June 1 (Reuters) - Virtualization software maker VMware Inc on Thursday reported a better-than-expected first-quarter profit and raised its full-year forecast, fueled by strong demand for its software used by companies to boost cloud computing efficiency.
Still, VMware shares fell as much as 6.6 percent in extended trading after the company released its results, but pulled back to trade down about 2 percent after VMware provided the forecast on a call with analysts.

VMware's adjusted operating margin of 28.5 percent was lower than its margin of more than 30 percent in the past three quarters.
The company, which is majority-owned by Dell Technologies Inc, said research and development costs jumped 18.2 percent, while sales and marketing expenses rose 3.7 percent.
VMware's billings of $1.67 billion was above Wall Street's estimates of $1.61 billion.
The company's revenue forecast for the current quarter was better than expected, while it raised its full-year revenue forecast.
