image - +now its running again. +Additional information: +as i saw - there was a very old qemu-snapshot, which was not properly deleted. +After removing this snapshot, i did reszie the image. +I do suppose, this could be one reason the image (qcow2) got full ? + +Because all is THIN i was not aware of it (fs level ok, storage layer ok). +Is there any tool, how free space in a thin qcow2 file can be monitored ? + + + +``` +PATH=/usr/local/sbin:/usr/local/bin:/usr/sbin:/usr/bin \ +HOME=/var/lib/libvirt/qemu/domain-13-one-89 \ +XDG_DATA_HOME=/var/lib/libvirt/qemu/domain-13-one-89/.local/share \
