I'm afraid nobody bothered to fix it yet:

https://bugzilla.redhat.com/show_bug.cgi?id=1783355

It's time to start working on it :)
(looks like just deprecating stuff isn't sufficient motivation,
maybe actual switch flipping would work out better)


So how was the upgrade from older to newer version resolved? I mean, if the old qemu used -numa node,mem=XXX and it is migrated to a host with newer qemu, the cmd line can't be switched to -numa node,memdev=node0, can it? I'm asking because I've just started working on this.
