Hello libvirt users: On QNAP, this is my outcome from the following step "2. Enumerate the current block device(s) in use, again. Notice that the current disk image in use is the above-created overlay, overlay1.qcow2:" I'm showing both pre- and post-execution from the shell. There's 2 files. Should both files be purged according to the instruction "Now you can safely discard the overlay image"? + virsh domblklist 9c7d2c4d-9c28-44bd-8da9-642a63b25c39 Target Source ------------------------------------------------------------------------------- vda /share/Virtual-Machines/SHACKLETON1210/SHACKLETON1210_00.1755932401 hda /share/Virtual-Machines/debian-12.10.0-amd64-netinst.iso ls -alF /share/CACHEDEV2_DATA/Virtual-Machines/SHACKLETON1210/SHACKLETON1210_00.1755932401* -rw-r--r-- 1 admin administrators 177602560 2025-08-23 05:02 SHACKLETON1210_00.1755932401 -rw------- 1 admin administrators 40470118400 2025-08-23 03:42 SHACKLETON1210_00.1755932401.1755934525
