Thank you Eric. Yes, it looks like AppArmor caused the problem. I will google on how to disable it. On 8/5/14 8:27 PM, "Eric Blake" <eblake@redhat.com> wrote:

It seems something related to selinux. However, my box seems not have selinux installed at all.
It's probably AppArmor, not SELinux; but the concepts are the same - if you have a mandatory access control that libvirt can use, then you have to make sure that non-default locations are permitted through your control mechanism, in order for libvirt sVirt protections to work with your layout.
Anyone knows how to fix this?
Sadly, I don't use AppArmor myself to offer actual advice on it.
