If you run `apt install virt-manager` it will install virt-manager, libvirt, qemu and everything needed to run and use the software. If you run `apt build-dep libvirt` it will install everything needed to compile libvirt but not necessarily everything you need to actually run it. If you do only build-dep for libvirt you will have no virt-manager and you would not be able to use it. You would have only libvirt. > On Thu, Aug 24, 2023 at 3:16 PM Pavel Hrdina <<a href="mailto:phrdina@redhat.com" target="_blank">phrdina@redhat.com</a>> wrote: > > > On Wed, Aug 23, 2023 at 08:47:55PM +0200, Mario Marietto wrote: > > > I've fixed this problem : > > > > > > virsh: /lib/arm-linux-gnueabihf/libvirt.so.0: version > > > `LIBVIRT_PRIVATE_9.0.0' not found (required by virsh) > > > > > > now,virsh works if I launch it within the build directory of libvirt : > > > > > > root@devuan:~/libvirt_build/bin# ./virsh > > > Welcome to virsh, the virtualization interactive terminal. > > > > > > Type: 'help' for help with commands > > > 'quit' to quit > > > > > > but inside the build directory of libvirt I don't see any virt-manager > > > executable,so I'm forced to run it like this : > > > > > > root@devuan:~/Desktop/libvirt/build# ./run /usr/bin/virt-manager > > > > > > and it gives the previous error : no connection driver available for > > > qemu:///system > > > > > > but the fact that virsh works is a progress ? should I compile > > virt-manager > > > also from source code ? > > > > No, there is no need to compile virt-manager, it is written in python > > and so there is no compilation involved at all. > > > > > > I would probably recommend you to remove `~/libvirt_build/` and > > `~/Desktop/libvirt/build/` directories and start again. > > > > If you've successfully installed all libvirt build dependencies using > > `apt build-dep libvirt` you should have everything to build your own > > libvirt if you are on Devuan 5. > > > > The next step would be configuring libvirt so you can compile it using > > the following command executed in the libvirt source directory: > > > > meson setup build > > > > Once that is completed you can build and install your libvirt using > > the following command directly from the source directory as well: > > > > ninja -C build > > sudo ninja -C build install > > > > The first one will build libvirt (I would not run it as root) and the > > second one will install it into /usr/local/. > > > > After that is done you should be able to run virsh and libvirtd directly > > without any run script.
