[Netkit.users] netkit inside a fedora Linux Vserver

[Massimo Rimondini]

Dear Saverio,

the output you are reporting mixes up messages from the virtual machine
and from the host. The script_utils error must come from the host,
because no such script exists inside virtual machines.
In order to assess the point (during vm startup) at which the error
occurs, you may want to run vstart again with --con0=none.

Now, the error seems to be caused by some external command run by the
vstart script: if you check line 243 of script_utils, you can see that
its purpose is to invoke external tools.
At this point, I suspect (but really it is just a suspect) that the
problem may lie in the uml_switch. If you can, I would suggest using the
standard uml-utilities package in the Planetlab node, which means
installing it (probably) and adjust the PATH variable to seek in system
binaries first and then in Netkit directories.

Regards,
Massimo.
