The libvirt backend uses a network bridge on the host to setup the
networking in the guest, which is enabled by default in virt-builder.
OK, now it is clear why bypassing libvirt avoids this issue.
So maybe I'm missing some libvirt package required for creating the
bridge?
libvirt is installed by vdsm, which requires:
libvirt-client
libvirt-daemon-config-nwfilter
libvirt-daemon-kvm
libvirt-lock-sanlock
libvirt-python

"used to work" which version with?
What was available in Fedora 28 2-3 month ago. The vm used for
running this was lost, so I don't have more specific info.
And which version are you using now?
$ rpm -q libguestfs-tools-c
libguestfs-tools-c-1.38.4-1.fc28.x86_64
