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

(virsh qemu+tcp:///system <command> ) and without need to configure

Don't know how to restore it .

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

machine : /dev/cgroup/cpu/libvirt/qemu/<vm name > Now I upgraded to libvirt-0.8.8 from a tar ball ( configure , make ,

install) . I rebooted , new libvirtd started . virsh is working ok (I can create a vm) except for the commands : schedinfo and memtune

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

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 Zvi Dubitzky Email:dubi@il.ibm.com ------------------------------ _______________________________________________ libvirt-users mailing list libvirt-users(a)redhat.com https://www.redhat.com/mailman/listinfo/libvirt-users End of libvirt-users Digest, Vol 15, Issue 26 *********************************************
