This indicates that iptables failed to add the stateful forwarding
rules, eg this rule
Chain FORWARD (policy ACCEPT 0 packets, 0 bytes)
pkts bytes target prot opt in out source destination
0 0 ACCEPT all -- * virbr0 0.0.0.0/0
192.168.122.0/24 state RELATED,ESTABLISHED
This says you're still missing some iptables kernel moodules.
nf_conntrack_ipv4
nf_conntrack
Are the relevant ones i believe.

Yep, manually creating virbr0 is a really bad idea & will ultimately
not work, because you still need the iptables rules which were failing
above.
