I use cloudstack4.1 basic network.
When I use tcpdump to capture packets on the management nic of the host node,it 
will be like this:

[root@cs-kvm02 opt]# tcpdump -c 10000 -w /test.pcap -vv
tcpdump: listening on cloudbr0, link-type EN10MB (Ethernet), capture size 65535 
bytes
10000 packets captured
10515 packets received by filter
481 packets dropped by kernel

I don't know if it is normal,I think it should be "0 packets dropped by kernel".
