Re: [libvirt] [PATCHv2] python: Fix emulatorpin API bindings

The addition of emulator pinning APIs didn't think of doing the right job with python APIs for them. The default generator produced unusable code for this. This patch switches to proper code as in the case of domain Vcpu pining. This change can be classified as a python API-breaker but in the state the code was before I doubt anyone was able to use it successfully. --- python/generator.py | 2 + python/libvirt-override-api.xml | 18 +++++- python/libvirt-override.c | 118 ++++++++++++++++++++++++++++++++++++++++ 3 files changed, 136 insertions(+), 2 deletions(-)
