How to get the text console for vm?

For the vm base on the RHEL kvm host, I can get the text console from the pts device. For example: I could get the test console from '/dev/pts/1' when console tty=/dev/pts/1. But looks like this does not work for rhev-h, how could I get the text console from rhev-h?

By the way, what's the correct password to connect to the vnc server to display a vm?  I tried the password of amdin and root for the rhev-h, but neither works.

And what's the user:password to run the command in virsh for rhev-h?
