2018-06-29dump: add Windows dump format to dump-guest-memoryViktor Prutyanov
This patch adds Windows crashdumping feature. Now QEMU can produce ELF-dump containing Windows crashdump header, which can help to convert to a valid WinDbg-understandable crashdump file, or immediately create such file. The crashdump will be obtained by joining physical memory dump and 8K header exposed through vmcoreinfo/fw_cfg device by guest driver at BSOD time. Option '-w' was added to dump-guest-memory command. At the moment, only x64 configuration is supported.

2018-06-18block/mirror: Add active mirroringMax Reitz
This patch implements active synchronous mirroring. In active mode, the passive mechanism will still be in place and is used to copy all initially dirty clusters off the source disk; but every write request will write data both to the source and the target disk, so the source cannot be dirtied faster than data is mirrored to the target. Also, once the block job has converged (BLOCK_JOB_READY sent), source and target are guaranteed to stay in sync (unless an error occurs). Active mode is completely optional and currently disabled at runtime. A later patch will add a way for users to enable it.

2018-06-15rbd: New parameter key-secretMarkus Armbruster
Legacy -drive supports "password-secret" parameter that isn't available with -blockdev / blockdev-add. That's because we backed out our first try to provide it there due to interface design doubts, in commit 577d8c9a811, v2.9.0. This is the second try. It brings back the parameter, except it's named "key-secret" now. Let's review our reasons for backing out the first try, as stated in the commit message: * BlockdevOptionsRbd member @password-secret isn't actually a password, it's a key generated by Ceph. Addressed by the rename. * We're not sure where member @password-secret belongs (see the previous commit). See previous commit. * How @password-secret interacts with settings from a configuration file specified with @conf is undocumented. Not actually true, the documentation for @conf says "Values in the configuration file will be overridden by options specified via QAPI", and we've tested this.

2018-06-15rbd: New parameter auth-client-requiredMarkus Armbruster
Parameter auth-client-required lets you configure authentication methods. We tried to provide that in v2.9.0, but backed out due to interface design doubts (commit 464444fcc16). This commit is similar to what we backed out, but simpler: we use a list of enumeration values instead of a list of objects with a member of enumeration type. Let's review our reasons for backing out the first try, as stated in the commit message: * The implementation uses deprecated rados_conf_set() key "auth_supported". No biggie. Fixed: we use "auth-client-required". * The implementation makes -drive silently ignore invalid parameters "auth" and "auth-supported.*.X" where X isn't "auth". Fixable (in fact I'm going to fix similar bugs around parameter server), so again no biggie. That fix is commit 2836284db60. This commit doesn't bring the bugs back. * BlockdevOptionsRbd member @password-secret applies only to authentication method cephx. Should it be a variant member of RbdAuthMethod? We've had time to ponder, and we decided to stick to the way Ceph configuration works: the key configured separately, and silently ignored if the authentication method doesn't use it. * BlockdevOptionsRbd member @user could apply to both methods cephx and none, but I'm not sure it's actually used with none. If it isn't, should it be a variant member of RbdAuthMethod? Likewise. * The client offers a *set* of authentication methods, not a list. Should the methods be optional members of BlockdevOptionsRbd instead of members of list @auth-supported? The latter begs the question what multiple entries for the same method mean. Trivial question now that RbdAuthMethod contains nothing but @type, but less so when RbdAuthMethod acquires other members, such the ones discussed above. Again, we decided to stick to the way Ceph configuration works, except we make auth-client-required a list of enumeration values instead of a string containing keywords separated by delimiters. * How BlockdevOptionsRbd member @auth-supported interacts with settings from a configuration file specified with @conf is undocumented. I suspect it's untested, too. Not actually true, the documentation for @conf says "Values in the configuration file will be overridden by options specified via QAPI", and we've tested this.

2018-06-04migration: Don't activate block devices if using -SDr. David Alan Gilbert
Activating the block devices causes the locks to be taken on the backing file. If we're running with -S and the destination libvirt hasn't started the destination with 'cont', it's expecting the locks are still untaken. Don't activate the block devices if we're not going to autostart the VM; 'cont' already will do that anyway. This change is tied to the new migration capability 'late-block-activate' that defaults to off, keeping the old behaviour by default. bz: https://bugzilla.redhat.com/show_bug.cgi?id=1560854 Signed-off-by: Dr. David Alan Gilbert <dgilbert@redhat.com> Reviewed-by: Juan Quintela <quintela@redhat.com> Signed-off-by: Juan Quintela <quintela@redhat.com>

For example, PIIX4 does that from piix4_pm_realize() via piix4_pm_add_propeties(): object_property_add_uint8_ptr(OBJECT(s), ACPI_PM_PROP_ACPI_ENABLE_CMD, &acpi_enable_cmd, NULL); This adds a note to the command descriptions about the limitation.

