What?
-----
Install the 'ndctl-libs', 'daxio' and 'daxio-libs' RPMs in the
'nova_compute' container it brings us the useful `virt-admin` tool.
The 'ndctl' RPM itself was added in this commit[1], but it missed to add
the above-mentioned RPMs.
PS: I'm not 100% sure if we also need 'daxio' in the 'nova_libvirt'
container too.

-- nova-compute: add ndctl to expose NVDIMMs to guests
Why?
----
Having 'ndctl-libs' and 'daxio', 'daxio-libs' is a prerequisite[2] for
Nova's virtual persistent memory feature. And Nova's code expects the
`daxio` utility (from /nova/privsep/libvirt.py):
@nova.privsep.sys_admin_pctxt.entrypoint
def cleanup_vpmem(devpath):
daxio_cmd = ['daxio', '-z', '-o', '%s' % devpath]
processutils.execute(*daxio_cmd)
