Avocado-vt dependencies don't work

[ghost]

I've tried to reproduce the example in http://avocado-vt.readthedocs.org/en/latest/advanced/VirtTestDocumentation.html#dependencies, with no success.
My complete .cfg file:

- hostname:
    type = network/hostname
    virt_test_type = qemu libvirtlibvirt
    get_hostname_command = hostname
    variants:
        - two: one
            key2 = World
        - three: two
        - one:
            key1 = Hello

Avocado output:
(1/3) ibm-kvm-bvt.hostname.two: ERROR (4.15 s)
(2/3) ibm-kvm-bvt.hostname.three: PASS (4.30 s)
(3/3) ibm-kvm-bvt.hostname.one: PASS (4.37 s)

As you can see, the tests are run out of desired order (they appear to always run in the written order) and they run even when dependencies fail.

The dep param of the test "two" contains:
dep = ['libvirt_quick.qemu.bridge.default_bios.no_virtio_rng.(image_backend=filesystem).no_9p_export.smallpages.no_pci_assignable.qcow2.virtio_blk.s
mp2.virtio_net.Linux.PowerKVM.olavph-1206.ppc64le.install.pseries.(subtest=ibm-kvm-bvt).(subtest=hostname).one']
