Currently non-x86 guests must have <acpi/> defined in <features> to prevent libvirt from running qemu with -no-acpi. Although it works, it is a hack. Instead add a capability flag which indicates whether qemu understands the -no-acpi option. Use it to control whether libvirt emits -no-acpi. Current versions of qemu always display -no-acpi in their help output, so this patch has no effect. However the development version of qemu has been modified such that -no-acpi is only displayed when it is actually supported. Signed-off-by: Michael Ellerman <michael@ellerman.id.au>
LibVirt : simple API for virtualization Libvirt is a C toolkit to interact with the virtualization capabilities of recent versions of Linux (and other OSes). It is free software available under the GNU Lesser General Public License. Virtualization of the Linux Operating System means the ability to run multiple instances of Operating Systems concurrently on a single hardware system where the basic resources are driven by a Linux instance. The library aim at providing long term stable C API initially for the Xen paravirtualization but should be able to integrate other virtualization mechanisms if needed.

virtualization technologies provided by many operating systems. It
includes support for QEMU, KVM, Xen, LXC, bhyve, Virtuozzo, VMware
