[libvirt-users] vnc over ssh failing

I'm using virt-manager 0.8.6 client side on Ubuntu 11.04. I can't get vnc over ssh to work to a kvm guest running on a Ubuntu 10.04 host. kvmhost:~> virsh vncdisplay testing :0 kvmhost:~> telnet 127.0.0.1 5900 Trying 127.0.0.1... Connected to 127.0.0.1. Escape character is '^]'. RFB 003.008 Client virt-manager debug: 2011-06-24 11:28:56,055 (console:923): Starting connect process for proto=vnc trans=tcp connhost=192.168.1.10 connuser=pashdown connport=None gaddr=127.0.0.1 gport=5900 gsocket=None 2011-06-24 11:28:56,120 (console:810): Viewer disconnected I can reach the console with: xtightvncviewer -via 192.168.1.10 127.0.0.1:0 Any suggestions are appreciated.
