Contributed to the xcp-ng-org repository by updating PCI Passthrough documentation for XCP-ng 8.3, focusing on clarifying technical prerequisites and new hardware support. The work involved revising Markdown-based documentation to specify that SR-IOV is no longer required for PCI Passthrough and that USB controllers can be passed through when the RMRR policy is enabled, reflecting recent silent changes in Xen and XAPI. This update aimed to reduce ambiguity for both users and support teams during deployment. The contribution demonstrated attention to detail in technical writing and a strong understanding of virtualization concepts and documentation best practices.
