Hi,
Iam just studying the faqs but i cannot find a valid answer to this
specific question about the subject topic.I have a Virtual KVM-Instance
running and iam curious about the internals and how the packets are
routed from the physical (hostsystem) layer to the Internal, virtual
Guest interface (virtio, e1000, rtl). Iam talking about ethernet and
IP/TCP/UDP/ICMP Data only.
"How" is an inboud packet, reaching the kvm hosts physical ethernetcard
hardware forwarded to the virtual networkcard inside the guest os and
what is happening if the guest os firewall admin decides to
drop/reject/accept the packet?
1) Will the KVM-Hostsystem drop this packet physically?
2) Is the KVM-Guest OS dropping the packet at the virtual guest network
adapter?
(and if so, what data remains inside the KVM Hostsystem memory, at the
host nic driver level after a guest os singanls to drop the virtual packet?)
Are there docs out there where i can study the details?
cheers, dc
