Virtualbox centos no eth0

Question

just installed a fresh centos-minimal and i can not get bridged network to work or any of the networks not even in host-only mode. when you run ifconfig there is no eth0 only a lo,

also when you cat /etc/sysconfig/network-scripts/ifcfg-eth0

DEVICE="eth0"
HWADDR="08:00:27:FE:D5:10"
NM_CONTROLLED="yes"
ONBOOT="no"

Did you try using `ifconfig -a` instead of `ifconfig`? The former will display information about adapters that aren't in the 'UP' state. — nearora, May 31 '12 at 03:50

As cpuguru said, you need to config the network. So login on your centos and execute:

vi /etc/sysconfig/network-scripts/ifcfg-eth0

As Chris R explained, you should edit the contents of that file to end up having this:

DEVICE="eth0"
HWADDR=MAC Address*System MAC*
NM_CONTROLLED="no"
ONBOOT="yes"
BOOTPROTO="dhcp"

Then save (escape :wq INTRO) and then reboot:

reboot

If you have cloned a VM or otherwise changed the MAC you may need to delete `/etc/udev/rules.d/70-persistent-net.rules` ... please correct me if I am wrong! – KCD Aug 08 '12 at 06:41

I had a similar issue with CentOS on Hyper-V the other day.

The solution seemed to be to fire up a terminal, su to root and run 'system-config-network' to enable CentOS to use the virtual nic.

I am using centos 6 i got eth0 to show in ifconfig but it has no IPs or anything. – Chris R Jan 15 '12 at 01:38
Try changing your ifcfg-eth0 script parameter from ONBOOT="no" to ONBOOT="yes" – cpuguru Jan 15 '12 at 01:43
Thank you had to change my ifcfg-eth0 script to DEVICE="eth0" HWADDR=MAC Address*System MAC* NM_CONTROLLED="no" ONBOOT="yes" BOOTPROTO="dhcp" – Chris R Jan 15 '12 at 01:50
