You can also check the Nova compute.log for more contextual details of why the operation failed. > Exception during message handling: block copy still active: domain has > active block job > > In libvirt log file I can see: > error : qemuDomainDefineXML:6312 : block copy still active: domain has > active block job > > Libvirt is 1.2.7 version, linux system is Debian Wheezy > > Please, what does it mean ? It means, according to libvirt, there's an unfinished `blockcopy` (Copy a disk backing image chain to destination ) operation. If you can find the associated libvirt guest name, you can try the below maybe. For the Nova libvirt guest that you're trying to create a snapshot of, find the location of its current block device: $ virsh domblklist instance-YYYYYYYYY Then check if there are active block operaations for that disk: $ virsh blockjob instance-YYYYYYYYY /path/to/libvirt/disk/ --info If there is any operation and if it is a test environment, you can run the below to abort the block operation in progress: $ virsh blockjob instance-YYYYYYYYY /path/to/libvirt/disk/ --abort. Please the man page of `virsh` for more details.
