[ovirt-devel] Any info for analyzing Ovirt??

Dear Ovirt I aminterested in developing VDI using Ovirt. I need to know how Ovirt works in coding level because I might have to change or verify the Ovirt code. So, if you send me any info, such as UML(Unified Model Language), it would be very thankful. Hope for your help Sincerely yours Hyunsoo Lee.
