in /etc/resolve.conf write nameserver

you should set dns server delete all the thing in /etc/resolve.conf and write nameserver

You should test two thing 1.test internet connection of each nod Try ping 2.test connection between each nod forexample Try ping controller Ping compute

Do you try ping

For the controller node i modified the resolv.conf and the ping works correctly and the ping also. But it always returns to the first nameserver and with this nameserver it works also correctly.

For the compute node it failed to start.

Ping When you can ping And can not ping There is problem with your DNS The other thing that you can do Go to /etc/network/interfaces And below the interface that give you internet add dns-nameservers And after that Ifdown the interface then ifup interface

ping works perfectly for me in the controller and compute nodes after each reboot of the os the nameserver in the /etc/resolv.conf take the default name

ping requires an IP address or a hostname as a parameter. is neither.

Try ping
