Hi,

It seems that your drivers are loaded without errors. However, the
transfer driver  (used in prolog) is tm_nfs but OpenNebula is trying
to use vmm_xen. Maybe the host was not created with the right drivers.
The syntax is:


onehost create <hostname> <im_mad> <vmm_mad> <tm_mad>

in your case

onehost create node01 im_xen vmm_xen tm_nfs

you can check onehost show node01, and check the drivers...

Cheers
