Hi Kernel KVM folks and Michael, I am trying to make VHOST-BLK to work by myself since I did not hear from Asias on my personal mail to him. I will be grateful to you for your time and response. The problem I am seeing is there is no response seen by the VM through the HOST has executed the IO successfully and issued vhost_add_used_and_signal. Here is my question. Which code in QEMU issues

Extend virtio to support many interrupt vectors, and rearrange code in preparation for multi-vector support (mostly move reset out to bindings, because we will have to reset the vectors in transport-specific code). Actual bindings in pci, and use in net, to follow. Load and save are not connected to bindings yet, so they are left stubbed out for now. Signed-off-by: Michael S. Tsirkin <mst at
