+++ This bug was initially created as a clone of Bug #1905154 +++ 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. [1] https://github.com/openstack/kolla/commit/f9ea23d940 -- 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) [2] https://specs.openstack.org/openstack/nova-specs/specs/train/implemented/virtual-persistent-memory.html#virtual-persistent-memory-disposal
