Should ports created by ironic have PXE parameters after deployment?

Thanks Julia

While investigating this further I found that if I delete the host then re-discovery it the issue goes away.  So something I’ve done in my deployment has broken this on the other hosts.   I need to open up the database and start digging around the tables to figure out if there is any differences in the two enrolled host.

Yes I use kolla-ansible which natively deploys the ironic dashboard.  It seems to work pretty good but its very noisy with errors during host state change constantly throwing errors on the page even though things are progressing as normal.

I have several environments using Kolla-Ansible and this one seems to be the only behaving like this. My neutron-dhcp-agent dnsmasq opt file looks like this after a host is deployed.
