| * mirror: add support for on-source-error/on-target-errorPaolo Bonzini2012-10-241-1/+7
| | | | | | | | | | | | | | | | | | | | | | | | | | | | Error management is important for mirroring; otherwise, an error on the target (even something as "innocent" as ENOSPC) requires to start again with a full copy. Similar to on_read_error/on_write_error, two separate knobs are provided for on_source_error (reads) and on_target_error (writes). The default is 'report' for both. The 'ignore' policy will leave the sector dirty, so that it will be retried later. Thus, it will not cause corruption.

| | | | | | | | | | | | | | | | | | | | | | | | | | While streaming can be dropped as soon as it progressed through the whole image, mirroring needs to be completed manually for two reasons: 1) so that management knows exactly when the VM switches to the target; 2) because for other use cases such as replication, we may leave the operation running for the whole life of the virtual machine. Add a new block job command that manually completes background operations. Signed-off-by: Paolo Bonzini <pbonzini@redhat.com> Signed-off-by: Kevin Wolf <kwolf@redhat.com>

| | | | | | | | | | | | | | | | | | | | | | | | | | This patch adds support that enables passing of file descriptors to the QEMU monitor where they will be stored in specified file descriptor sets. A file descriptor set can be used by a client like libvirt to store file descriptors for the same file. This allows the client to open a file with different access modes (O_RDWR, O_WRONLY, O_RDONLY) and add/remove the passed fds to/from an fd set as needed. This will allow QEMU to (in a later patch in this series) "open" and "reopen" the same file by dup()ing the fd in the fd set that corresponds to the file, where the fd has the matching access mode flag that QEMU requests. The new QMP commands are: add-fd: Add a file descriptor to an fd set remove-fd: Remove a file descriptor from an fd set query-fdsets: Return information describing all fd sets Note: These commands are not compatible with the existing getfd and closefd QMP commands.

Note: 1. If you want to use gdb to process the core, please specify -p option. The reason why the -p option is not default is: a. guest machine in a catastrophic state can have corrupted memory, which we cannot trust. b. The guest machine can be in read-mode even if paging is enabled. For example: the guest machine uses ACPI to sleep, and ACPI sleep state goes in real-mode. 2. If you don't want to dump all guest's memory, please specify the start physical address and the length.

* qmp: make block job command naming consistentStefan Hajnoczi2012-04-231-3/+3
| | | | | | | | | | | | | | | | | | | | | | | | The block streaming and job commands used '_' instead of '-' for reasons of compatibility with libvirt, which already included support for the '_' naming. However, the semantics of block_job_cancel have changed and libvirt now needs to handle the new semantics. Since the old semantics were never in a QEMU release we can still rename the commands to use '-' instead of '_'. Libvirt is also happy because the new name can be used to distinguish QEMU binaries that support the latest block-job-cancel semantics from those that include a downstream block_job_cancel command. Therefore, let's apply the QAPI/QMP naming rules to the block streaming and job commands. QEMU 1.1 will be the first release with these commands so no upstream users can break. Note that HMP commands are left with '_' because that is the convention there.

Changes in v8: - rename save-devices-state to xen-save-devices-state. Changes in v7: - rename save_devices to save-devices-state. Changes in v6: - remove the is_ram parameter from register_savevm_live and sets is_ram if the device is a live_savevm device; - introduce save_devices as a QAPI command, write a better description for it; - fix CODING_STYLE; - introduce a new doc to explain the save format used by save_devices.

* | qapi: Convert migrateLuiz Capitulino2012-03-151-8/+1
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | The migrate command is one of those commands where HMP and QMP completely mix up together. This made the conversion to the QAPI (which separates the command into QMP and HMP parts) a bit difficult. The first important change to be noticed is that this commit completes the removal of the Monitor object from migration code, started by the previous commit. Another important and tricky change is about supporting the non-detached mode. That is, if the user doesn't pass '-d' the migrate command will lock the monitor and will only release it when migration is finished. To support this in the new HMP command (hmp_migrate()), it is necessary to create a timer which runs every second and checks if the migration is still active. If it is, the timer callback will re-schedule itself to run one second in the future. If the migration has already finished, the monitor lock is released and the user can use it normally. All these changes should be transparent to the user. Signed-off-by: Anthony Liguori <aliguori@us.ibm.com> Signed-off-by: Luiz Capitulino <lcapitulino@redhat.com>
