Hello, 

I created a new L4 setup with uvmm module and Linux kernel running on it.

I added also virtio-net-device and created new tap devices to be able to communicate with the VM from outside of L4.

The setup was done successfully and I could ping from my host machine to the Linux VM and vise versa.

The problem appeared when I accelerated the ping using -i option :

It continue pings for a few minutes then it gives (Destination Host Unreachable)!

I used the wrapper function vmm.start_virtio_switch() in me demo.

Why did this issue happen ? And how can I fix it?

Thanks,

Mohamed
