On amd64, it has XEN option available which adds Xen support through libxl. However, it's not enabled by default (therefore if you're installing libvirt from an official repo, it won't be enabled), so you'll have to build your own version with this option enabled. IIRC, virt-manager supports Xen by default and does not need any additional configuration. > > > -- > > > / . Eric A.
