Hello,
I must tell you that you can have an UML ubuntu 10.04 in the
cloonix environment at http://cloonix.net
And the cloonix environement has a slirp integrated inside its
own network and you can surf on internet from your UML ubuntu
plug-and-play.
Note: due to libssl used in cloonix, most users have to
recompile the cloonix tree and as the cloonix also supports
KVM, the following packages are needed for good compilation:
yum install gtk-vnc-devel
yum install vte-devel
or
apt-get install libgtk-vnc-1.0-dev
apt-get install libvte-dev
Note: The slirp in cloonix has been recoded, but comes from the
official slirp.
