[ovirt-users] VM login info

Hi guys, After a lot of attempts, i was finally able to open a VM (centos8-cld) using virt-viewer on my mac (catalina). but i am faced with a login screen. So, where do i get this information from? or should i be using a different method to log into a vm? This goes for all of the VMs available by default. can someone please help me with this? thanks
