Hi, Chunhui:
Thanks for your reply.

I am studying OCP(Open Computer Platform) server board doc and OpenBMC doc.
I am just curious whether OCP server board also needs an add-on RMM component to support KVM/Media redirection.

So, OpenBMC’s current code has implemented KVM over IP.
So, OpenBMC would support KVM/Media redirection function without adding add-on some RMM like component?

Thanks

1. yes, it can implement the functionality with this combination
2. What platform are you using?

Hi, experts:
I have a question about KVM over IP and media redirection function.
Intel provided a RMM lite component, which provided KVM/Media redirection capability.

So my question is:

1.      OpenBMC + AST2500 Chip, could not implement KVM/Media redirection capability?

2.      If wanting to use KVM/Media redirection ,must buy a RMM component?

I found OpenBMC had implemented KVM over IP capability.

Thanks

Liu,

RMM is a HW licensing device, and was, if I recall, eliminated in the
last generation of Intel servers (i.e. S2600WF, S2600BNP, S2600SWP).
OpenBMC provides you all of the source, so any control over SW features
like KVM (assuming the KVM source is open), by HW components being
present can be compiled out of your implementation.
I have a hard time believing the OPC would willingly add a HW device for
enabling/disabling SW functionality. Seems a bit counter to the spirit
of the projects philosophy to me.

Johnathan,

S2600WF etc still has RMM enabled but openbmc implementation does not depend on RMM module. 

Tiger,

The OCP platform does not have RMM.  There is nothing preventing you from enabling KVM/Remote Media.

Do you have more specific questions? Are you porting OpenBMC to a platform you've developed, or are you just trying to use a system that has a BMC implementation base on OpenBMC?

Regardless, I've added Eddie in To: as he implemented the KVM support. If you are trying to support KVM on a platform you're developing then he can likely offer you some advice.

OpenBMC has no concept of an RMM component.

Hope that helps.

Andrew
