As perfTerm noted, DV stands for Domain Validation. DV is where, basically, you prove ("validate") that you own the domain you're requesting a certificate for, typically by being able to receive an e-mail sent to one of the contacts listed in WHOIS for the domain.
This is similar to Google requiring you to create a file in the root directory of a web site or creating a TXT RR (with a specific value) in the DNS zone for a domain for Google Analytics (if you've ever done that).
