It seems as though there is a problem with the grafton sanity check script. It took me a moment to spot the error below. Note the inconsistencies in the host names. changed: [obe.cyber-range.lan] (this is the correct piece of info) ping: ovir-be.cyber-range.lan (the ping portion changed the host name somehow) I'm not quite strong enough with scripting to fix it. Can anyone take a look at it?

I did change some parameters since then. I made sure I blacklisted my multipath device and dont have GPT label in the MBR. This is the most recent results of my efforts. Closer but not done quite yet.... 😉
