actually it seems like a rally bug to me.

after the change Ic8a25eb1a7119a610c255ffa5ce80a8efcd27a0e ,
rally rally-gate.sh creates a VM with admin tenant.
with devstack-created topology, it ends up with booting a VM on public network.
i think it isn't the intended behaviour.

in case of networking-midonet, there are two admin networks (devstack-created
public network and midonet "uplink" network) and ends up with the "Multiple possible networks"
error.

commit 633d0ff464553882143e6432f3c7423c0b75b407

    Revert "Gate: prepopulate cluster with one server"

    This reverts commit 994ed06f64577fd1e719852047b72f95600561e5
    (and its follow-up, b861c0cd4259deac7a0d371436006d78957ec47c)
    because it broke gate-networking-midonet-v2-rally-dsvm-nv job.

    In midonet, typically admin tenant has two networks,
    the usual "public" and midonet-specific "uplink".
    booting a VM without specifying a network fails with
    "Multiple possible networks" error there.

    The reasoning of the original commit is rather unclear to me,
    as listing security groups is enough to populate the default
    security groups for the tenant.

    Closes-Bug: #1589876
