Creating datablock from sunstone (qcow2)


When our users try to create a datablock using sunstone he gives a file formated as qcow3.

There are any option to set sunstone to create a qcow2? because some of our dom0 using yet old software versions.

qemu-img convert -f qcow2 -O qcow2 file.qcow3 file.qcow2


in one hand I must to say that in some versions of qemu that command not work because by default it use 2.3 version. you need to use option=compat 0.10

in the other hand, im asking to perform a datablock using sunstone because the users just have acces to that resource and can’t perform ssh to frontent… i need to know how modify sunstone or where it execute the command to modify.
