If it says excluding misdemeanors, then you can exclude the misdemeanor DUI. Summary offenses probably include those without probation, such as infractions like traffic tickets. Good luck.
The job application instructs you to exclude misdemeanors, so follow the instructions and don't mention your misdemeanor convictions. It appears based on this question that this employer is only interested in felony counts.

The question is asking about crimes other than misdemeanors, which means the employer only wants to know if you've ever been convicted of a felony. If you have never been convicted of a felony, you can say no to this with a clear conscience.
A first or second offense DUI is not a felony in Virginia. A third or subsequent DUI within ten years is a felony. If you are not certain whether you have been convicted of a felony, call the court where you were convicted and ask them. But, seriously, who gets convicted of a felony and can't remember it?
