Hello,
I am trying to test some changes made to libvirt. I tried compiling and
installing, following the available documentation, with:
ninja -C build clean
meson build --prefix=$HOME/usr
ninja -C build -Dsystem=true
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!
sudo ninja -C build install
After doing this, I try to run virt-install and get the following error on
the active libvirtd daemon:
Failed to connect socket to '/var/local/run/libvirt/virtqemud-sock': No
such file or directory
Indeed, that file does not exist:
$ ls /var/local/run/libvirt/
common hostdevmgr lockd lxc network nwfilter nwfilter-binding secrets
storage
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 was working fine before started changing libvirt's source code.
I'm working with Ubuntu 22.04 LTS, virsh v8.7.0.
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,
Carlos
