This means you don't configure a "vnc" graphic for your guest. See

# virsh help vncdisplay

For what the command does.

Except the vnc method, you might want to use text console, do like
below will work:

    1. Add console=ttyS0,115200 to guest kernel line.
    2. Add the following XML section to a domain.

<serial type='pty'>
<target port='0'/>
<console type='pty'>
<target port='0'/>

    3. # virsh start $domain
    4. # virsh console $domain
