Qemu nic show "NO-CARRIER" after installation

I install a new arch linux system in qemu today. The installation is ok, I can access the internet when I install the system.
But dhcpcd say "no interfaces have a carrier" after I reboot and login to the new system. I run command "ip link show dev enp0s2", it show me:
2: enp0s2: <NO-CARRIER, BROADCAST,MULTICAST,UP> mtu 1500 qdisc fq_code1 state DOWN mode DEFAULT group default qlen 1000

Do I miss anythings?

Have you enabled the interface?

I use it to look at funny pictures of cats and to argue with strangers.

Yes, you can see there is "UP" in ip command's output

Re: Qemu nic show "NO-CARRIER" after installation

In the installation system, dmesg show me:
[    2.536599] e1000: Intel(R) PRO/1000 Network Driver - version 7.3.21-k8-NAPI
[    2.536600] e1000: Copyright (c) 1999-2006 Intel Corporation.
[    2.846300] e1000 0000:00:02.0 eth0: (PCI:33MHz:32-bit) 52:54:00:12:34:56
[    2.846313] e1000 0000:00:02.0 eth0: Intel(R) PRO/1000 Network Connection
[    6.311608] e1000 0000:00:02.0 enp0s2: renamed from eth0
[    7.233461] e1000: enp0s2 NIC Link is Up 1000 Mbps Full Duplex, Flow Control: RX

But in the installed system, only the first 5 lines present.

My host system is ubuntu 16.04 with kernel 4.10.0-32-lowlatency, qemu 2.10.0-rc2. The kernel version of arch linux installation iso is 4.12.3, the kernel version of installed arch system is 4.12.6

What was the specific command you used to start Qemu?
