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
