Re: [libvirt] [PATCH 0/2] vbox: add support for 5.1.x

Hi Andrea, Sure, in this case those patches simply enable support of VirtualBox 5.1.x series in libvirt (prior to that libvirt supported vbox 2.x.x to 5.0.x)- and as such it does not affect any previous version that libvirt supported.  When upstream VirtualBox releases new version bumping major/minor version tag it is usually coupled with new COM IID strings that are bundled in the SDK which essentially bumps the VBOX API version as well. Adding those SDK headers to livirt, enables it to communicate with the updated VBOX COM interface and avoids "unsupported API version" error message when one does virsh -c vbox:///session with VirtualBox 5.1.x installed on the machine.
