I have given static IP on my Vmware CEntoS virtual machine.

My internet was working fine. but after restarting machine

This is my ifcfg-eth0 file

DEVICE="eth0"
NM_CONTROLLED="no"
#ONBOOT="no"

NM_CONTROLLED="no"
ONBOOT="yes"
#BOOTPROTO="dhcp"
BOOTPROTO="static"
IPADDR=192.168.0.200
NETMASK=255.255.255.0
GATEWAY=192.168.0.1
PEERDNS="no"

DNS1=8.8.8.8
DNS2=8.8.8.4

I am trying to ping the gateway 192.168.0.1 and i get

PING 192.168.0.1 (192.168.0.1) 56(84) bytes of data.
From 192.168.0.200 icmp_seq=2 Destination Host Unreachable
From 192.168.0.200 icmp_seq=3 Destination Host Unreachable

which things can cause error

UPDATE: I am using vmware workstation 10 on window 7 as host with bridged network state

I tried Adding second network card in bridges mode and this is result. etho is NAT and eth1 is bridged

sudo service network restart

  • The host is unreachable, CentOS isn't recognising it has a network connection. Have you tried ifup eth0 and/or service network start?

Reset to default

You have to make sure what kind of network mode your guest is in. It is NAT mode by default,so the IP address should be got from a DHCP server, A.K.A the virtual adapter in your host machine. So you may comment all the configuration about static IP, and set it to DHCP mode, then restart your adapter.

  • try this my reference. If you want to use /etc/resolv.conf then PEERDNS

  • Now I have the answer. When in bridge mode, your guest should be configured as your host because they are in the same net, so check your host's configuration first.

try this my reference I haven't seen DNS1=8.8.8.8 here before, if you want to use /etc/resolv.conf then PEERDNS="no", if you want to overwrite /etc/resolv.conf then PEERDNS="yes", However, in both situations there is no DNS1= item.

You need to configure an interface configuration for eth1. Take the configuration you posted and save it as ifcfg-eth1. Change the DEVICE line to match eth1 and make sure you configure an IP address that is unused.
