Correspond to 'x-scalable-mode' and 'x-flts' properties in QEMU.
The 'x-' prefix on these property names indicates QEMU considers them experimental / unstable, which makes them unsuitable for exposing from libvirt. We need the QEMU implementation to become fully supported first.
I see, thanks. I didn't know this rule before. CCing qemu vtd maintainer/reviewers and qemu-devel: Do you think we can drop 'x-' as we had "x-scalable-mode" more than 5 years and "x-flts" more than 1 year? Thanks Zhenzhong
