Hmm, this comes from my old patches. IIRC the reason for the change, when it wasn't a change (many conflicts ago) was that Xen folks were using --disable-tcg because their device model for Xen PV on ARM was actually an x86_64 QEMU. Stefano and Anthony, is this still true? If so, would it make sense to add the Xen PV machine type to qemu-system-arm---that is, is it something you can whip up easily, or should I just remove that line?

I think you should just fix configure for the moment, because this patch wasn't supposed to change anything about what we build (AIUI). We can think about changing the Xen PV on ARM build setup as a separate thing if we want to, I suspect it is more invasive than a couple of lines changing in configure. thanks -- PMM

Yes, definitely more invasive. I'll prepare a fix. Paolo

Let's leave the current build issue aside for a moment, given that it seems to be solved now. Today, we build qemu-system-i386 for Xen on ARM just for the xenpv machine. Using qemu-system-i386 causes all sort of confusion in our users and even distro packagers. Using qemu-system-aarch64 on ARM64 would be better. But the best solution I think it would be to build a cpu-less arch-neutral xenpv machine. Something like qemu-system-null or qemu-system-xen.

In fact, --disable-tcg was the prerequisite for that if I remember correctly my old discussions with Citrix folks (could it have been Wei Liu?)

This will be useful when the functions are called, early in the configure process, to filter out targets that do not support hardware acceleration.
