You will need to add "xen" to your DISTRO_FEATURES to toggle on the yocto kernel config fragment for xen support, as well as libvirt. > 2) What target do I build/bb file do I build. > > I usually build either: > bitbake core-image-minimal ==> Standard Linux for our HW board > bitbake core-image-XXX--XXX ==> Standard Linux for our HW board + additional > application layers. > > I am however unable to understand the connection between the images I > currently build and the Xen-hypervisor, for example: > recipes-extended/libvirt/libvirt_1.2.19.bb:# xen-minimal config > recipes-extended/images/kvm-image-minimal.bb:DESCRIPTION = "A minimal kvm > image" > recipes-extended/images/xen-image-minimal.bb:DESCRIPTION = "A minimal xen > image" > What are above bitbake recipes, should I build xen-image-minimal.bb instead > of core-image-minimal or.... > This largely depends on what you are trying to do, your BSP, if you are using the yocto kernel, etc.. Building xen-image-minimal should provide a bootable dom0 out of the box (at least for typical x86-64) that can start/stop VMs using xl toolstack (not libvirt). Adding xen support is largely about getting the appropriate kernel bits enabled (meta-virtualization provides a config fragment). For dom0, you will also need to configure your bootloader to boot xen, and then you will need to add the packages you desire (qemu, libvirt, xen-base, etc.) to your specific image. Good luck! -- _______________________________________________ yocto mailing list yocto@yoctoproject.org https://lists.yoctoproject.org/listinfo/yocto
