Xen VM não pôde ser instalado

Question

Eu aluguei um servidor da Hetzner. Eu instalei o Xen no Dom 0 - Centos 6.5. Não consegui criar uma VM Dom1 Centos 6.5.

O erro que vejo é 'Não é possível recuperar' o link da imagem centos 'ao tentar instalar uma VM Dom1 Centos 6.5.

No Dom 0:

[root@static network-scripts]# cat ifcfg-xenbr0

No Dom 1 durante a instalação do 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])

Alguém por favor pode me ajudar a instalar o Dom1 nesta máquina? Obrigado!
