回复： how the openbmc running in qemu communicate with the operating system running in another qemu via KCS/BT?

[南野ムルシエラゴ]

Hi, Stephen


Thanks for your help, I have handled how the client like ipmitool to communicate with openbmc via net. As Andrew said my problem is how openbmc communicate with host in qemu environment.
ipmitool<------stage 1 OK------->openbmc<------stage 2 NOT OK------>host


Best Regards!
Liu Hongwei

I think what Liu was asking about was setting up in-band IPMI between two guests
(e.g. one BMC guest and one host guest). Your description covers network IPMI
between a management client and the BMC guest.
