If you’re test driving a “minimal” Fedora install on the completely awesome VirtualBox, you may be having a little trouble getting a DHCP address while using VBox’s bridged adapter.
Here’s what you DON’T need to do- install and run the DHCP service. Resist the urge to install the dhcp package. You don’t need it.
Two easy steps should solve this problem:
- Get the eth0 interface up. It’s now called p2p1, not eth0 (info).
- Get the “network” service running on runlevel 3, the default text-only runlevel. If you’re running a desktop, you’ll also want it running on level 5 (graphical mode). By default, the network service will not be running (at least during a “minimal” install).
Using chkconfig
You can get a list of which services are running at each runlevel with chkconfig:
# chkconfig --list
Note: This output shows SysV services only and does not include native
systemd services. SysV configuration data might be overridden by native
systemd configuration.
auditd 0:off 1:off 2:on 3:on 4:on 5:on 6:off
ip6tables 0:off 1:off 2:on 3:on 4:on 5:on 6:off
iptables 0:off 1:off 2:on 3:on 4:on 5:on 6:off
lvm2-monitor 0:off 1:on 2:on 3:on 4:on 5:on 6:off
netconsole 0:off 1:off 2:off 3:off 4:off 5:off 6:off
netfs 0:off 1:off 2:off 3:on 4:on 5:on 6:off
network 0:off 1:off 2:off 3:off 4:off 5:off 6:off
saslauthd 0:off 1:off 2:off 3:off 4:off 5:off 6:off
sendmail 0:off 1:off 2:on 3:on 4:on 5:on 6:off
sshd 0:off 1:off 2:on 3:on 4:on 5:on 6:off
You’ll note that my network service is off for all runlevels in this output.
Using ifconfig
You can check to see if your p2p1 interface is up with ifconfig:
# ifconfig
You’ll likely see just one entry for “lo”, the loopback interface.
# ifconfig
lo Link encap:Local Loopback
inet addr:127.0.0.1 Mask:255.0.0.0
inet6 addr: ::1/128 Scope:Host
UP LOOPBACK RUNNING MTU:16436 Metric:1
RX packets:0 errors:0 dropped:0 overruns:0 frame:0
TX packets:0 errors:0 dropped:0 overruns:0 carrier:0
collisions:0 txqueuelen:0
RX bytes:0 (0.0 b) TX bytes:0 (0.0 b)
Bring up p2p1
To get p2p1 going, open “/etc/sysconfig/network-scripts/ifcfg-p2p1″ with your text editor. The changes to make are in blue:
DEVICE="p2p1"
BOOTPROTO=dhcp
HWADDR="04:00:21:55:71:1C"
ONBOOT="yes"
NM_CONTROLLED="yes"
Fix runlevels 3 & 5
Now we need to tell Fedora to enable networking for runlevels 3 & 5:
# chkconfig --level 35 network on
Good to Go!
Reboot your virtual machine. If your host device has internet connectivity, the virtual machine should too now. Test it by pinging yahoo.com:
# ping yahoo.com
PING yahoo.com (209.191.122.70) 56(84) bytes of data.
64 bytes from ir1.fp.vip.mud.yahoo.com (209.191.122.70): icmp_req=1 ttl=56 time=202 ms

ifconfig should now look something like below. Note that the p2p1 interface is now present and has an IP address on the local network.
# ifconfig