Command is allowed to run only in preconfig stage and will allow to configure numa mapping for CPUs depending on possible CPUs layout (query-hotpluggable-cpus) for given machine instance. Example of configuration session: $QEMU -smp 2 --preconfig ... QMP: -> {'execute': 'query-hotpluggable-cpus' } <- {'return': [ {'props': {'core-id': 0, 'thread-id': 0, 'socket-id': 1}, ... }, {'props': {'core-id': 0, 'thread-id': 0, 'socket-id': 0}, ... } ]} -> {'execute': 'set-numa-node', 'arguments': { 'type': 'node', 'nodeid': 0 } } <- {'return': {}} -> {'execute': 'set-numa-node', 'arguments': { 'type': 'cpu', 'node-id': 0, 'core-id': 0, 'thread-id': 0, 'socket-id': 1, } } <- {'return': {}} -> {'execute': 'set-numa-node', 'arguments': { 'type': 'node', 'nodeid': 1 } } -> {'execute': 'set-numa-node', 'arguments': { 'type': 'cpu', 'node-id': 1, 'core-id': 0, 'thread-id': 0, 'socket-id': 0 } } <- {'return': {}} -> {'execute': 'query-hotpluggable-cpus' } <- {'return': [ {'props': {'core-id': 0, 'thread-id': 0, 'node-id': 0, 'socket-id': 1}, ... }, {'props': {'core-id': 0, 'thread-id': 0, 'node-id': 1, 'socket-id': 0}, ... } ]} Signed-off-by: Igor Mammedov <imammedo@redhat.com> Message-Id: <1525423069-61903-11-git-send-email-imammedo@redhat.com> Reviewed-by: Eduardo Habkost <ehabkost@redhat.com> [ehabkost: Changed "since 2.13" to "since 3.0"] Signed-off-by: Eduardo Habkost <ehabkost@redhat.com>
2018-05-30qmp: permit query-hotpluggable-cpus in preconfig stateIgor Mammedov
it will allow mgmt to query possible CPUs, which depends on used machine(version)/-smp options, without restarting QEMU and use results to configure numa mapping or adding CPUs with device_add* later. PS: *) device_add is not allowed to run at preconfig in this series but later it could be dealt with by injecting -device in preconfig state and letting existing -device handling to actually plug devices Signed-off-by: Igor Mammedov <imammedo@redhat.com> Message-Id: <1525423069-61903-10-git-send-email-imammedo@redhat.com> Reviewed-by: Eduardo Habkost <ehabkost@redhat.com> Signed-off-by: Eduardo Habkost <ehabkost@redhat.com>
2018-05-30cli: add --preconfig optionIgor Mammedov
This option allows pausing QEMU in the new RUN_STATE_PRECONFIG state, allowing the configuration of QEMU from QMP before the machine jumps into board initialization code of machine_run_board_init() The intent is to allow management to query machine state and additionally configure it using previous query results within one QEMU instance (i.e. eliminate the need to start QEMU twice, 1st to query board specific parameters and 2nd for actual VM start using query results for additional parameters). The new option complements -S option and could be used with or without it. The difference is that -S pauses QEMU when the machine is completely initialized with all devices wired up and ready to execute guest code (QEMU needs only to unpause VCPUs to let guest execute its code), while the "preconfig" option pauses QEMU early before board specific init callback (machine_run_board_init) is executed and allows the configuration of machine parameters which will be used by board init code. When early introspection/configuration is done, command 'exit-preconfig' should be used to exit RUN_STATE_PRECONFIG and transition to the next requested state (i.e. if -S is used then QEMU will pause the second time when board/device initialization is completed or start guest execution if -S isn't provided on CLI) PS: Initially 'preconfig' is planned to be used for configuring numa topology depending on board specified possible cpus layout.

2018-05-30qapi: introduce new cmd option "allow-preconfig"Igor Mammedov
New option will be used to allow commands, which are prepared/need to run, during preconfig state. Other commands that should be able to run in preconfig state, should be amended to not expect machine in initialized state or deal with it. For compatibility reasons, commands that don't use new flag 'allow-preconfig' explicitly are not permitted to run in preconfig state but allowed in all other states like they used to be. Within this patch allow following commands in preconfig state: qmp_capabilities query-qmp-schema query-commands query-command-line-options query-status exit-preconfig to allow qmp connection, basic introspection and moving to the next state. PS: set-numa-node and query-hotpluggable-cpus will be enabled later in a separate patches.

2018-05-30block/create: Make x-blockdev-create a jobKevin Wolf
This changes the x-blockdev-create QMP command so that it doesn't block the monitor and the main loop any more, but starts a background job that performs the image creation. The basic job as implemented here is all that is necessary to make image creation asynchronous and to provide a QMP interface that can be marked stable, but it still lacks a few features that jobs usually provide: The job will ignore pause commands and it doesn't publish more than very basic progress yet (total-progress is 1 and current-progress advances from 0 to 1 when the driver callbacks returns). These features can be added later without breaking compatibility. Signed-off-by: Kevin Wolf <kwolf@redhat.com> Reviewed-by: Max Reitz <mreitz@redhat.com> Reviewed-by: Jeff Cody <jcody@redhat.com>
