NSX-mh: Decimal RXTX factor not honoured

Bug #1463363 reported by Salvatore Orlando on 2015-06-09
This bug affects 2 people
Affects Status Importance Assigned to Milestone

Bug Description

A decimal RXTX factor, which is allowed by nova flavors, is not honoured by the NSX-mh plugin, but simply truncated to integer.

To reproduce:

* Create a neutron queue
* Create a neutron net / subnet using the queue
* Create a new flavor which uses an RXTX factor other than an integer value
* Boot a VM on the net above using the flavor
* View the NSX queue for the VM's VIF -- notice it does not have the RXTX factor applied correctly (for instance if it's 1.2 it does not multiply it at all, if it's 3.4 it applies a RXTX factor of 3)

    Remove duplicated call to setup_coreplugin

    The test case for vlan_transparent was calling setup_coreplugin
    before calling the super setUp method which already calls
    setup_coreplugin. This was causing duplicate core plugin fixtures
    which resulted in patching the dhcp periodic check twice.

    Remove double mock of dhcp agent periodic check

    The test case for the periodic check was patching a target
    that the core plugin fixture already patched out. This removes
    that and exposes the mock from the fixture so the test case
    can reference it.

    Remove ensure_dirs double-patch

    test_spawn_radvd called mock.patch on ensure_dirs after the
    setup method already patched it out. This causes issues when
    mock.patch.stopall() is called because the mocks are stored
    as a set and are unwound in a non-deterministic fashion.[1]
    So some of the time they will be undone correctly, but others
    will leave a monkey-patched in mock, causing the ensure_dir
    test to fail.

    Remove failing SafeFixture tests

    The fixtures 1.3 release attempted to fix the fixtures resource
    leak issue, but failed to do so completely. Our own SafeFixture
    is still needed: The 1.3 release broke our SafeFixture tests,
    but not the usage of SafeFixture itself. This patch removes
    those failing tests for now to unbreak the gate. Jakub reported
    a bug on fixtures 1.3:

    We will continue to use SafeFixture until that bug is fixed
    in fixtures, at which point we will be able to require
    fixtures > 1.3.

    Revert "Removed test_lib module"

    This reverts commit 9a6536de6e1a7fe9b2552adc142e254426b82b6f.

    We pulled all of the plugins out of the tree, many of which still inherit
    from neutron test classes. This change then stated that we no longer
    support testing other plugins. I think this is a bit premature and should
    have been discussed under the subject
    "Neutron plugins can't use neutron plugin unit tests" or something

    Refactor NetcatTester class

    Following capabilities were added:
       - used transport protocol is passed as a constant instead of bool
       - src port for testing was added
       - connection can be established explicitly
       - change constructor parameters of NetcatTester

    As a part of removing bool for protocol definition
    get_free_namespace_port() was also modified to match the behavior.

    NSX QoS ext: RXTX factor can be decimal

    In Nova flavors it is ok to specify a decimal RXTX factor.
    For this reason when applying QoS to a port Neutron should not
    convert this factor to an integer value, but simply ensure
    it's a valid float number and positive.

    Do not convert RXTX factor to int

    Decimal RXTX factors are allowed in nova flavours and
    should be supported by the MH plugin as well.
    This patch drops the conversion to integer but still ensures
    that the resulting maximum bandwidth after applying the RXTX
    factor is still an integer value.
