1. First, I create a vm on computer14, i saw network interfaces below:
[oneadmin at computer14 ~]$ ifconfig
eth0 Link encap:Ethernet HWaddr E8:39:35:18:A1:60
inet addr:10.72.24.216 Bcast:10.72.24.255 Mask:255.255.255.0

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
inet addr:10.72.24.216 Bcast:10.72.24.255 Mask:255.255.255.0
inet6 addr: fe80::ea39:35ff:fe18:a160/64 Scope:Link

RX bytes:13317 (13.0 KiB) TX bytes:12829 (12.5 KiB)
Memory:fbe60000-fbe80000
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
error: Failed to add tap interface to bridge 'onebr100': No such device

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
