Go to vm's "Snapshots" feature.
2. I can see the "NOW" place on the list
3. Ensure there is no snapshots on vm disk (qemu-info, config file is clean)
3. "Take Snapshot"
4. Type "Test" to "Name" field
5. Popup the progress bar, and complete
6. The Snapshot "Test" and "Now" are all disappeared.
7. use qemu-img info, view the vm config file, there are "Test" Snapshot on them (at my first post).

Updated

When I remove the "parent", and it works now. Maybe this feature need to check if parent exists first?
