Hi everyone, I''m trying to understand the flow of control and how the VMs are scheduled while doing network I/O. Say a guest OS is trying to send a packet. So it gets scheduled, and the front-end driver places the packet in the IO descriptor ring. Thereafter, the back end domain (in this case dom0) gets scheduled, picks up the packet and sends it out on the NIC. Is this correct? So if I were to take a tcpdump on dom0 and plot a timeline of events as the VM gets scheduled, I should see the VM get scheduled, then dom0 and while dom0 is running tcpdump should see a packet getting sent out on the NIC?
