RH318

Hi all

Going through the first guided exercise in chapter 3 of the RH318 course, my RHEV-H node is in a 'non-operational state'. The text says:

'If the RHEV-H host enters a Non-Operational state, reboot the RHEV-H host and check its BIOS settings. Make sure that “Execute Disable Memory Protection Technology” is enabled.'

How do I do this?

Thanks
