When virt-network flag is enabled for the app-emulation/libvirt package it requires net-dns/dnsmasq[script], which is not enough and is causing the following issue on libvirtd startup: internal error: Child process (VIR_BRIDGE_NAME=virbr0 /usr/sbin/dnsmasq --conf-file=/var/lib/libvirt/dnsmasq/default.conf --leasefile-ro --dhcp-script=/usr/libexec/libvirt_leaseshelper) unexpected exit status 1: dnsmasq: bad command line options: unsupported option (check that dnsmasq was compiled with DHCP/TFTP/DNSSEC/DBus support) building net-dns/dnsmasq with dhcp flag enabled fixes this startup problem: Jan 07 07:39:05 localhost dnsmasq[1316]: started, version 2.82 cachesize 150 Jan 07 07:39:05 localhost dnsmasq[1316]: compile time options: IPv6 GNU-getopt no-DBus no-UBus no-i18n no-IDN DHCP no-DHCPv6 no-Lua no-TFTP no-conntrack ipset no-auth no-DNSSEC no-ID loop-detect no-inotify no-dumpfile Jan 07 07:39:05 localhost dnsmasq-dhcp[1316]: DHCP, IP range 192.168.122.2 -- 192.168.122.254, lease time 1h Jan 07 07:39:05 localhost dnsmasq-dhcp[1316]: DHCP, sockets bound exclusively to interface virbr0 Jan 07 07:39:05 localhost dnsmasq[1316]: reading /etc/resolv.conf Jan 07 07:39:05 localhost dnsmasq[1316]: using nameserver 127.0.0.53#53 Jan 07 07:39:05 localhost dnsmasq[1316]: read /etc/hosts - 2 addresses Jan 07 07:39:05 localhost dnsmasq[1316]: read /var/lib/libvirt/dnsmasq/default.addnhosts - 0 addresses Jan 07 07:39:05 localhost dnsmasq-dhcp[1316]: read /var/lib/libvirt/dnsmasq/default.hostsfile However, given that libvirtd lists DHCP/TFTP/DNSSEC/DBus in the startup error, it might be necessary to enable more flags, i.e. tftp, dnssec and dbus. I haven't been able to confirm or deny if that's the case yet, but as I will provide more details (or probably create additional bug reports) if/when I have them.
Okay, got some further insights. Upon creating a virtual network getting: Jan 07 09:42:44 localhost dnsmasq[5673]: unsupported option (check that dnsmasq was compiled with DHCP/TFTP/DNSSEC/DBus support) at line 15 of /var/lib/libvirt/dnsmasq/vmnet.conf Jan 07 09:42:44 localhost dnsmasq[5673]: FAILED to start up Jan 07 09:42:44 localhost libvirtd[1203]: internal error: Child process (VIR_BRIDGE_NAME=virbr1 /usr/sbin/dnsmasq --conf-file=/var/lib/libvirt/dnsmasq/vmnet.conf --leasefile-ro --dhcp-script=/usr/libexec/libvirt_leaseshelper) unexpected exit status 1: dnsmasq: unsupported option (check that dnsmasq was compiled with DHCP/TFTP/DNSSEC/DBus support) at line 15 of /var/lib/libvirt/dnsmasq/vmnet.conf the vmnet.conf configuration file that's generated by the libvirtd is: ##WARNING: THIS IS AN AUTO-GENERATED FILE.

Changes to this configuration should be made using: ## virsh net-edit vmnet ## or other application using the libvirt API. ## ## dnsmasq conf file created by libvirt strict-order port=0 pid-file=/run/libvirt/network/vmnet.pid except-interface=lo bind-dynamic interface=virbr1 dhcp-option=3 no-resolv ra-param=*,0,0 dhcp-range=192.168.255.2,192.168.255.254,255.255.255.0 dhcp-no-override dhcp-authoritative dhcp-lease-max=253 dhcp-hostsfile=/var/lib/libvirt/dnsmasq/vmnet.hostsfile and line 15 is about ra-param, which requires IPv6 to be enabled, so we need an ipv6 flag.
Is it now [ipv6,script] rather than [ipv6,dhcp,script]? Feel free to edit the summary yourself (haven't tested myself).
Sorry, could have been clearer! We need all: script, dhcp and ipv6. Possibly others, but I haven't yet being able to verify that. net-dns/dnsmasq[ipv6,dhcp,script] was enough for now, but I will be testing other use cases as time permits and see if more is needed.
