Re: [libvirt] [PATCH 1/2] qemu: Get the media status of removable block device

Intorduce new monitor functions to get the media status (ejected or inserted) of removable block device via qemu monitor command "info block". QEMU upstream will expose the the media status like: cd: type=cdrom removable=1 locked=0 ejected=0 The related patch: http://lists.gnu.org/archive/html/qemu-devel/2011-08/msg00408.html

Although it's unlikely to expose other information of removable block device in future via the new function, returned the info in argument "*ejected" just in case of there is new requirement to expose other info. --- src/qemu/qemu_monitor.c | 20 ++++++++ src/qemu/qemu_monitor.h | 3 + src/qemu/qemu_monitor_json.c | 14 ++++++ src/qemu/qemu_monitor_json.h | 4 +- src/qemu/qemu_monitor_text.c | 105 ++++++++++++++++++++++++++++++++++++++++++ src/qemu/qemu_monitor_text.h | 3 + 6 files changed, 148 insertions(+), 1 deletions(-) diff --git a/src/qemu/qemu_monitor.c b/src/qemu/qemu_monitor.c index db6107c..7a41e8f 100644 --- a/src/qemu/qemu_monitor.c +++ b/src/qemu/qemu_monitor.c @@ -1227,6 +1227,26 @@ int qemuMonitorGetBlockStatsInfo(qemuMonitorPtr mon, return ret; } +int qemuMonitorGetRemovableBlockMediaStatus(qemuMonitorPtr mon, + const char *devname, + unsigned int *ejected)
