libvirt users - Sep 2014 - Re: How to configure the container's NIC automatically with an assigned IP address

Dear Gene,

Thank you for your response.

I want to assign a static IP address to my container, I wonder if I can achieve
this by editing the container's /etc/sysconfig/network-scripts/ifcfg-eth0. I
tried this, but failed, and eth0 is always not assigned an IP address
automatically (my host and guest are fedora19).

Am I missing something? I don't know much about the booting procedure of a
container, and how the network NIC is configured during the booting.

The content of container's /etc/sysconfig/network-scripts/ifcfg-eth0 is as
follows:

BOOTPROTO="static"

DEVICE="eth0"

TYPE="Ethernet"

ONBOOT="yes"

IPADDR=192.168.128.15

PREFIX=24

GATEWAY=192.168.128.254



With my warmest regards,

Cheng

Take a look at: http://sandbox.libvirt.org/networking/



Note: Specifying dhcp does not currently work.  I have created a patch to fix
that.  See:
