Hello, To allow (KVM) virtual machine guests running on a Fedora 16 host connect to host services one could open system-config-firewall, define "virbr0" and "vnet0" as trusted interfaces, and be done. On Fedora 18, the firewall-config GUI does not provide any means to work with network interfaces. Moreover, # firewall-cmd --zone=trusted --add-interface=virbr0 # firewall-cmd --zone=trusted --add-interface=vnet0 works, but only until the next host reboot, while # firewall-cmd --permanent --zone=trusted --add-interface=virbr0 # firewall-cmd --permanent --zone=trusted --add-interface=vnet0 just brings up a man page (no error message???) This is firewalld-0.2.12-1.fc18.src.rpm Andrei PS. I am aware of #882736, which reports that the patch to firewalld allows to restore VM guest functionality by setting default zone to "trusted". That workaround is unsatisfactory because of its potential to create security problems.
