* Ireland turns spotlight back onto euro zone debt
* Disappointing Cisco outlook weighs on Wall St
* Gold erases gains as dollar strengthens

NEW YORK, Nov 11 (Reuters) - The euro fell on Thursday on concerns about Ireland's ability to repay its debt while U.S. stocks fell on doubts about corporate profits after a technology bellwether gave a dismal earnings outlook.
Gold erased initial gains and fell as the dollar rose against major currencies. Oil prices were little changed as news of strong Chinese demand was offset by the rise of the greenback.
Yields on 10-year Irish bonds rose to a record high over comparable German debt as investors speculated Ireland will soon need financial help to service its debt. For details, see [ID:nLDE6AA0MK].
Ireland's Finance Minister Brian Lenihan admitted the surge in borrowing costs had become "very serious," but European officials denied for a second day that Dublin was seeking financial aid -- a pattern similar to one six months ago when Greece needed an EU/IMF bailout.
"Europe never fully addressed these problems, and it's clear solvency issues in Ireland have not been resolved," said Marc Chandler, global head of currency strategy at Brown Brothers Harriman, who sees the euro at $1.33 by the end of 2010.

"The euro can't sustain even modest upticks right now, and a fall below $1.3650 could open up another two-cent decline," Harriman added.
The dollar strengthened against major currencies, with the U.S. Dollar Index <.DXY> up 0.54 percent. Also supporting the greenback was a U.S. think tank report saying the Federal Reserve may scale back its latest plan to buy government bonds.
