VM what is default user/password

Hi, I have imported VM 5.02, and once started I have the login on the console.
How do I configure it? what is the default user/password?
Thank ou.,

i have tested this here on Virt-Manager (Download of the KVM-Image). If started the imported VM, it ask me during the setupprocess of a new administrator/root password. After end of the setup and reboot, i can login with this user information.
