I understand but why it wasn't started in the first time?

help suggest otherwise:
# dhcpcd --help | grep "\-m"
                [-l, --leasetime seconds] [-m, --metric metric]

version is:
dhcpcd 8.1.9

what is the expected cmd? dhcpcd -t 0 -m veth?

the tap device is created by libvirt, I just changed the name from vnet0 to veth
the script name is /etc/init.d/net.veth

I'm not sure gentoo supports this feature out of the box.
