virt-launcher: create dedicated cpu guests paused

If guest is configured with dedicated CPUs and emulator thread isolation, then start it paused. This allows the cgroup configuration of housekeeping cgroup to happen before guest is allowed to execute. The state machine will naturally unpause the guest afterwards (if the user requested guest state is unpaused). Signed-off-by: Marcelo Tosatti <[email protected]>
