Without this patch, attempts to create a disk snapshot when qemu is too old results in a cryptic message: virsh # snapshot-create 23 --disk-only error: operation failed: Failed to take snapshot: unknown command: 'snapshot_blkdev' Now it reports: virsh # snapshot-create 23 --disk-only error: unsupported configuration: live disk snapshot not supported with this QEMU binary All versions of qemu that support live disk snapshot also support QMP (basically upstream qemu 1.1 and later, and backports to RHEL 6.2). * src/qemu/qemu_capabilities.h (QEMU_CAPS_DISK_SNAPSHOT): New capability. * src/qemu/qemu_capabilities.c (qemuCaps): Track it. (qemuCapsProbeQMPCommands): Set it. * src/qemu/qemu_driver.c (qemuDomainSnapshotCreateDiskActive): Use it. * src/qemu/qemu_monitor.c (qemuMonitorDiskSnapshot): Simplify. * src/qemu/qemu_monitor_json.c (qemuMonitorJSONDiskSnapshot): Likewise. * src/qemu/qemu_monitor_text.h (qemuMonitorTextDiskSnapshot): Delete. * src/qemu/qemu_monitor_text.c (qemuMonitorTextDiskSnapshot): Likewise.
