Abstract: A disclosed method initializes a sideband management (SBM) bridge coupled to a system bus of an information handling system to identify an operating system (OS) domain resource, e.g., a hardware component or an OS resource, as a sideband-manageable resource. An OS-isolated environment, e.g., a virtual machine (VM) or rootless container, may then be associated with the SBM bridge. Thereafter, the OS domain resource may be managed from the OS-isolated environment via the SBM bridge. The system bus may be a peripheral component interconnect express (PCIe) bus and the SBM bridge may be a PCIe bridge. The SBM bridge may include a single root I/O virtualization (SR-IOV) interface and initializing the SBM bridge may include initializing, by the OS domain resource, a physical function (PF) of the SBM bridge. In such embodiments, associating the OS-isolated object with the SBM bridge may include assigning a virtual function (VF) of the SBM bridge to the OS-isolated object.
