Pkrempa help me find a root reason, I have two instances of the library on my host now: # nm -A -D /usr/lib64/libvirt.so.0.10.1 | grep "LIBVIRT_0.10." /usr/lib64/libvirt.so.0.10.1:0000000000000000 A LIBVIRT_0.10.0 # nm -A -D /usr/lib/libvirt.so.0.10.1 | grep "LIBVIRT_0.10." /usr/lib/libvirt.so.0.10.1:0000000000000000 A LIBVIRT_0.10.0 /usr/lib/libvirt.so.0.10.1:0000000000000000 A LIBVIRT_0.10.2 It's not enough to run ./configure with --prefix=/usr, also should append --libdir=/usr/lib64 or use ./autogen --system, a weird question is ./configure --prefix=/usr worked well for me ago.
