Thanks for the recommendation. I will put the sleep into vmbus_init to ensure all channels are ready before the vmbus_init function exits. > > hv_cb_utils[HV_SHUTDOWN_MSG].channel->OnChannelCallback = > > &shutdown_onchannelcallback; > > The problem is that you just have a bunch of callbacks you are setting > up, it's not a "real" function call.

Actually, we already assign a default callback function, chn_cb_negotiate(), when the channels are opened in vmbus module. It's a real function and can handle common negotiation messages. I will move the sleep into vmbus module as well.
