I mean whatever combination didn't work for your custom vhost module.
If vhost_net is broken too there is probably a vhost/QEMU bug that
should be fixed.

Do you mean vhost_net - old kernel, qemu - latest, guest - latest?

Does vhost_net work with the old kernel + new QEMU combo?
Stefan
Both. The compiled kernel was common for both.

Old guest kernel or old host kernel?
New QEMU should support old guest kernels. Maybe you ha
I have managed to deal with it.
The thing is I was using one of the latest versions of qemu, but an
old Linux Kernel version of 3.12.

My vhost module respects the format vhost-net uses:
/* summary */
mutex_lock(&vq->mutex);
vhost_disable_notify();
for (;;) {
head = vhost_get_vq_desc();
if (head == vq->num) {
if (unlikely(vhost_enable_notify())) {
vhost_disable_notify();
