Switching oslo.vmware’s backing SOAP library
With Python 2 being removed from all of OpenStack, we need the library backing oslo.vmware’s SOAP calls to be compatible with Python 3. We see suds-jurko as being unmaintained upstream, so we cannot rely on any changes happening. Since we currently already see deprecation warnings generated by nova’s tests for Python 3.6, we need a fix before the release of Python 3.10 or oslo.vmware will stop working alltogether.
Additionally, the vast number of VMs handled by a single compute-node with nova’s VMware driver makes suds-jurko a performance bottleneck. This can be overcome with switching to a library more optimized for parsing XML.
