I got your point, thanks a lot! 

I think the self-build libvirt didn't start, but there is no libvirt-bin under /etc/init.d/, don't know how to start it, and  $ initctl start libvirt-bin    shows unknow job: libvirt-bin.

I remember compile and installed libvirt before, but don't remember the parameters passed when configure it, just make uninstall, make clean before this newly installation.


Thanks a lot!

Best,
Yuanzhen

That's not the actual error message (because the actual message wouldn't
mis-spell directory), but is generally the message you see when libvirtd
is not running.  Are you sure you got your self-built libvirtd installed
and running correctly?

I'm not familiar enough with libvirt on ubuntu to know if this is a
problem.  If you are going to replace your distro's old libvirt with a
newer self-built version, it is STILL helpful to install your distro's
libvirt first, to make sure that all the distro-specific tweaks (such as
setting up /etc/init.d/ and so forth to run libvirtd as a daemon) are in
place.

According to the tutorial blog that you linked to, it seems like you
would use 'sudo initctl start libvirt-bin' and not 'sudo
/usr/sbin/libvirtd/start' to start libvirtd - but again, I'm not enough
of an ubuntu user to verify this myself.  Again, until you are sure that
your ./configure arguments matched the distro build, and that you have
got libvirtd running correctly, then the rest of your symptoms are
evidence that you didn't install your replacement self-built libvirt
correctly for what the rest of your distro is expecting.
