However, while starting libvirtd, there is still an error here: Sorry I forgot the command line I used to start the libvirt service, here

Starting libvirtd daemon: libvirtd: /usr/lib64/libvirt.so.0: version `LIBVIRT_PRIVATE_0.9.4' not found (required by libvirtd) libvirtd: /usr/lib64/libvirt.so.0: version `LIBVIRT_PRIVATE_0.9.4' not found (required by /usr/lib64/libvirt-qemu.so.0) [FAILED] Does it mean I cannot remove all of the libvirt binary by only running "make uninstall"? Are there any other ways can be used to remove the libvirt environment completely?
