CCU license distribution question

With a pair of 7200 chassis basically running in HA mode (as far as their vcmp guests are concerned), if one chassis had 3000 CCU licenses (for VPN use) and one had 1000 CCU licenses, what would happen if a vcmp guest currently active on the 3000 CCU license chassis had to fail over to the 1000 CCU licensed chassis? Would the only effect be shedding any connections over the 1000 CCU limit, or would it not fail over, fail over with an error, etc?
