Create container rootfs
For Fedora:

sudo chroot workstation
passwd
exit
Be sure to disable selinux:
sudo setenforce 0
Start container:
sudo systemd-nspawn -D /home/iaroki/workstation -b --network-bridge br0
Setup network
Login with root and configure network interface:
[root@workstation ~]# ip addr add 10.10.10.100/24 dev host0
[root@workstation ~]# ip link set host0 up
[root@workstation ~]# ip route add default via 10.10.10.1
[root@workstation ~]# echo nameserver 1.1.1.1 > /etc/resolv.conf
Or write systemd network file:
/etc/systemd/network/20-wired.network
[Match]
Name=host0
[Network]
Address=10.10.10.100/24
