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.
see commit cd5ff8333a3c87 for detailed info.
Short answer is it's not really resolved [*],
-numa node,mem will keep working on newer QEMU but only for old machine types
new machine types will accept only -numa node,memdev.
One can check if "mem=' is supported by using QAPI query-machines
and checking numa-mem-supported field. That field is flipped to false
for 5.0 and later machine types in this patch.
