Hello, it happened with another VM: # virsh snapshot-create-as --domain rasa sn1 --diskspec vda,file=/var/lib/libvirt/images/rasa-sn1.qcow2 --disk-only --atomic --no-metadata # virsh blockcommit rasa vda --active --verbose --pivot Block commit: [100 %]error: failed to pivot job for disk vda error: block copy still active: disk 'vda' not ready for pivot yet # virsh domblklist rasa Target Source ------------------------------------------------ vda /var/lib/libvirt/images/rasa-sn1.qcow2 If blockcommit had succeeded, it would be now: vda /var/lib/libvirt/images/rasa.qcow2 Now both files rasa.qcow2 and rasa-sn1.qcow2 are written to, and # virsh blockjob rasa vda Active Block Commit: [100 %] But trying to virsh blockcommit rasa vda --active --verbose --pivot once more: error: block copy still active: disk 'vda' already in active block job How do I make rasa.qcow2 the only active vda? I use qemu-kvm-ev-2.3.0-29.1.el7. Thanks, Nerijus
