Thank you for your answer, I know this configuration, but my physical host is reboot, and i want to restart the virtual machine manually instead of by Opennebula. I mean those interfaces are not up when the physical host starts.
I almost know why Opennebula do this, because she want all operations to vm is taken by her not by us.

Opennebula recreates all necessary interfaces on demand.
It means that, once a virtual network uses .1Q, it will create the bridge to route the traffig and map the VLAN on the physical interface.
Dependenig on your distribution, you may need to specify the path of the bridge control binary (brctl).
On Red Hat derivative, it is located on /usr/sbin/brctl; whereas the default location should be /sbin/brctl.
You can either tweak the network scripts to look for the correct path or make a link.

1. First, I create a vm on computer14, i saw network interfaces below:

2. Then, i reboot computer14
[oneadmin at computer14 ~]$ sudo shutdown -r now
3. After this operation，i saw vconfig network interface has gone （eth0.100, onebr100）
[oneadmin at computer14 ~]# ifconfig
eth0 Link encap:Ethernet HWaddr E8:39:35:18:A1:60

4. When I create that vm, error occurred below:
[root at computer14 images]# pwd
/one_images/25/images
[root at computer14 images]# ls
deployment.0 disk.0 disk.1
[root at computer14 images]# virsh create deployment.0
error: Failed to create domain from deployment.0

We've been using 802.1Q under CentOS 6 without problems for quite a long
time.
Can you post a detailed description of what is happening?
Thanks
