[one-users] Cannot start VM with XEN

Wed Jun 1 08:55:33 PDT 2011

Are you running oned as root? If you are doing so take into account
that nfs can give you some problems with nfs mounts and root
ownership. Maybe you can solve those problems adding no_root_squash to
export/mount options.

Anyway, the recommended way to run opennebula is with its own user and
having that same user/id in all the nodes.
