Are you able to run 'strace' (or whatever MacOS eqiuv is) to see
the values passed to setgroups when it fails ?
I ran `dtruss -f -l -s /usr/local/sbin/libvirtd` but the setgroups
calls seem to be missing.
Looking at other sources, it seems like some have special treatment of
setgroups on MacOS, e.g. samba:
https://github.com/samba-team/samba/blob/v4-11-stable/source3/smbd/sec_ct...
Perhaps this is needed for libvirt?
