"Virtualization service (libvirt) is not active" tells me about wrong service

[stefwalter]

On Fedora 40 (and perhaps elsewhere) the Virtualization Service that the "Virtual machines" tab indicates that:

However, the service is called virtqemud

Failed to get libvirt version from the dbus API: 
Object { problem: null, name: "org.libvirt.Error", message: "Failed to connect socket to '/var/run/libvirt/virtqemud-sock': No such file or directory", toString: toString() }

and

$ sudo systemctl status libvirtd
Unit libvirtd.service could not be found.
$ sudo systemctl status virtqemud
● virtqemud.service - libvirt QEMU daemon
...

Version:

cockpit-machines-308-1.fc40.noarch

Indeed, this is currently hardcoded in the string. Our integration tests have

    def getLibvirtServiceName(self):
        m = self.machine
        return "libvirtd" if hasMonolithicDaemon(m.image) else "virtqemud"

but the runtime code doesn't.

This is a bit awkward to determine efficiently, but if we are on that page there is nothing else to do, so that's fine.

Thanks for your report @stefwalter , nice to see you back!

The issue also occurs under Fedora 39 and earlier. The issue only comes up when restarting. It takes a while and then suddenly it's gone and the services are running. Not a problem for me because I rarely restart my server, but it is annoying when the start of the VMs is delayed due to problems with libvirtd or virtqemud.
Libvirt is inactive after reboot / boot.

After manual restart av libvirt service:

But after a little while both services running fine:
