Hi, i'm looking into virtio over MMIO. How does KVM know which guest memory region contains MMIO device registers? As i understand KVM exits the VM with KVM_EXIT_MMIO when MMIO memory is accessed and for that it should know where it is.
Anything that isn't RAM (which is registered with KVM_SET_USER_MEMORY_REGION) will cause KVM_EXIT_MMIO.
That said, this is not in topic for this mailing list. Paolo
