php7.0-cli
php7.0-common
php7.0-json

How to avoid upgrading PHP?
During waking up Vagrant VM I have some troubles with the network in one work space, and it works fine in another one.
I'm trying to determine automatically DNS troubles (and fix it adding nameservers manually and disable PEERDNS), but the result is not stable:
0 ✓ vagrant 10:13:15 ~
$ ping -c 1 dl.fedoraproject.org
ping: unknown host dl.fedoraproject.org
2 ✗ vagrant 10:13:39 ~
$ time ping -c 1 dl.fedoraproject.org
PING dl.fedoraproject.org (209.132.181.25) 56(84) bytes of data.
64 bytes from 209.132.181.25: icmp_seq=1 ttl=38 time=179 ms

0 ✓ vagrant 10:16:57 ~

In the end the exit code, of course, is "0". :(
Is there any right way to determine a problem?
I have CentOS 7.2 (guest in VirtualBox, vagrant box centos/7, no GUI).
I see there is a nameserver in file:
$ cat /etc/resolv.conf
# Generated by NetworkManager
nameserver 10.0.2.3
But how to add or replace with new one?
I have done this manually directly in the network:
$ vi /etc/sysconfig/network-scripts/ifcfg-eth0
PEERDS=no
DNS1=8.8.4.4
DNS2=8.8.8.8
And it works.
But is there any way to do this through nmcli?
P.S. No nmtui installed (in a selected system).
