Techniques to facilitate out of band management in a virtualization environment

A method comprising:

• receiving, at a management controller for a computing platform, domain information for a domain for use by software or a device driver executed by a virtual machine (VM), the domain information indicating that the domain is mapped to physical memory addresses of one or more storage devices coupled with the computing platform via which the software or the device driver is able to directly access, manage or control at least a portion of the one or more storage devices;
• assigning a multiple component transport protocol (MCTP) endpoint identifier (EID) to the domain;
• receiving a request message from a management entity for a data center that includes the computing platform, the request message received via an out-of-band (OOB) communication link and including information directed to the software or the device driver;
• and
• forwarding the request message in one or more MCTP packets that indicate the assigned MCTP EID is a destination MCTP endpoint for the request message.

At least one machine readable medium comprising a plurality of instructions that in response to being executed by a system at a management controller for a computing platform, cause the system to:

• receive domain information for a domain for use by software or a device driver executed by a virtual machine (VM), the domain information indicating that the domain is mapped to physical memory addresses of one or more storage devices coupled with the computing platform via which the software or the device driver is able to directly access, manage or control at least a portion of the one or more storage devices;
• assign a multiple component transport protocol (MCTP) endpoint identifier (EID) to the domain;
• receive a request message from a management entity for a data center that includes the computing platform, the request message received via an out-of-band (OOB) communication link and includes information directed to the software or the device driver;
• and
• forward the request message in one or more MCTP packets that indicate the assigned MCTP EID is a destination MCTP endpoint for the request message.

An apparatus comprising:

• an interface for a peripheral component interface express (PCIe) communication link coupled with a management controller for a computing platform;
• and
• circuitry of a processor for the computing platform, the circuitry to:
• receive assignment information for assignment of a domain mapped to physical memory addresses of one or more storage devices coupled with the computing platform to software or a device driver executed by a virtual machine (VM) to enable the software or the device driver to directly access, manage or control at least a portion of the one or more storage devices;
• send information to the management controller through the interface to indicate assignment of the domain to the software or the device driver;
• and
• receive, from the management controller, a multiple component transport protocol (MCTP) endpoint identifier (EID) for the domain that is for use by the software or the device driver to respond to request messages from a management entity for a data center that includes the computing platform, the request messages included in MCTP packets that indicate the MCTP EID as a destination MCTP EID for the request messages.
