What is actually the default for the overcloud nodes SeLinux? Enforcing, permissive or disabled? I build the ipa and overcloud image myself as I had to include drivers. Is this maybe the reason why SeLinux is now enabled, but is actually disabled when using the default ipa images?</blockquote><blockquote class="quoted-plain-text" type="cite"><br></blockquote><br>From a TripleO perspective, we do not officially support selinux<br>enabled when running with CentOS. In theory it should work, however<br>it is very dependent on versions. I think you're likely running into<br>an issue with the correct version of podman which is likely causing<br>this. We've had some issues as of late which require a very specific<br>version of podman in order to work correctly with nova compute when<br>running with selinux enabled. You need 1.6.4-15 or higher which I<br>don't think is available with centos8. It should be available via<br>RDO.<br><br>Related: <a href="https://review.opendev.org/#/c/736173/" data-mce-href="https://review.opendev.org/#/c/736173/">https://review.opendev.org/#/c/736173/</a><br><br><blockquote class="quoted-plain-text" type="cite">Thanks and Best Regards,</blockquote><blockquote class="quoted-plain-text" type="cite">Oliver</blockquote><blockquote class="quoted-plain-text" type="cite"><br></blockquote><br><br></span></div></div></blockquote></div></div></body></html>
