Some general comments on using the patch:
* For libguestfs I chose to add
-compat deprecated-input=reject,deprecated-output=hide
This is only enabled in developer builds of libguestfs when we
are running qemu directly (not via libvirt). The patch for
this is attached.
* What's the point/difference in having reject vs crash?
I'll be adding the following documentation for the qemu.conf entry in
libvirt controling the feature:
+# The "reject" option is less harsh towards the VMs but some code paths ignore
+# errors reported by qemu and thus it may not be obvious that a deprecated
+# command/field was used, thus it's suggested to use the "crash" option
instead.
