QEMU enters in this state when the guest suspends to ram (S3). This is important so that HMP users and QMP clients can know that the guest is suspended. QMP also has an event for this, but events are not reliable and are limited (ie. a client can connect to QEMU after the event has been emitted). Having a different state for S3 brings a new issue, though. Every device that doesn't run when the VM is stopped but wants to run when the VM is suspended has to check for RUN_STATE_SUSPENDED explicitly. This is the case for the keyboard and mouse devices, for example. Signed-off-by: Luiz Capitulino <lcapitulino@redhat.com> Acked-by: Gerd Hoffmann <kraxel@redhat.com>

|
# composition tree, the partial path is matched as an absolute path.

# The block streaming operation is performed in the background until the entire
|
|
# backing file has been copied. This command returns immediately once streaming
|
|
# has started. The status of ongoing block streaming operations can be checked
|
|
# with query-block-jobs. The operation can be stopped before it has completed
|
|
# using the block-job-cancel command.
|
|
#
|
|
# If a base file is specified then sectors are not copied from that base file and
|
|
# its backing chain. When streaming completes the image file will have the base
|
|
# file as its backing file. This can be used to stream a subset of the backing
|
|
# file chain instead of flattening the entire image.
|
|
#
|
|
# On successful completion the image file is updated to drop the backing file
|
|
# and the BLOCK_JOB_COMPLETED event is emitted.
