Introduced in v8.2.0-rc0~74^2~2, QEMU now allows setting .dynamic-memslots attribute for virtio-mem-pci devices. When turned on, it allows memory exposed to guest to be split into multiple memslots and thus smaller memory footprint (see the original commit for detailed explanation). Therefore, introduce new <target/> attribute which will control that QEMU knob. Signed-off-by: Michal Privoznik <mprivozn@redhat.com> Reviewed-by: Peter Krempa <pkrempa@redhat.com>
