2018-01-15migration: add postcopy total blocktime into query-migrateAlexey Perevalov
Postcopy total blocktime is available on destination side only. But query-migrate was possible only for source. This patch adds ability to call query-migrate on destination. To be able to see postcopy blocktime, need to request postcopy-blocktime capability. The query-migrate command will show following sample result: {"return": "postcopy-vcpu-blocktime": [115, 100], "status": "completed", "postcopy-blocktime": 100 }} postcopy_vcpu_blocktime contains list, where the first item is the first vCPU in QEMU. This patch has a drawback, it combines states of incoming and outgoing migration. Ongoing migration state will overwrite incoming state. Looks like better to separate query-migrate for incoming and outgoing migration or add parameter to indicate type of migration.

2017-12-22block: Document that x-blockdev-change breaks quorum children listKevin Wolf
Removing a quorum child node with x-blockdev-change results in a quorum driver state that cannot be recreated with create options because it would require a list with gaps.

2017-12-19blockdev: add x-blockdev-set-iothread force booleanStefan Hajnoczi
When a node is already associated with a BlockBackend the x-blockdev-set-iothread command refuses to set the IOThread. This is to prevent accidentally changing the IOThread when the nodes are in use. When the nodes are created with -drive they automatically get a BlockBackend. In that case we know nothing is using them yet and it's safe to set the IOThread. Add a force boolean to override the check.

2017-12-19blockdev: add x-blockdev-set-iothread testing commandStefan Hajnoczi
Currently there is no easy way for iotests to ensure that a BDS is bound to a particular IOThread. Normally the virtio-blk device calls blk_set_aio_context() when dataplane is enabled during guest driver initialization. This never happens in iotests since -machine accel=qtest means there is no guest activity (including device driver initialization). This patch adds a QMP command to explicitly assign IOThreads in test cases. See qapi/block-core.json for a description of the command.

2017-11-27QAPI & interop: Clarify events emitted by 'block-job-cancel'Kashyap Chamarthy
When you cancel an in-progress 'mirror' job (or "active `block-commit`") with QMP `block-job-cancel`, it emits the event: BLOCK_JOB_CANCELLED. However, when `block-job-cancel` is issued *after* `drive-mirror` has indicated (via the event BLOCK_JOB_READY) that the source and destination have reached synchronization: [...] # Snip `drive-mirror` invocation & outputs { "execute":"block-job-cancel", "arguments":{ "device":"virtio0" } } {"return": {}} It (`block-job-cancel`) will counterintuitively emit the event 'BLOCK_JOB_COMPLETED': { "timestamp":{ "seconds":1510678024, "microseconds":526240 }, "event":"BLOCK_JOB_COMPLETED", "data":{ "device":"virtio0", "len":41126400, "offset":41126400, "speed":0, "type":"mirror" } } But this is expected behaviour, where the _COMPLETED event indicates that synchronization has successfully ended (and the destination now has a point-in-time copy, which is at the time of cancel). So add a small note to this effect in 'block-core.json'. While at it, also update the "Live disk synchronization -- drive-mirror and blockdev-mirror" section in 'live-block-operations.rst'.

2017-11-21migration, xen: Fix block image lock issue on live migrationAnthony PERARD
When doing a live migration of a Xen guest with libxl, the images for block devices are locked by the original QEMU process, and this prevent the QEMU at the destination to take the lock and the migration fail. >From QEMU point of view, once the RAM of a domain is migrated, there is two QMP commands, "stop" then "xen-save-devices-state", at which point a new QEMU is spawned at the destination. Release locks in "xen-save-devices-state" so the destination can takes them, if it's a live migration. This patch add the "live" parameter to "xen-save-devices-state" which default to true so older version of libxenlight can work with newer version of QEMU.

