[libvirt] [PATCH 0/9] Add supports for three new QMP events
by Osier Yang 14 Mar '12

14 Mar '12

This patch series adds support for 3 new QMP events: WAKEUP, SUSPEND, and DEVICE_TRAY_MOVED, and related changes on domain's conf and status. [1/9] Add support for tray moved event [2/9] ~ [5/9]: New attribute "tray" is added to disk target, it indicates the tray status of removable disk, i.e. CDROM and Floppy disks, its value could be either of "open" or "closed", defaults to "closed", and a removable disk with tray == "open" won't have the source when domain is started. The value of "tray" will be updated while tray moved event is emitted from guest. Prior to these patches, if the user ejected the medium of removable disk from guest side, and then do migration or save/restoring, the guest will still starts the medium source ,and thus the medium will still exists in guest, which is strange. These patches fix it. [6/9] + [8/9]: Add support for wakeup event, and update the domain status to paused if the domain is running, while the wakeup event is emitted. [7/9] + [9/9]: Add support for suspend event, and update the domain status to running if the domain was paused by suspend event, while the suspend event is emitted. Osier Yang(9) Add support for event tray moved of removable disks docs: Add documentation for new attribute tray of disk target conf: Parse and for the tray attribute qemu: Do not start with source for removable disks if tray is open qemu: Update tray status while tray moved event is emitted Add support for the wakeup event Add support for the event suspend qemu: Update domain status to paused while suspend event is emitted qemu: Update domain status to running while wakeup event is emitted daemon/remote.c | 80 +++++++++++ docs/formatdomain.html.in | 13 ++- docs/schemas/domaincommon.rng | 8 + examples/domain-events/events-c/event-test.c | 61 ++++++++- examples/domain-events/events-python/event-test.py | 12 ++ include/libvirt/libvirt.h.in | 56 ++++++++ python/libvirt-override-virConnect.py | 27 ++++ python/libvirt-override.c | 146 ++++++++++++++++++++ src/conf/domain_conf.c | 33 +++++- src/conf/domain_conf.h | 9 ++ src/conf/domain_event.c | 117 ++++++++++++++++ src/conf/domain_event.h | 10 ++ src/libvirt_private.syms | 6 + src/qemu/qemu_command.c | 16 ++- src/qemu/qemu_monitor.c | 37 +++++ src/qemu/qemu_monitor.h | 14 ++ src/qemu/qemu_monitor_json.c | 37 +++++- src/qemu/qemu_process.c | 131 ++++++++++++++++++ src/remote/remote_driver.c | 98 +++++++++++++ src/remote/remote_protocol.x | 19 +++- src/remote_protocol-structs | 11 ++ tests/qemuxml2argvdata/qemuxml2argv-boot-cdrom.xml | 2 +- .../qemuxml2argv-boot-complex-bootindex.xml | 6 +- .../qemuxml2argvdata/qemuxml2argv-boot-complex.xml | 6 +- .../qemuxml2argvdata/qemuxml2argv-boot-floppy.xml | 2 +- ...uxml2argv-boot-menu-disable-drive-bootindex.xml | 2 +- .../qemuxml2argv-boot-menu-disable-drive.xml | 2 +- .../qemuxml2argv-boot-menu-disable.xml | 2 +- .../qemuxml2argv-boot-menu-enable.xml | 2 +- tests/qemuxml2argvdata/qemuxml2argv-boot-multi.xml | 2 +- tests/qemuxml2argvdata/qemuxml2argv-boot-order.xml | 4 +- tests/qemuxml2argvdata/qemuxml2argv-bootloader.xml | 2 +- tests/qemuxml2argvdata/qemuxml2argv-disk-aio.xml | 2 +- .../qemuxml2argv-disk-cdrom-empty.xml | 2 +- ...qemuxml2argv-disk-cdrom-tray-no-device-cap.args | 4 + .../qemuxml2argv-disk-cdrom-tray-no-device-cap.xml | 32 +++++ .../qemuxml2argv-disk-cdrom-tray.args | 10 ++ .../qemuxml2argv-disk-cdrom-tray.xml | 43 ++++++ tests/qemuxml2argvdata/qemuxml2argv-disk-cdrom.xml | 2 +- .../qemuxml2argv-disk-copy_on_read.xml | 2 +- .../qemuxml2argv-disk-drive-boot-cdrom.xml | 2 +- .../qemuxml2argv-disk-drive-boot-disk.xml | 2 +- .../qemuxml2argv-disk-drive-cache-directsync.xml | 2 +- .../qemuxml2argv-disk-drive-cache-unsafe.xml | 2 +- .../qemuxml2argv-disk-drive-cache-v1-none.xml | 2 +- .../qemuxml2argv-disk-drive-cache-v1-wb.xml | 2 +- .../qemuxml2argv-disk-drive-cache-v1-wt.xml | 2 +- .../qemuxml2argv-disk-drive-cache-v2-none.xml | 2 +- .../qemuxml2argv-disk-drive-cache-v2-wb.xml | 2 +- .../qemuxml2argv-disk-drive-cache-v2-wt.xml | 2 +- ...muxml2argv-disk-drive-error-policy-enospace.xml | 2 +- .../qemuxml2argv-disk-drive-error-policy-stop.xml | 2 +- ...rgv-disk-drive-error-policy-wreport-rignore.xml | 2 +- .../qemuxml2argv-disk-drive-fmt-qcow.xml | 2 +- .../qemuxml2argv-disk-drive-no-boot.xml | 4 +- .../qemuxml2argv-disk-drive-readonly-disk.xml | 2 +- .../qemuxml2argv-disk-drive-readonly-no-device.xml | 2 +- .../qemuxml2argv-disk-drive-shared.xml | 2 +- ...emuxml2argv-disk-floppy-tray-no-device-cap.args | 4 + ...qemuxml2argv-disk-floppy-tray-no-device-cap.xml | 37 +++++ .../qemuxml2argv-disk-floppy-tray.args | 10 ++ .../qemuxml2argv-disk-floppy-tray.xml | 37 +++++ .../qemuxml2argvdata/qemuxml2argv-disk-floppy.xml | 4 +- .../qemuxml2argv-disk-ioeventfd.xml | 2 +- tests/qemuxml2argvdata/qemuxml2argv-disk-order.xml | 2 +- .../qemuxml2argv-disk-snapshot.xml | 2 +- .../qemuxml2argvdata/qemuxml2argv-disk-virtio.xml | 2 +- .../qemuxml2argvdata/qemuxml2argv-disk-xenvbd.xml | 2 +- tests/qemuxml2argvdata/qemuxml2argv-event_idx.xml | 2 +- .../qemuxml2argv-floppy-drive-fat.xml | 2 +- .../qemuxml2argv-graphics-spice-timeout.xml | 2 +- tests/qemuxml2argvdata/qemuxml2argv-lease.xml | 2 +- .../qemuxml2argv-net-bandwidth.xml | 2 +- tests/qemuxml2argvtest.c | 6 + .../qemuxml2xmlout-graphics-spice-timeout.xml | 2 +- tests/vmx2xmldata/vmx2xml-cdrom-ide-device.xml | 2 +- tests/vmx2xmldata/vmx2xml-cdrom-ide-file.xml | 2 +- tests/vmx2xmldata/vmx2xml-cdrom-scsi-device.xml | 2 +- tests/vmx2xmldata/vmx2xml-cdrom-scsi-file.xml | 2 +- tests/vmx2xmldata/vmx2xml-esx-in-the-wild-2.xml | 8 +- tests/vmx2xmldata/vmx2xml-esx-in-the-wild-3.xml | 4 +- tests/vmx2xmldata/vmx2xml-esx-in-the-wild-5.xml | 2 +- tests/vmx2xmldata/vmx2xml-esx-in-the-wild-6.xml | 2 +- tests/vmx2xmldata/vmx2xml-floppy-device.xml | 2 +- tests/vmx2xmldata/vmx2xml-floppy-file.xml | 2 +- tests/vmx2xmldata/vmx2xml-ws-in-the-wild-1.xml | 2 +- tests/vmx2xmldata/vmx2xml-ws-in-the-wild-2.xml | 2 +- tools/virsh.c | 4 + 88 files changed, 1185 insertions(+), 79 deletions(-) Regards, Osier

