Debug output

Debug: https://gist.github.com/fabstao/2b2fa5420180dcaf9996e83e0f250a0b

Expected behavior

What should have happened? Having two domains (VMs) running

Actual behavior

What actually happened?

Got error:

Call to virConnectListAllNetworks failed: Failed to connect socket to '/var/run/libvirt/virtnetworkd-sock-ro': No such file or directory

Steps to reproduce

1. Create Vagrantfile as included
2. run: vagrant up as regular user

I was also facing this very issue and I am not sure what changed in recent updates.

I saw that this daemon was in an "inactive" state:

$ sudo systemctl status virtnetworkd
○ virtnetworkd.service - Virtualization network daemon
     Loaded: loaded (/usr/lib/systemd/system/virtnetworkd.service; disabled; vendor preset: disabled)
     Active: inactive (dead)
TriggeredBy: ● virtnetworkd.socket
             ○ virtnetworkd-ro.socket
             ○ virtnetworkd-admin.socket
       Docs: man:libvirtd(8)
             https://libvirt.org

So started and enabled it:

sudo systemctl enable --now virtnetworkd

Now it is working fine:

$ sudo systemctl status virtnetworkd
● virtnetworkd.service - Virtualization network daemon
     Loaded: loaded (/usr/lib/systemd/system/virtnetworkd.service; enabled; vendor preset: disabled)
     Active: active (running) since Mon 2022-01-31 12:09:16 IST; 9s ago

             ● virtnetworkd.socket

             https://libvirt.org

Now vagrant up works for me.

Thanks! Didn't work for me, now it is complaining about trying to use libvirt at all
