note that the '-Dsystem=true' argument is supposed to be used with
'meson' as it sets up configure time options. This way it probably did
nothing.
Noted, thanks!

So the directory really looks like libvirtd/virtqemud or any other of
the libvirt daemons never ran.
How did you start the daemons, did they log something?
So, what I did this time was:
$ ninja -C build clean
$ meson build --reconfigure --prefix=$HOME/usr -Dsystem=true
$ ninja -C build
$ sudo ninja -C build install
$ systemctl stop libvirtd
$ systemctl start libvirtd
but I still get:
$ virt-install --name ubuntu-sev --boot

Generally the most straightforward way is to build distribution packages
from the tree and install them directly in your system because then you
avoid issues such as possibly having two libvirtd instances running and
such.
Does libvirt have any script or tool to ease such process?
Thanks in advance,
