Turns out it is max_limit in /etc/nova/nova.conf.

Subject: Is there a limit on the number of VMs returned by "openstack server list --all-projects" ?

Running Rocky with a single cell; we have VMs that do not show up in “openstack server list –all-projects”

I can see them with “openstack server show” or with “openstack server list –all-projects –host” or by sourcing the credentials for their project and then “openstack server list”

If there is a limit on the number of results, that would explain it. Is anyone else seeing this? Here’s an example:

UUID: d3302d8d-3747-4665-b044-863c8d8a6855

Hostname: us01bctest-centos-57241-5

IP: 10.195.72.66

Project: vgcloud

Network: vg-network

root@us01odc-p02-ctrl1:~# source admin-openrc

root@us01odc-p02-ctrl1:~# openstack server list --all-projects|grep 10.195.72.66

root@us01odc-p02-ctrl1:~# source vg-openrc

root@us01odc-p02-ctrl1:~# openstack server list|grep 10.195.72.66
