Before running "virsh create", the image belongs to user oneadmin. During the run, it still does.

CGroups are not something that is turned off at compile time, they will always be present. This message simply means that you do not have the cgroups controllers mounted on this host, so libvirt has disabled that functionality at runtime. This means you won't be able to use any of the schedular APIs with QEMU guests. Aside from that it is harmless, so either ignore it, or setup cgroups as best suis you Daniel -- |: Red Hat, Engineering, London -o- http://people.redhat.com/berrange/ :| |: http://libvirt.org -o- http://virt-manager.org -o- http://ovirt.org :| |: http://autobuild.org -o- http://search.cpan.org/~danberr/ :| |: GnuPG: 7D3B9505 -o- F3C9 553F A1DA 4AC2 5648 23C1 B3DF F742 7D3B 9505 :| -- Libvir-list mailing list Libvir-list@xxxxxxxxxx https://www.redhat.com/mailman/listinfo/libvir-list
