I have checked that I removed all distro things, ran self-built virsh, libvirtd. To make sure, I use absolute paths for running. Also I will check process status in time. This is "ps" shown:2996 1 3 08:48 ? 00:00:00 /usr/local/libvirt/sbin/libvirtd -d
Is there some thing wrong? I can't search "libvirt-sock" after runing it.
