  Which pve snapshot patches you referring? In group case a check should
be done for all snapshot first, and I need to support qmp transaction
interface which is already there, so I build an internal transaction
layer below to make the interface unified and relative easier to add in
qmp transaction.

  what command? can you tip more about the case?
