The commands that were introduced in RHEL are a little different from the ones upstream, but we are not going to forward-port the RHEL6 changes. There are improvements in the upstream versions and those are the versions that libvirt uses, too. The new commands in RHEL7 are: - snapshot_blkdev, drive_mirror, block_commit for HMP - blockdev-snapshot-sync, drive-mirror, block-commit for QMP - block_job_complete (HMP) and block-job-complete (QMP) replace __com.redhat_drive-reopen |
Description of problem: KVM QE compared the list of cmd line and devices difference between rhel6.4 and rhel7.0. Found lot of storage migration related commands are different. From KVM QE POV, RHEL7 storage migration related commands should much closer RHEL not upstream. Version-Release number of selected component (if applicable): Host Kernel #uname -r 3.7.0-0.30.el7.x86_64 qemu-kvm version qemu-kvm-1.3.0-3.el7.x86_64 How reproducible: Steps to Reproduce: 1. 2. 3. Actual results: Storage vmotion related commands RHEL6.4 block-stream(copy data from a backing file into a block device) block-job-cancel(stop an active block streaming operation) block-job-set-speed blockdev-snapshot-sync __com.redhat_drive-mirror __com.redhat_drive-reopen __com.redhat_block-commit RHEL7.0 block_stream(copy data from a backing file into a block device) block_job_cancel(stop an active block streaming operation) block_job_set_speed no blockdev-snapshot-sync command on rhel7.0 no __com.redhat_drive-mirror on rhel7.0 no __com.redhat_drive-reopen on rhel7.0 no __com.redhat_block-commit on rhel7.0 Added three commands on rhel7.0, do we support? How to use? block_job_pause block_job_resume block_job_complete Expected results: RHEL7 storage migration related commands should much closer RHEL not upstream Additional info:
