We currently have 5 vms, on Fedora 32, 37 (labeled last-latest) and 38 (labeled latest).

I connected a new host with Fedora 38 in #3352:

https://ci.nodejs.org/manage/computer/test-digitalocean-fedora38-x64-1/

Unfortunately, one test on nodejs/node@main fails consistently:

https://ci.nodejs.org/job/node-test-commit-linux/nodes=fedora-latest-x64/52059/

I connected the machine to the CI and it picked up https://ci.nodejs.org/job/node-test-node-addon-api-new/nodes=fedora-latest-x64/7737/

Agent is now definitely connected: https://ci.nodejs.org/computer/test-digitalocean-fedora38-x64-1/
I'll monitor the jobs it takes over the next few days.

We now have two fedora38 machines in CI. I disconnected https://ci.nodejs.org/computer/test-digitalocean-fedora34-x64-2/ and will replace it with fedora37 when I get back to this.
