SSH connections:-

2.Dom0 to Free BSD DomU
3.HVM S10U4 DomU to HVM FreeBSD 7 DomU

To install Gnome Desktop run:-

# pkg_add -r gnome2
 

Enable Gnome Desktop by adding gdm_enable="YES" to /etc/rc.conf and
reboot DomU.


GNOME may also be started from the command-line by properly configuring a file named ~/.xinitrc. If a custom .xinitrc is already in place, simply replace the line that starts the current window manager with one
that starts /usr/local/bin/gnome-session instead.
Next, type startx, and the GNOME desktop environment will be started.
