hi, all
I have a question regarding KVM's networking stack implementation.
Does KVM hook into NetFilter to intercept packets destined for the guest, or PF_PACKET?
Thanks for your help, in advance
Regard, Kangkook

None of the above.
With -net user, KVM uses techniques derived from SLiRP to simulate a
network stack with only traditional userspace UNIX socket calls. With
-net tap, it uses the standard ethertap interface. -net socket and -net
dump likewise do nothing unconventional.
