Every time I run dnf, I get this:
========= [root@vmhost2 ~]# dnf upgrade CentOS Linux 8 - AppStream 70 B/s | 38 B 00:00 Error: Failed to download metadata for repo 'appstream': Cannot prepare internal mirrorlist: No URLs in mirrorlist =========
I tried disabling the repository, but that only gives me exactly the same error for the baseos repository. I doubt it is a problem in the .repo files. Something else is going on.
Ping to mirrorlist.centos.org works on both ipv4 and ipv6, so I know that both name resolution and network connectivity are working.
Thanks!

That's because you are still on CentOS 8 not 8-stream. The C8 repositories are now empty. (The equivalent repo for 8-stream is labelled "CentOS Stream 8 - AppStream".)
To move to 8 Stream, see https://centos.org/download/
You will also probably soon get some recommendations to not move to 8 stream and to use one of the other clone distros ...
P.
Hmmmm..... I thought I was already on stream, but apparently not. /etc/redhat-release says it is not stream.
I looked for a method to upgrade. Found some notes at techrepublic. The first step is to install centos-release-stream, which fails. So what is the method for doing an upgrade?
Bare metal reinstall is NOT an option. If that is the only way to do it, then I will just let this system run for a few years with no updates.

I gave you the link for the official way of doing it:
Click on the "CentOS Stream" purple bit at the top, then on the '8' purple bit. Then scroll down to "Converting from CentOS Linux 8 to CentOS Stream 8". If your machine hasn't been updated for a while, you might need to add '--allowerasing' to the comand line to swap the distros.
If it doesn't work, then please let the list know any error messages so someone can help you.

Ah, additional details. Thanks! The download is started. Running REALLY slow (like 24kb per second!) but it is running. I am not in a big hurry.

I'm also trying to upgrade my CentOS Stream 8 system, and am getting super slow download speeds when the initial metadata is being retrieved... approx. 30kB/s.
I know on older CentOS systems, you could Ctrl-C and yum would move onto a different (hopefully faster) mirror, but now Ctrl-C just stops dnf altogether, and if I reissue the "dnf upgrade" command, it again slows down to a crawl.
Is there some setting for a minimum bandwidth threshold or some other way to diagnose some really slow mirror?
thanks, Greg

Add the fastestmirror directive to /etc/dnf/dnf.conf
That won't give you a minimum bandwidth but it will find what it thinks is the fastest mirror to download from. (Not guaranteed to be the fastest since it measures ping response time at the start and picks from there, but it's more than nothing.)
The download eventually finished for me. It was slow, but it did finish.
The install worked without a hitch, everything rebooted and now the system reports it is on Stream. All the VirtualBox guests came back up, too.
Thanks!

As mentioned by Pete Biggs, you can also move to another RHEL clone, which have all the updates, for example Rocky Linux, or Alma Linux. There is a script to do it : https://docs.rockylinux.org/guides/migrate2rocky/
It is not recommended to not have any updates for years...
