Re: [libvirt] [PATCH 10/13] qemu: Update state of block job to READY only if it actually is ready

Few parts of the code looked at the current progress of and assumed that a two phase blockjob is in the _READY state as soon as the progress reached 100% (info.cur == info.end). In current versions of qemu this assumption is invalid and qemu exposes a new flag 'ready' in the query-block-jobs output that is set to true if the job is actually finished. This patch adds internal data handling for reading the 'ready' flag and acting appropriately as long as the flag is present. While this still doesn't fix the virsh client problem with two phase block jobs and the --pivot option, it at least improves the error message: $ virsh blockcommit --wait --verbose vm vda --base vda[1] --active --pivot Block commit: [100 %]error: failed to pivot job for disk vda error: internal error: unable to execute QEMU command 'block-job-complete': The active block job for device 'drive-virtio-disk0' cannot be completed to $ virsh blockcommit --wait --verbose VM vda --base vda[1] --active --pivot Block commit: [100 %]error: failed to pivot job for disk vda error: block copy still active: disk 'vda' not ready for pivot yet
