Recently libvirtd.service is not starting on boot. I have to manually
start it with systemctl start libvirtd.

Do I need to put that command in a startup script?
libvirtd.service is socket activated, so it should run automatically
when needed.  Does something not work if you don't start it manually?

virt- manager starts but says it cannot connect to anything. I have six virtual machines I use for various purposes.

systemctl status libvirtd

shows disabled and dead. After starting it manually all machines are present.

Status then shows

systemctl status libvirtd
●libvirtd.service - libvirt legacy monolithic daemon
     Loaded: loaded (/usr/lib/systemd/system/libvirtd.service; enabled; preset: disabled)

Thought

systemctl enable libvirtd

would change the preset notation but it didn't

It doesn't.  That's the system preset.  "enable" only changes the first enabled/disable option, but that overrides the preset, so it should be starting at boot if you've rebooted since changing that setting.

You can use "journalctl -b -u libvirtd" to find out what has happened.

Saw no indication that any setting had changed.

Nothing from the journal tells anything that I understand

# journalctl -b -u libvirtd