2017-11-17block: Deprecate bdrv_set_read_only() and usersKevin Wolf
bdrv_set_read_only() is used by some block drivers to override the read-only option given by the user. This is not how read-only images generally work in QEMU: Instead of second guessing what the user really meant (which currently includes making an image read-only even if the user didn't only use the default, but explicitly said read-only=off), we should error out if we can't provide what the user requested. This adds deprecation warnings to all callers of bdrv_set_read_only() so that the behaviour can be corrected after the usual deprecation period. Signed-off-by: Kevin Wolf <kwolf@redhat.com>

2017-10-13tpm: Added support for TPM emulatorAmarnath Valluri
This change introduces a new TPM backend driver that can communicate with swtpm(software TPM emulator) using unix domain socket interface. QEMU talks to the TPM emulator using QEMU's socket-based chardev backend device. Swtpm uses two Unix sockets for communications, one for plain TPM commands and responses, and one for out-of-band control messages. QEMU passes the data socket to be used over the control channel.

2017-09-22scsi, file-posix: add support for persistent reservation managementPaolo Bonzini
It is a common requirement for virtual machine to send persistent reservations, but this currently requires either running QEMU with CAP_SYS_RAWIO, or using out-of-tree patches that let an unprivileged QEMU bypass Linux's filter on SG_IO commands. As an alternative mechanism, the next patches will introduce a privileged helper to run persistent reservation commands without expanding QEMU's attack surface unnecessarily. The helper is invoked through a "pr-manager" QOM object, to which file-posix.c passes SG_IO requests for PERSISTENT RESERVE OUT and PERSISTENT RESERVE IN commands. For example: $ qemu-system-x86_64 -device virtio-scsi \ -object pr-manager-helper,id=helper0,path=/var/run/qemu-pr-helper.sock -drive if=none,id=hd,driver=raw,file.filename=/dev/sdb,file.pr-manager=helper0 -device scsi-block,drive=hd or: $ qemu-system-x86_64 -device virtio-scsi \ -object pr-manager-helper,id=helper0,path=/var/run/qemu-pr-helper.sock -blockdev node-name=hd,driver=raw,file.driver=host_device,file.filename=/dev/sdb,file.pr-manager=helper0 -device scsi-block,drive=hd Multiple pr-manager implementations are conceivable and possible, though only one is implemented right now. For example, a pr-manager could: - talk directly to the multipath daemon from a privileged QEMU (i.e. QEMU links to libmpathpersist); this makes reservation work properly with multipath, but still requires CAP_SYS_RAWIO - use the Linux IOC_PR_* ioctls (they require CAP_SYS_ADMIN though) - more interestingly, implement reservations directly in QEMU through file system locks or a shared database (e.g. sqlite) Signed-off-by: Paolo Bonzini <pbonzini@redhat.com>

2017-09-05block: convert ThrottleGroup to object with QOMManos Pitsidianakis
ThrottleGroup is converted to an object. This will allow the future throttle block filter drive easy creation and configuration of throttle groups in QMP and cli. A new QAPI struct, ThrottleLimits, is introduced to provide a shared struct for all throttle configuration needs in QMP. ThrottleGroups can be created via CLI as -object throttle-group,id=foo,x-iops-total=100,x-.. where x-* are individual limit properties. Since we can't add non-scalar properties in -object this interface must be used instead. However, setting these properties must be disabled after initialization because certain combinations of limits are forbidden and thus configuration changes should be done in one transaction. The individual properties will go away when support for non-scalar values in CLI is implemented and thus are marked as experimental. ThrottleGroup also has a `limits` property that uses the ThrottleLimits struct. It can be used to create ThrottleGroups or set the configuration in existing groups as follows: { "execute": "object-add", "arguments": { "qom-type": "throttle-group", "id": "foo", "props" : { "limits": { "iops-total": 100 } } } } { "execute" : "qom-set", "arguments" : { "path" : "foo", "property" : "limits", "value" : { "iops-total" : 99 } } } This also means a group's configuration can be fetched with qom-get.

2017-09-04qapi-schema: Introspection doc is in the wrong section, fixMarkus Armbruster
