Kellock and co will be hoping to avoid a repeat of last year's semi-final heartache when they fell to Leinster at the RDS 19-15.
And to do that the Glasgow captain is urging everyone to give their all and put the nightmare's of last season finally behind them.
"If we are to make the final then we are going to have to do it the hard way," Kellock told the Glasgow Evening Times.
"This is about delivering a performance that leaves absolutely nothing in the locker and in which we give every ounce of ourselves for every minute of the game.
"We believe we have closed the gap on Leinster from last season, but if we are to prove that point then we must get the win. Pure and simple.
"To do that a good start will be crucial. We did not get that 12 months back and spent the whole of the contest playing catch-up and if that one had lasted ten minutes longer then who knows?
"So it will be vital that when the first whistle goes we are immediately on the front foot and taking the game to Leinster and that we stay there."
