Currently no command can be sent to a qemu process while another job is active. This patch adds support for signaling long-running jobs (such as migration) so that other threads may request predefined operations to be done during such jobs. Two signals are defined so far: - QEMU_JOB_SIGNAL_CANCEL - QEMU_JOB_SIGNAL_SUSPEND The first one is used by qemuDomainAbortJob. The second one is used by qemudDomainSuspend for suspending a domain during migration, which allows for changing live migration into offline migration. However, there is a small issue in the way qemudDomainSuspend is currently implemented for migrating domains. The API calls returns immediately after signaling migration job which means it is asynchronous in this specific case. Signed-off-by: NJiri Denemark <jdenemar@redhat.com>
