KVM/libvirt VM console access?

[asianscion]

I know this thread is old but I was searching for this exact problem and was having a tough time with it.

Here is the solution I found:

Setup:

Macbook Pro running Mac OS X 10.7.3
Dell R210 Server running Ubuntu 10.04 with KVM-QEMU installed

Settings on Mac

MacBook-Pro:~ user$ cat ~/.ssh/config
ServerAliveInterval=60
ForwardX11=yes
MacBook-Pro:~ user$

Command on server

root@vmhost1:~# virt-viewer name-of-VM

If you get something along the lines of

(virt-viewer:2399): Gtk-WARNING **: cannot open display: localhost:10.0

Log out and log back in. Try virt-viewer again, and it should work.
