Leaked resources after cold migration

[Alexandru Muresan]

At the moment, the vif ports are not unplugged after cold migration on the source node.

This affects ovs ports, which have to be unplugged by nova.

At the same time, attached volumes are not disconnected from the source node.

    Disconnect volumes after cold migrations

    After cold migrating an instance, volumes are not disconnected on
    the source node side. This change fixes it.

    A recent change fixed a similar issue regarding vif ports but we've
    missed volume connections.

    Hyper-V: Perform proper cleanup after cold migration

    At the moment, vif ports and volume connections are not cleaned up
    on the source node after a cold migration.

    This change addresses this issue by passing the network and block
