[pve-devel] copy_vm: new option -target

[Alexandre DERUMIER]

mmm, good point.

We create the volume with format=2,
then after qemu-img convert copy from source to target.

but maybe qemu-img convert override the format ? seem strange ...

Maybe ceph devel list can help ?

I'll re-read the qemu-img doc.

Hi Alexandre, 

have you checked which rbd format qemu-img creates? I mean we have rbd 
format 1 and format 2. 

In my tests qemu-img always create the slower and older format v1. But 
normally if we clone a VM we should have the same settings of source and 
target disk. 

Greets, 
Stefan
