Thanks for the responses! Unfortunately, I'm still getting problems. After using virsh net-edit, I attempted to virt-install, and still got the same error. When I run 'virsh net-start default', I get this error: error: Failed to start network default error: failed to add iptables rule to allow DHCP requests from 'virbr0' None of the solutions I have found on Google have a fix for this. Any ideas?
