I'm use via php binding
https://libvirt.org/html/libvirt-libvirt-storage.html#virStorageVolCreateXMLFrom
and see that image grows:
image: new.qcow2
file format: qcow2
virtual size: 4.9G (5242880000 bytes)
disk size: 854M
cluster_size: 65536
Format specific information:
compat: 0.10
refcount bits: 16
image: old.qcow2
file format: qcow2
virtual size: 4.9G (5242880000 bytes)
disk size: 277M
cluster_size: 65536
Format specific information:
compat: 1.1
lazy refcounts: false
refcount bits: 16
corrupt: false
Why libvirt create new image with different compat?
