I have rented a server from Hetzner. I have installed Xen on Dom 0 - Centos 6.5. I couldn't create a Dom1 Centos 6.5 VM.
The Error I see is 'Unable to retrieve 'the link for centos image' while trying to install a Dom1 Centos 6.5 VM.
On Dom 0 :

On Dom 1 while installing Centos 6.5 :
I selected Manual IPV4 :
IP ADDR : 5.9.*.*
Subnet : *
Name server : Same as DNS1 in Dom0.
Gateway : I used IP of host to be the gateway for Dom 1 (I followed [this tutorial][1])
Can someone please help me to get the Dom1 installed on this machine? Thanks!
