Yes. VMware Tools will continue to be available under a commercial license. Partners will continue to have flexibility in deciding between providing commercial or open source implementations of their solutions.
- Does this open-vm-tools relate to other open source virtualization projects?
We are not aware of any other open source projects that currently implement the kind of technology we are releasing. That said, we are always looking for opportunities to collaborate and work with the community to build best in class, open source drivers, applications and utilities that will improve the overall user experience of guest operating systems running in a virtualized environment.
