== net_nfs configuration ==
XELK 34.0.0 Virtual Machine is properly configured for the TFTP and NFS debug.
In any case, some variables has to be configured on the target and the VM itself has to be configured for respect to the network environment.
=== network adapter ===
The network adpater should be configured in '''bridge mode''' in order to allow thge the target to get the files from the VM
