Created virtual network may conflict with existing networks

[GarySmith]

When mkcloud creates the virtual networks in libvirt, it should first check that it is not creating a network that overlaps with any existing virtual network that may be present. Failure to make this pre-check may cause network requests fail in ways that may be difficult to diagnose, especially when there is only a partial overlap, i.e. requests to/from some interfaces work properly and others do not.

precreated in libvirt you mean? or created outside libvirt?

[GarySmith]

Yes, pre-created in libvirt.
