Description Andreas Büsching univentionstaff 2010-07-26 14:17:02 CEST
Wenn man versucht ein bereits verwendetes Festplatten-Image einzubinden gibt es eine Warnung, dass dies zu Problemen führen kann. Grundsätzlich erlaubt xen dies. Allerdings nicht, wenn das Image in der selben Maschine mehrfach verwendet wird. Dies führt dann zu einem Fehler.

Beim Hinzufügen von Laufwerken zu existierenden Instanzen wird das erkannt. Allerdings noch nicht beim Anlegen von neuen virtuellen Instanzen

This is no longer the case with UCS-3.x.

> Allerdings noch nicht beim Anlegen von neuen virtuellen Instanzen

This is still true.
So currently duplicate image detection is completely missing.

svn42777: fix a buglet which didn't prevent two new volumes sharing using the exact name. (found while working on Bug #19281).
The other issues remain unfixed.
