I'm use via php binding https://libvirt.org/html/libvirt-libvirt-storage.html#virStorageVolCreateXML...
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?
Also, specify compat in xml desc of new disk helps with comat version, but image size grows: image: new2.qcow2 file format: qcow2 virtual size: 4.9G (5242880000 bytes) disk size: 854M cluster_size: 65536 Format specific information: compat: 1.1 lazy refcounts: false refcount bits: 16 corrupt: false -- Vasiliy Tolstov, e-mail: v.tolstov@selfip.ru
