Xen erro ao cria o dominio

Estou tenatndo criar um dominio no xen e esta apresentando este e

#xm create /etc/xen/vm/vm3
Using config file "/etc/xen/vm/vm3".
Error: Not an HVM capable platform, we stop creating!

Alguem tem algum ideia ???

voce está tentando instalar um domU que necessita de HVM (hardware virtualization)? poste o arquivo de configuracao e nos diga em que máquina está instalando, e em que versão do xen, por favor

Olha, eu achei uma penca de resultados no Google sobre o seu problema. Dá uma olhada:

# "destroy", meaning that the domain is cleaned up as normal;
# "restart", meaning that a new domain is started in place of the old
# one;
# "preserve", meaning that no clean-up is done until the domain is
# manually destroyed (using xm destroy, for example); or
# "rename-restart", meaning that the old domain is not cleaned up, but is
# renamed and a new domain started in its place.

Descobri que meu processador não tem suporte a vt.
Alguem sabe se existe alguma outra opção de usar xen,
colocando no arquivo de configuração parmetro builder difrente de hvm.
