Yes.

The above "PREFERRED" settings doesn't capture QMP commands, does it?
The '1:qemu' is supposed to do it.
It has 1:* since after 4 it supports wildcats which is equivalent to
1:qemu.
FWIW, after some debugging sessions with Dan Berrangé, I have been
using
the following filters:
"1:libvirt 1:qemu 1:conf 1:security 3:event 3:json 3:file 3:object 1:util"
Didn't you debug a 4.4.0 or older libvirt?
Should the document be updated with the above filters? (Assuming this
set looks good to the reviewers.)
