I am using CentOS 6.5 64
and use xen to create a virtual machine (CentOS)

First of all if you are using VirtualBox to host the XEN server please ensure to use Ethernet not Wireless network and set Promiscuous Mode to "Allow All".
Secondly just to make everything clean, let's start with clean installation of CentOS with XEN and install the Bridge Network and CentOS VM on it.
Assuming you have external server 192.168.1.6 with CentOS ISO extracted on /var/www/html/centos/6.3/os/i386/ and kickstart file on /var/www/html/centos/6.3/os/i386/ks.cfg and /var/www/html/centos/6.3/os/i386/repodata with correct names match names in repodata/TRANS.TBL file
On the XEN server (CentOS+XEN) install the following packages:
Then edit ifcfg-* file to create the bridge
edit
HWADDR=XX:XX:XX:XX:XX:XXline to match your MAC address. Don't reboot on ssh console, use VBox consoleafter reboot, assuming you have DHCP server the XEN server will got a new IP, login via VBox console to get the new IP
ifconfig result should be similar to
Now the bridge is ready you can use the IP of br0 to get ssh console again
To create a virtual machine on XEN which use previous bridge:
Create virtual disk:
Then use virt-install to create the VM:
Now the VM should start and be able to get IP from the DHCP server normally and able to complete unattended remote installation.
The ifconfig result on XEN should be similar to:
After the installation complete you can use xen console to get the IP of it, then you can have ssh console on it.
