Molto probabilmente avete eseguito il riavvio del vostro host in un kernel, il quale non risulta essere un kernel
xen-hypervisor . Per correggere questo problema è necessario selezionare il kernel xen-hypervisor al momento dell'avvio (oppure impostare il kernel xen-hypervisor ), come default all'interno del vostro file grub.conf .
