Hi,
I write the data to the rx-ring and write the fd to notify the guest but there is no interrupts in the guest.
my notify code:
uint64_t kick_it = 1;
write(vring[0]->kickfd, &kick_it, sizeof(kick_it));
cat /proc/interrupts in the guest:
41: 0 PCI-MSI-EDGE virtio0-input
42: 0 PCI-MSI-EDGE virtio0-output
