Red Hat Virtual Box: Network is unreachable
Solution 1
Thanks to Jaroslav Kucera who said that I should assign an ip to eth0.
I followed this article
I modified /etc/sysconfig/network and /etc/sysconfig/network-scripts/ifcfg-eth0 for DHCP then reboot.
Now I can ping internet.

An additional contribution after chasing the very same complaint for two days: I learned to look for the work " UP " in the NIC line and the br0 line (if present, as they are with virtual machines). I use routinely for both CentOS 7 and RHEL 7 the commands:
# ip link set br0 down
# ip link set br0 up
# systemctl reboot
Verify the primary NICs have an " UP " status as well. They usually do.

Had similar issue
Check that you have following added to:
/etc/sysconfig/network
:
NETWORKING=yes
HOSTNAME=my-hostname
Make sure you have configuration file in respective place (according to your device name):
/etc/sysconfig/network-scripts/ifcfg-enp0s3
in my case:
NAME=enp0s3
DEVICE=enp0s3
ONBOOT=yes
Then run:
ifup enp0s3
(your device name can be different, for example eth0
, so double check that)
Also this command sudo service networking restart
might help in some cases.

I installed a RHEL virtual machine with Virtual Box and I can't ping my host computer nor internet.
I configured 2 adapters:
- Attached to NAT, promiscuous allow all and cable connected
- Atteched to Bridged Adapter, promiscuous allow all and cable connected
When I run
ip addr show
, here is the output:Thank you.

Jaroslav Kucera about 6 yearsFirst of all, the eth0 has no IP address. So either it receives it from VirtualBox or you should assign it with some of the NAT IP segment (probably 192.168.x.x - you should be able to find it in virtualbox somewhere). The eth1 has no connection (virtual wire) as it says it has
NO-CARRIER
and is not inLOWER_UP
state. -
elpha01 about 6 yearsThank you for your clarifications. Can I assign an ip adress to eth0?

Jaroslav Kucera about 6 yearsYes, from proper IP segment.
