Comment 50 for bug 799997

Still occurs on Ubuntu 14.04 using libvirt 1.2.2 .

Here are my reproduction steps.

Try with " " in <name>:

    $ tar -xvf my-vm.tar.gz
    my-vm/
    my-vm/my-vm-data.qcow2.md5
    my-vm/my-vm.xml

    $ cd my-vm/

    # <name> has space
    $ grep -Fe '<name>' -- my-vm.xml
      <name>My VM</name>

    $ sudo virsh define my-vm.xml
    Domain My VM defined from my-vm.xml

    # BUG: fails to start
    $ sudo virsh start "My VM"
    error: Failed to start domain My VM
    error: internal error: cannot load AppArmor profile 'libvirt-1a2ef3c1-a758-40f6-a238-c84ef3e8c9d6'

Remove bad KVM:

    $ sudo virsh undefine "My VM"
    Domain My VM has been undefined

Try again without " ", use "-":

    $ vim my-vm.xml

    # <name> without spaces
    $ grep -Fe '<name>' -- my-vm.xml
      <name>My-VM</name>

    $ sudo virsh define my-vm.xml
    Domain My-VM defined from my-vm.xml

    # starts
    $ sudo virsh start "My-VM"

Using software versions

    $ sudo dpkg -l | grep libvirt
    ii libvirt-bin 1.2.2-0ubuntu13.1.16 amd64 programs for the libvirt library
    ii libvirt0 1.2.2-0ubuntu13.1.16 amd64 library for interfacing with different virtualization systems
    ii python-libvirt 1.2.2-0ubuntu2 amd64 libvirt Python bindings
