libvirt users - Apr 2020 - Getting Intel RDT cache allocation status from libvirt?

Is there a way to get the current cache allocation status of a host
from libvirt, via API or virsh?

I've seen some references to a 'virsh nodecachestats' command in
some
patches from 2017 that doesn't seem to exist, and I see that 'virsh
domstats --cpu-total <domain>' has similar information but seems to be
focused on cache monitoring information rather than the allocation
status.

Thanks,
Neil
