#1075 closed enhancement (wontfix)

Invalid snapshot because of parent modification not detected

Reported by: ugemkow Owned by:
Component: VM control Version: VirtualBox 1.5.4

Description

We are using a configuration, which is not really "standard" on Linux host with Windows XP guest:

We are using a shared VDI which is used readonly used by several client, which create their own snapshot derived from this VDI, so each user has his own "virtual installation" based on this common base vdi.

When modifying this common vdi (installation of a changed base install), VBox does not detect that the snapshots derived from the old install are invalid.

The could be prevented by a simple timestamp in the vdi and its snapshots.

I know, this problem will not occur when using VBox "as designed" so please close this ticket when appropiate

Due to a total rewrite of Snapshot feature in VBox 3.1, this bug seems no longer relevant. Please close it.

ugemkow: If you want to reopen it, please take a look at v3.1 first.

Works as designed. If you change the parent image behind our back, then all snapshots become invalid. The only options you have is to delete all snapshots or to pass the modification to all snapshots.
