Description of problem: This is on a hosted KVM instance. I cannot say more about the hosts KVM except that I think it is a widely used provider and that the bootup worked fine with Fedora 32, the original install. After updating to Fedora 33 the eth0 interface does not come up anymore. systemctl shows that systemd-entworkd.socket is waiting (or something like this, I only have a webconsole available which does not provide copy&paste). Once I run systemctl restart systemd-networkd after logging in to the console everything is fine. The only noteworthy detail is that the system gets a routable IPv6 address as well. I updated the system to Fedora 34 meanwhile and the problem persists. On request I can run more tests and provide more logs. Version-Release number of selected component (if applicable): 246.10-1.fc33 248~rc4-2.fc34 How reproducible: always for me Steps to Reproduce: 1.install Fedora 32 in this KVM guest 2.update in place to Fedora 33 3.reboot Actual results: only lo interface running Expected results: all network interfaces running Additional info:
Is this using systemd-networkd or NetworkManager to configure the network? Please at least paste 'ip a' and 'networkctl status "*"'. Full logs from the boot would be useful too.

It complains about DHCP but that service does work, I can immediately after the bootup reliably restart networkd.
Oh, OK. So systemd-networkd is not running, most likely because it is not enabled. I guess we screwed up the scriptlet to set enablement when the package was split out.

This should really be fixed, seems like a bad bug. BTW, this is the server edition of Fedora, in case it makes a difference. I updated my desktop machine back when from earlier Fedora versions to 33 and cannot recall any problem like that. The desktop uses the desktop edition.
(In reply to Ulrich Drepper from comment #8) > This should really be fixed, seems like a bad bug. I determined I had the same problem on another machine. There, though, the IPv4 address was for some reason configured but not the IPv6 address. The result were long connection times until the IPv6 connection timed out.

The > result were long connection times until the IPv6 connection timed out. To give people more chances to discover this solution: on yet another machine the network interfaces came up (IPv4 and IPv6) but systemd-resolved never remembered the non-standard settings it can derive from the DHCP requests. I added special rules and only after enable systemd-networkd are they now remembered over a restart.
