Cannot access KVM using virsh console after KVM rebooted or shut off

[Daniel Romero]

Hi,

Try to enable vnc on your vm, then try to connect using that protocol and see what happens. 

You can use chicken of the vnc os x client to connect and be sure your host machine have the right ports open for incoming vnc connections (start at 5900). 

Best regards,
