Need the output of 'systemctl status networking.service'
Using the console I could find the culprit: the datacenter uses ethernet switches that filter MAC addresses, so I had to set the virbr10 mac address to the same as eno1 interface. It now works with this configuration (those are not the real IP addresses):
iface eno1 inet manual
auto virbr10
iface virbr10 inet static
bridge_ports eno1
bridge_stp off
bridge_fd 0
bridge_waitport 0
address 2.4.6.8
netmask 255.255.255.224
gateway 2.4.6.1
post-up /usr/sbin/ip link set virbr10 address 0c:c4:7a:00:36:06
and similar configuration is in place in the guest for its
virtio-emulated network interface card.
