[Planetlab-users] how can i insert kernel module in the kernel of a planetlab node.

[Marc E. Fiuczynski]

Hello Murtaza,

Good question.  PlanetLab uses Linux-Vserver based isolation rather than 
VMM-based virtualization.  With the former we can "slice" a machine more 
thinly (support many more concurrent experiments), but at the cost of 
not permitting any of our users to load kernel modules, change route 
tables, etc..  The answer (for now) is that you cannot load a kernel 
module on a PlanetLab node.

In the future, it might be possible on VT based processors (or the AMD 
equivalent) to let slices start their own kvm within their slice.  Aki 
Nakao and his students at the University of Tokyo are looking into this 
option.  However, this might be a while off before being available on 
the public PlanetLab.

Hope this helps.

Marc
