Hi again,
I won't have access again to the system till Monday so I will test it then,
but a colleague of mine just told me (he is just trying the same set up
with similar issues):
when virtual machine is booting on the compute node, on the controller node
i can see the following:
22:18:39.500044 IP 10.10.10.2 > 10.10.10.1: GREv0, key=0x1, length 354: IP

10.10.10.1 - controller node
10.10.10.2 - compute node
looks like controller accepts requirest, but doesn't know what to do with it
Kind regards.
