[one-users] OpenNebula 2.2 Cluster Error

[Clément Berthelot]

Well my bad again guys for asking for help too quickly. Found the error. On the node when I edited the /etc/sudoers file, I had followed the instruction and created the two %xen……. lines. But my group was actually not called xen but cloud, changed the two lines and now it works like a charm !

Thanks you

Clement

However, when I add a host on the frontend (onehost create 10.1.1.1 im_xen vmm_xen tm_ssh), its status is set to on for a few seconds and then it goes to ERROR. I checked the oned.log file and it shows this:
