Sorry, let me rephrase the question again:

I need define a user /password for sasl but want the authentication at runtime be automatic - no explicit promting the user while accessing a tcp socket

with some applications that need authentication (e.g libvirt)

I try : saslpasswd2 -c -p -a libvirt <user>

and it hangs (if i now press Enter it says : "invalid parameter supplied") . if I avoid the -p flag the above commad works fine and prompts for password and later when using the tcp (virsh -c qemu+tcp:...) it prompts for the above defined user/password and autheticates ok.

But I want without the explicit authentication

The man pages says : "-p Pipe mode - saslpasswd2 will neither prompt for the password nor verify that it was entered correctly. This is the default when standard

input is not a terminal. "

In the past (before upgrading of libvirt via rpm) I had the SASL authentication done automatically without prompting the user at runtime (virsh qemu+tcp:///system <command> ) and without need to configure that.

Don't know how to restore it .

Any help ?

thanks

I need define a user /password for sasl but want that to do the verification automatically no -promting ( or even maybe avoid the verification) while using a tcp socket with some applications that need authentication (e.g

libvirt)

so I try : saslpasswd2 -c -p -a libvirt <user>

and it hangs (if i now press Enter it says : "invalid parameter supplied") . if I avoid the -p flag the above commad works fine and prompts for password and later when using the tc p (virsh -c qemu+tcp:...) it prompts for the above defined user/password and autheticates ok . But I want without the prompting

The man pages says -p Pipe mode - saslpasswd2 will neither prompt for the password nor verify that it was entered correctly. This is the default when standard input is not a terminal.

I have fedora14 installed with standard libvirt-0.8.3. I can start VM using .xml files and also run: virsh schedinfo. the cgroup CPU controller is mounted and active . In fact I have the path to the Virtual machine : /dev/cgroup/cpu/libvirt/qemu/<vm name >

Now I upgraded to libvirt-0.8.8 from a tar ball ( configure , make , make install) . I rebooted , new libvirtd started . virsh is working ok (I can create a vm) except for the commands : schedinfo and memtune that say upon ' virsh schedinfo <vm name>'

Scheduler : Unknown error: Requested operation is not valid: cgroup CPU controller is not mounted

Indeed I have the path : /dev/cgroup/cpu/libvirt/qemu/ but now without the <vm_name> group which is not generated despite that the VM was generated ok by virsh and I can access it

Any idea what is missing or some config file needs a change ?

thanks
