Oh my, I had a major freak out about CMV status!!! Because I am negative and I read up about CMV during pregnancy and it can be nasty!
Anyway our first choice donor (brown hair, blue eyes and Caucasian, funnily enough) ended up being negative, and same blood type as me.
But if your CMV+ then it doesn't matter. If your neg, the nurses said it doesn't matter but I did consider it in our final rankings!
