Title:
  vmware driver does not validate server certificates

Status in Cinder:
  Confirmed
Status in OpenStack Compute (Nova):
  Confirmed
Status in Oslo VMware library for OpenStack projects:
  Fix Released

Bug description:
  The VMware driver establishes connections to vCenter over HTTPS, yet
  the vCenter server certificate is not verified as part of the
  connection process.  I know this because my vCenter server is using a
  self-signed certificate which always fails certification verification.
  As a result, someone could use a man-in-the-middle attack to spoof the
  vcenter host to nova.

  The vmware driver has a dependency on Suds, which I believe also does
  not validate certificates because hartsock and I noticed it uses
  urllib.

  For reference, here is a link on secure connections in OpenStack:
  https://wiki.openstack.org/wiki/SecureClientConnections

  Assuming Suds is fixed to provide an option for certificate
  verification, next step would be to modify the vmware driver to
  provide an option to override invalid certificates (such as self-
  signed).  In other parts of OpenStack, there are options to bypass the
  certificate check with a "insecure" option set, or you could put the
  server's certificate in the CA store.
