If the update sequence for automated updates contains an update which requires a host reboot and a hotfix with an immediate toolstack restart (after-apply-guidance=restartXAPI and guidance-mandatory=true), then XenCenter should do an immediate host reboot after applying the hotfix that required the immediate toolstack restart (as doing a toolstack restart when a host reboot is required is potentially risky) Signed-off-by: Mihaela Stoica <mihaela.stoica@citrix.com>
