Description Avital Pinnick 2017-10-23 06:38:38 UTC

When live or cold merge fails, snapshot disks may be left in an illegal state. If VMs with illegal snapshot disks are shut down, they will not re-start. VMs with illegal snapshot disks are now marked with an exclamation mark and a warning message not to shut them down.

Note should be added to info guide. If VMs with illegal snapshots are shut down, they might not start up again.

Hi Ala
I will be documenting this bug. I read through all the comments in https://bugzilla.redhat.com/show_bug.cgi?id=1372163 and I have some questions regarding the scope of the solution you implemented.

1. In addition to the explanation mark, did you add the dialog box that will pop up if the user tries to showdown with an illegal snapshot?

2. Did you add an indication to the snapshot tab, as per this comment:

> It would also be nice to indicate on each VMs Snapshot Tab which Snapshot
> needs to be retried ... hopefully I'm not asking too much :)

>I will see what can be done.

3. I'm not clear on what we want the user to try to do. Are "snapshot delete and cold merge the same? The tooltip refers to snapshot deletion but the automated solution that German suggested was to automatically continue the cold merge, if the VM is shutdown before fixing the issue.

Snapshot deletion and merge refers to the same thing.
Merge can be live if the VM is up, and cold if the VM is down.

Hope this helps.
