That's not the actual error message (because the actual message wouldn't
mis-spell directory), but is generally the message you see when libvirtd
is not running. Are you sure you got your self-built libvirtd installed
and running correctly?

I'm not familiar enough with libvirt on ubuntu to know if this is a
problem. If you are going to replace your distro's old libvirt with a
newer self-built version, it is STILL helpful to install your distro's
libvirt first, to make sure that all the distro-specific tweaks (such as
setting up /etc/init.d/ and so forth to run libvirtd as a daemon) are in
place.
Usually, Ubuntu uses upstart. So, there should be a
/etc/init/libvirt-bin.conf which defines the libvirt daemon upstart
job.
I'm not sure whether the configure script detects upstart and installs
the upstart files automatically, though.

I guess that you tried to run "sudo /usr/sbin/libvirtd start"?! This
won't work as "/start" is not a valid non-option command line argument
as the error message already told you.
According to the tutorial blog that you linked to, it seems like you
would use 'sudo initctl start libvirt-bin' and not 'sudo
/usr/sbin/libvirtd/start' to start libvirtd
"sudo start libvirt-bin" is a shortcut method which does the same, BTW.
