Description Tomáš Golembiovský 2021-02-16 18:36:41 UTC

It is possible to create clone or a template from snapshot with memory. This is wrong and should not be possible. During the process memory is lost. But when doing memory snapshot the filesystems in guest are not frozen and disk content can be in inconsistent state.

Creating clones or template from memory snapshot should be prohibited.

1. The inconsistency of the file system can also occur when taking a live-snapshot without memory when there's no guest agent installed.
2. This is similar to restore a snapshot that includes memory without restoring its memory in a sense.

Instead of blocking create-vm/template-from-snapshot in that case, we can present a warning as we do in the above mentioned cases to reflect the risk and let the user decide whether to proceed or not.

This bug has low overall severity and passed an automated regression suite, and is not going to be further verified by QE. If you believe special care is required, feel free to re-open to ON_QA status.
