We won't support direct usage of qemu-kvm and/or QMP/HMP in RHEL7. Closing as WONTFIX. |
Description of problem: When do block_stream without specify the speed, use query-block-jobs check the speed is 0. But the real speed is not 0, so maybe qmp should give a reasonable speed value as default(without specify the speed).
