s that right? Here I'm successfully cloning a volume across two storage pools:
Yes, it works but.... Source image: image: /var/lib/libvirt/images/sda/143177 file format: qcow2 virtual size: 5.0G (5368709120 bytes) disk size: 902M cluster_size: 65536 Format specific information: compat: 0.10 refcount bits: 16
Dest image: image: /var/lib/libvirt/images/sda/test file format: qcow2 virtual size: 5.0G (5368709120 bytes) disk size: 902M cluster_size: 65536 Format specific information: compat: 0.10 refcount bits: 16
But -rw------- 1 root 908M Apr 18 13:59 143177 -rw------- 1 root 902M Apr 18 13:59 test
Why size is changed on destination image? In case of cp --spwarse=always size does not changed.
As Michal and Daniel said, this should not be a problem. Also, you can check the content is the same using virt-diff (part of libguestfs): # virt-diff \ -a /var/lib/libvirt/images/sda/143177 \ -A /var/lib/libvirt/images/sda/test > log Most probably log should be empty, since the actual content of the image did not change. -- Pino Toscano
