Virtual Feats are granted regardless of whether one qualifies for them or not.
For example, it's clearly labelled under the Improved Trip for Monks that they receive the Feat even if they do not have the requisite INT to normally have Expertise, or have Expertise itself.
This is explained first in S&F in detail (I believe) and then again in all the other splatbooks.
Furthermore, let me quote from the SRD:
"When wearing light armor or no armor, a ranger can fight with two weapons as if he or she had the feats Ambidexterity and Two-Weapon Fighting. The ranger loses this special bonus when fighting in medium or heavy armor, or when using a double-headed weapon (such as a double sword). "
Bolded emphasis mine.
