Boa noite caros,Estou migrando o servidor e queria testar o Xen no Centos. Hoje em dia o Xen é rodado no Debian 7, tanto o hospedeiro, como as as VMs.
A situação atual é o seguinte, quero migrar as VMs Debian para o Centos. Fiz todas as confs, o Domain-0 tá online, desabilitei o SElinux no hospedeiro, entretanto quando inicio a VM me aparece o seguinte erro(cópia da tela):
