I'd agree that at least the last part - removing the oldest snapshot
first - seems like a bug.

Title:
  'qemu-img snapshot' allows new snapshot to be created with the name of
  an existing snapshot

Status in QEMU:
  New
Status in “qemu” package in Ubuntu:
  New

Bug description:
  qemu-img _may_ be working as designed, but it feels like this could be
  a bug. I'd certainly prefer to only allow unique snapshot names
  (unless maybe something like a "--force-non-unique-snapshot-names" was
  also specified).

  If this really is correct behaviour, it should be documented as qemu-
  img(1) currently specifies no details whatsoever regarding expected
  behaviour or valid snapshot names.

  $ qemu-img snapshot -l image.cow 
  $ qemu-img snapshot -c foo image.cow        
  $ qemu-img snapshot -l image.cow

  $ qemu-img snapshot -d foo image.cow

  $ qemu-img snapshot -d foo image.cow 
  $ qemu-img snapshot -l image.cow 
  $

  Note also how snapshot deletion works in reverse order - the oldest
  snapshot with a given name is deleted first.

The QEMU project is currently considering to move its bug tracking to another system. For this we need to know which bugs are still valid and which could be closed already. Thus we are setting older bugs to "Incomplete" now.
If you still think this bug report here is valid, then please switch the state back to "New" within the next 60 days, otherwise this report will be marked as "Expired". Or mark it as "Fix Released" if the problem has been solved with a newer version of QEMU already. Thank you and sorry for the inconvenience.

Title:
  'qemu-img snapshot' allows new snapshot to be created with the name of
  an existing snapshot

Status in QEMU:
  Expired
Status in qemu package in Ubuntu:
  Expired

Bug description:
  qemu-img _may_ be working as designed, but it feels like this could be
  a bug. I'd certainly prefer to only allow unique snapshot names
  (unless maybe something like a "--force-non-unique-snapshot-names" was
  also specified).

  If this really is correct behaviour, it should be documented as qemu-
  img(1) currently specifies no details whatsoever regarding expected
  behaviour or valid snapshot names.

  $ qemu-img snapshot -l image.cow 
  $ qemu-img snapshot -c foo image.cow        
  $ qemu-img snapshot -l image.cow            
  Snapshot list:
  ID        TAG                 VM SIZE                DATE       VM CLOCK
  1         foo                       0 2014-11-26 08:30:53   00:00:00.000
  $ qemu-img snapshot -c foo image.cow 
  $ qemu-img snapshot -l image.cow            
  Snapshot list:
  ID        TAG                 VM SIZE                DATE       VM CLOCK

  2         foo                       0 2014-11-26 08:30:58   00:00:00.000

  $ qemu-img snapshot -d foo image.cow        
  $ qemu-img snapshot -l image.cow            
  Snapshot list:
  ID        TAG                 VM SIZE                DATE       VM CLOCK
  2         foo                       0 2014-11-26 08:30:58   00:00:00.000
  3         foo                       0 2014-11-26 08:31:00   00:00:00.000
  $ qemu-img snapshot -d foo image.cow 
  $ qemu-img snapshot -l image.cow            
  Snapshot list:
  ID        TAG                 VM SIZE                DATE       VM CLOCK
  3         foo                       0 2014-11-26 08:31:00   00:00:00.000
  $ qemu-img snapshot -d foo image.cow 
  $ qemu-img snapshot -l image.cow 
  $

  Note also how snapshot deletion works in reverse order - the oldest
  snapshot with a given name is deleted first.
