This commit is based on the previous work available from https://github.com/libvmi/bareflank_libvmi_extension which targeted the base Bareflank hypervisor without Boxy. With Boxy we gain guest support which allows us to run LibVMI inside a tiny Linux VM and by the same token allows us to target a Windows host, which was otherwise not possible before. 3 hypercalls are currently implemented: - v2p to translate a GVA to GPA - map_pa to map a page at GPA using EPT - get_registers (only implements a subset for now) It currently only works with Linux as Windows produces BSoD of random error types and will need to be fixed.

@chp-io If needed BTW, since you have a lot of PRs that are coming, please feel free to address these issues in future PRs. So long as we can agree on the changes... I am fine with merging this now, knowing that they will be addressed in future PRs |

This PR is outdated. In a new PR I will include the new MicroV implementation used by LibVMI. |
