Hi folks,
I compiled and installed libvirt latest version 1.2.6, based on this tutorial,
http://blog.scottlowe.org/2012/11/05/compiling-libvirt-1-0-0-on-ubuntu-12-04...
I have compiled qemu and installed too, and make a symbolic link to /usr/bin/qemu-system-x86_64
but my question is even I launch a vm in qemu, $virsh list showed nothing, further more,
1) if I use virtual machine manager, it get connection failiure, due to socket to '/var/run/libvirt/libvirt-sock'; No such file of dirctory.
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?
2). there is missing libvirt-bin under /etc/init.d/, after compile and installed libvirt 1.2.6
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.
Usually, Ubuntu uses upstart. So, there should be a /etc/init/libvirt-bin.conf which defines the libvirt daemon upstart job. I'm not sure whether the configure script detects upstart and installs the upstart files automatically, though.
3). I tried to start libvirtd daemon, sudo /usr/sbin/libvirtd/start shows "/usr/sbin/libvirtd: unexpected, non-option, command line arguments"
I guess that you tried to run "sudo /usr/sbin/libvirtd start"?! This won't work as "/start" is not a valid non-option command line argument as the error message already told you.
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
"sudo start libvirt-bin" is a shortcut method which does the same, BTW. -- Claudio --
