[ovirt-users] 4-2rc hosted-engine don't boot error:cannot allocate kernel buffer

Hi after successfully deployed fresh 4.2_rc with ovirt node, I'm facing with a blocking problem. hosted-engine won't boot. Reaching the console via vnc hook, I can see that it is at initial boot screen, but for any OS release available, I receive: [image: Immagine incorporata 1] then [image: Immagine incorporata 2] ​googling around, I'm not able to find suggestions. Any hints ? Thanks​ -- Roberto
