Created attachment 957997 [details] logs from engine&vdsm while trying the action with xml protocol at the host This bug was initially assigned to Storage team- after looking at the bug it seems to be that the problem is related to the host's JSON protocol. the logs that was initially attached are logs generated while the host's protocol was JSON. this attachment is the logs while the protocol is XML which works with no errors.
Piotr, can you take a look please?
It looks like command_info is missing VM_diskSizeExtend
