Internet not available on Guest OS - CentOS 7
Hi Guys,
i am not sure what is the issue is but I'm not getting on my guest despite of all correct configurations.
My network configuration file is below:
Code:
[jim@test1 ~]$ cat /etc/sysconfig/network-scripts/ifcfg-enp0s3
TYPE="Ethernet"
PROXY_METHOD="none"
BROWSER_ONLY="no"
BOOTPROTO="dhcp"
DEFROUTE="yes"
IPV4_FAILURE_FATAL="no"
NAME="enp0s3"
UUID="9e228ad9-9a95-42ba-b9ce-363e163cf9e8"
DEVICE="enp0s3"
ONBOOT="yes"
PREFIX=24
GATEWAY=192.168.1.1
NM_CONTROLLED=yes
DNS1=192.168.1.1
Output of ifconfig is below:
Code:
[jim@test1 ~]$ ifconfig

What I fail to understand is, routing table does not have a default route. It is clear from the output below:
Code:
[jim@test1 ~]$ route -n
Kernel IP routing table
Destination Gateway Genmask Flags Metric Ref Use Iface
172.17.0.0 0.0.0.0 255.255.0.0 U 0 0 0 docker0
192.168.122.0 0.0.0.0 255.255.255.0 U 0 0 0 virbr0
Therefore I cannot access Internet on browser and on command for packages installation.

I just tried to disable NetworkManager and enable network daemon to see if it works.
Code:
[jim@test1 ~]$ sudo systemctl disable NetworkManager
[sudo] password for jim:
Removed symlink /etc/systemd/system/multi-user.target.wants/NetworkManager.service.
Removed symlink /etc/systemd/system/dbus-org.freedesktop.NetworkManager.service.
Removed symlink /etc/systemd/system/dbus-org.freedesktop.nm-dispatcher.service.
[jim@test1 ~]$ sudo systemctl enable network
network.service is not a native service, redirecting to /sbin/chkconfig.
Executing /sbin/chkconfig network on
[jim@test1 ~]$ sudo systemctl start network
Still no charm !!! :(
