Why hangs the command ls rbd on Ubuntu?

Talking about RADOS Block Device. After picking up a Ceph cluster on Vmware + Ubuntu trying to execute a command or rbd ls rbd create, the command is run and is not completed. While not doing anything judging by the CPU, and hangs a bunch rbd forks of the idlers. Anyone faced with?

Raise the cluster for the first time, seems to rise:
