Hi Daniel,
What version of QEMU do you have installed ? Libvirt has recently become more aggressive at requiring modern QEMU versions, so its possible if your old libvirt was running against old QEMU, that might not be supported with new libvirt.
I'm using QEMU 2.8 here. That might explain why libvirt cannot find a version that is modern enough. In the meantime I tried to build an older version of libvirt: 4.0.0, to see if it would work, but i can't start the daemon: $ sudo ./libvirtd ./libvirtd: /var/ansible/usr/lib/libvirt-admin.so.0: version `LIBVIRT_ADMIN_PRIVATE_4.0.0' not found (required by ./libvirtd) ./libvirtd: /var/ansible/usr/lib/libvirt.so.0: version `LIBVIRT_PRIVATE_4.0.0' not found (required by ./libvirtd) What is it complaining about ? I used the same configuration as above: ./configure --prefix=$HOME/usr --localstatedir=/var Thanks. -- Mathieu Tarral
