Plugin K2 Virtuemart

Hi, MyStore is great, thanks.
I am not able to work Virtuemart and K2 together, for example K2 tags doesn't give back product tags but only article tags. Maybe it's necessary a plugin?
I read on joomlaworks about K2mart on next time.

as far as i know, k2 shop and virtuemart is 2 different shop modules that is not combined.

guess k2 community would be the right place to ask such question...
