No, they're not.  VMWare, RHEV (KVM-based) etc. provide features such as
seamless migration of virtual machines from one physical machine to
another, automatic restart on a different physical server if one fails
etc. that simply aren't possible with jails; and there are certain
things you still can't run reliably / safely in jails - anything that
relies on SysV IPC, for instance, such as PostgreSQL.