[libvirt] [PATCH 0/4] Introduce jobs for storage driver
by Michal Privoznik 13 Mar '12

13 Mar '12

Disk operations can take ages to finish. Therefore users might want to abort such job, e.g. because host is going down for maintenance. This patch set is trying to allow this kind of behaviour. The inspiration was taken from qemu driver. How it works: An API that is known to run for a long time, e.g. volume allocation, wiping, have to find a pool which volume belongs to. If the pool was found it is locked. During this time the storage driver is locked. Now the API is preparing for taking the operation. Ideally, it would be sufficient to have only volume locked, but it requires far more changes to code. Just before the API is about to take the long term action, storageBeginJob[WithPool] is called. This wait on a condition specific for a volume. Similar to QEMU driver, wait is limited in time. Timeout is set to 30 seconds. Upon successful job acquire, a counter in the pool is incremented so the pool is prevented from destroy, undef; Then the pool is unlocked. After API finishes it's work, it calls storageEndJob[WithPool] which reset job structure in the volume, re-locks the pool, decrement the counter and broadcasts on the condition. Meanwhile, if the long term action is done internally, it should be done in a cycle so we can check if job abort wasn't signalized. If it is done by external program, we can virCommandAbort() it. Several improvements can be made, but I think this is good for start. NB, I've implemented job aborting for the both APIs using streams, however wasn't very successful with aborting a stream from the daemon site.
