Hey Naichuan, FWIW, we discussed on the missing pieces for nested resource providers. See the (currently-in-use) etherpad https://etherpad.openstack.org/p/nova-ptg-stein and lookup for "closing the gap on nested resource providers" (L144 while I speak)
The fact that we are not able to schedule yet is a critical piece that we said we're going to work on it as soon as we can. -Sylvain On Thu, Sep 13, 2018 at 9:14 AM, Eric Fried <openst...@fried.cc> wrote: > There's a patch series in progress for this: > > https://review.openstack.org/#/q/topic:use-nested-allocation-candidates > > It needs some TLC.
