[one-users] Permission libvirt/qemu driver

[Guillaume GENS]

hi

I've got a problem deployment about ttylinux image in my Opennebula
infrastruture (self-contained installation). I think It's a permission
problem between libvirt and his qemu driver, I tried many solution but
i can't resolve it.

in /srv/cloud/one/var/14/vm.log:
