Ulster will face Saracens, and Munster will meet Harlequins, in the quarter-finals of the Heineken Cup, with both Irish provinces playing away from home.
Ulster's clash with Sarries comes courtesy of finishing as the fifth-ranked qualifier to the Heineken Cup last eight.
Munster's trip to Premiership champions Quins is brought about by finishing as the eighth-ranked qualifier.
If Ulster win their quarter-final clash, their reward will be a home tie against the winner of the Toulon/Leicester Tigers quarter-final.
If Munster come past Conor O'Shea's Quins, they will be on the road again, travelling to face the winner of the Clermont/Montpellier quarter-final.
Leinster meet Wasps in the Amlin Challenge Cup
Leinster, who missed out on Heineken Cup last-eight qualification by one place, have qualified for the Amlin Challenge Cup.
Joe Schmidt's team will meet Wasps away from home in the last eight of the tournament.
If they sting the Wasps and reach the semis, the Dublin 4-based team will have a home tie against Gloucester or Biarritz in the last four.
