Open Stack

Hi all,

I had created a redhat image by using kvm-img in qcow2 format. And it is
uploaded to the openstack successfully.

But when I lanuch a instance and access it over the vnc, the network(in
default, just the eth0 device is up on boot) is not startup. I check the
the vm by using ip link and got following output

1: lo: <LOOPBACK,UP,LOWER_UP> mtu 16436 qdisc noqueue state UNKNOWN
    link/loopback 00:00:00:00:00:00 brd 00:00:00:00:00:00
2: eth1: <BROADCAST,MULTICAST,UP,LOWER_UP> mtu 1500 qdisc pfifo_fast
state UP qlen 1000
    link/ether fa:16:3e:78:44:10 brd ff:ff:ff:ff:ff:ff

It seems that the network bind itself to the second device. I want to know
why it happeded and how to fix this?

here is other config file

*/etc/sysconfig/network-scripts/ifcfg-eth0 in the Vm*

DEVICE="eth0"
BOOTPROTO="dhcp"
#HWADDR="52:54:00:12:34:56"
#NM_CONTROLLED="yes"
ONBOOT="yes"
TYPE="Ethernet"
#UUID="e11caf36-bc22-48ee-8dbe-321043da29a5"

*there is not /etc/sysconfig/network-scripts/ifcfg-eth1 file*

*the libvirt.xml for the vm*

<domain type="kvm">
