hi Mr Rich.
I did it :)
I can mount, modify the file system on the running guest and the guest update properly :)
Although I still failed to run the guestfsd daemon inside the guest machine but everything worked properly. I don`t understand why. Can you explain?
By the way, I used guestmount to mount the running guest.

Thanks :)

As you've pasted it above, the clause is wrong.  It is missing
spaces in important places (eg. mode='bind'path should be mode='bind' path)

Start with this simple example:

       <channel type='unix'>
         <source mode='bind' path='/tmp/socket'/>
         <target type='virtio' name='org.libguestfs.channel.0'/>
       </channel>

Make sure you copy it accurately.

Use 'virsh edit <Guest>' to edit the guest XML, and
'virsh domxml <Guest>' to check that the clause you tried to
add is present.

Rich.
