[Users] VM Export and import problem

I have exported a couple of VMs to an export domain and did a new setup of ovirt-engine. Importing is no problem as long as I import all machines first and then create new VMs. If I first create a couple of VM's and then try to import I get the error that the mac address is already in use. No problem, but I don't see an option to change the mac address of the to be imported machine so can't import it. Finding the active VM with the offending mac address is possible but not really the way to go IMHO. Is there an other route to get those VM's imported? Thanks, Joop van de Wege -- irc: jvandewege
