Presumably you're not proposing that qemu-devel completely ignore the
typical requirements of management apps?
We propose to allow both qemu-allocated slots and user-allocated slots,
so we're only ignoring the actual decision by the management tool
providers, not their requirements.
You can push the discussion to libvirt-devel, and the conclusion would
most likely be:
"We can do slot allocation if you provide us with a way to query free
slots, or we can use qemu's default allocation if you provide us a
way to query the allocation.
We'd prefer the default allocation problem, but we don't really
care. Both require about the same amount of work for us."
Well, they'll find out if they try default allocation. It's
traditional to try all the complicated solutions before trying the
simplest one, so I guess we'll just have to let them.
libvirt was only mentioned in this thread as a concrete example of how
the suggested solutions would actually be used by management apps.
True, others will wind up doing things differently. In fact, I'm a
little surprised that libvirt is involved, since the place to do
inventory is in the management app itself (it's true that libvirt also
maintains its own database, so the line is blurred).

I have a truly marvellous patch that fixes the bug which this
