Hi Du Jun, You can find my thread here http://mail-archives.apache.org/mod_mbox/cloudstack-users/201310.mbox/thread?5, I was having the exact same issue. My conclusion "It appears upgrading (Linux) VM kernels to 3.5 fixed the Inbound traffic issue. Drivers for e1000 on Windows are (apparently) provided by Microsoft but are the latest version. I have a feeling this issue was brought in a few KVM releases ago."
To use Windows VMs I would recommend changing their OS Type in Cloudstack to, 'Other PV'. 'Windows PV' may also work but I have not tested it.
