How to simulate a 2 MHz crystal oscillator using LTSpice?
The two voltage sources you have for the opamp rails should be DC sources. 

Use the transient analysis type. 

Oscillators often cause problems for a simulator. Two possibilities. When they do the initial DC solve step, they fail to converge, as the point about an oscillator is that it's unstable. Or in the real world, the oscillator starts by feeding back noise, and an ideal simulator is noiseless, so there's nothing to start oscillation. 

You can fix both these problems by setting the 'initial voltage' conditions for one or more capacitors or nodes. This can break the feedback loop of an unstable circuit, and give a kick to one that needs to be started. Use the .ic directive. C1 and C2 would be ideal candidates for this intervention.

C1 and C2 look awfully big for a 2MHz oscillator, are you sure you have the right values?
