Hi I have installed virtual box 4.1.20 r80170

My router is dlink DIR-615

my host os is centos 6.3 64 bit

my guest os is oracle linux 5.8 64 bit

initally I have configured to use NAT for the network settings for my virtual box guest which is Oracle Linux 5.8.

at that time i was able to access the Internet from the guest Os.

when I change to bridged adapter I neither able to ping

from host to guest
from guest to host

may I know what's wrong?

how should I trouble shoot this?

my eth0 configurations on the guest os is as follow:

#Intel Corporation 82540EM Gigabit Ethernet Controller
DEVICE=etho0
BOOTPROTO=static
HWADDR:08:00:27:08:19:50
ONBOOT:yes
DHCPHOSTNAME=source.localdomain
IPADDR=192.168.0.11
NETMASK-192.168.0.1
TYPE=Ethernet
USERCTRL=no
IPV6INIT=no
PEERDNS=yes


my /sbin/ifconfig settings on the host Os is as follow:


[oracle@localhost ~]$ /sbin/ifconfig

I've done a dmesg while pinging from guest to host here's the partial output:


spurious NAK ON isa0060/serio0
some program might be trying to acces hardware directly
e100:eth0 NIC link is up 1000 Mbp
Full Duplex, Flow Control: RX
ADDRCONF (NETDEV_UP) eth0: link is not ready
ADDRCONF (NETDEV_CHANGE): eth0 becomes ready
eth0: no IPv6 routes present


any help rendered is greatly appreciated!

thanks a lot!

please find forum dedicated to OS specifics.
This problem has NOTHING to do with Oracle RDBMS.
I am locking this thread.
If you disagree, PM or Report Thread stating why it should be unlocked.
