Send arping to the gateway instead of our own addressWe need to send an Unsolicited ARP to the gateway, instead of our own address. We now encounter problems when people deploy/destroy/deploy and get the same public ip. Packets arrive, but with incorrect / cached mac and are ignored by the routervm kernel. Run arping manually to update the arp-cache on the gateway and things start to work. Then we discovered the `arping` is actually done, but sent to its own address. Therefore the gateway doesn't pick it up. We only saw this happening when rapid deploy tools are used, like Terraform that do deploy/destroy/deploy and might get the same ip but on a new router having a new mac. ``` 2015-12-03 18:07:25,589 CsHelper.py execute:160 Executing: arping -c 1 -I eth1 -A -U -s 192.168.23.8 192.168.23.1 ``` The integration tests seem happy, although the full run is still ongoing: ``` === TestName: test_01_create_redundant_VPC_2tiers_4VMs_4IPs_4PF_ACL | Status : SUCCESS === ``` Thanks @sspans for helping trouble shoot this.

####################################################
Note there is a new systemvm build script based on
Veewee(Vagrant) under tools/appliance.
####################################################
1. The buildsystemvm.sh script builds a 32-bit system vm disk based on the Debian Squeeze distro. This system vm can boot on any hypervisor thanks to the pvops support in the kernel. It is fully automated
2. The files under config/ are the specific tweaks to the default Debian configuration that are required for CloudStack operation.
3. The variables at the top of the buildsystemvm.sh script can be customized:
IMAGENAME=systemvm # dont touch this
LOCATION=/var/lib/images/systemvm #
MOUNTPOINT=/mnt/$IMAGENAME/ # this is where the image is mounted on your host while the vm image is built
IMAGELOC=$LOCATION/$IMAGENAME.img
PASSWORD=password # password for the vm
APT_PROXY= #you can put in an APT cacher such as apt-cacher-ng
HOSTNAME=systemvm # dont touch this
SIZE=2000 # dont touch this for now
DEBIAN_MIRROR=ftp.us.debian.org/debian
MINIMIZE=true # if this is true, a lot of docs, fonts, locales and apt cache is wiped out
4. The systemvm includes the (non-free) Sun JRE. You can put in the standard debian jre-headless package instead but it pulls in X and bloats the image.
5. You need to be 'root' to run the buildsystemvm.sh script
6. The image is a raw image. You can run the convert.sh tool to produce images suitable for Citrix Xenserver, VMWare and KVM.
* Conversion to Citrix Xenserver VHD format requires the vhd-util tool. You can use the
-- checked in config/bin/vhd-util) OR
-- build the vhd-util tool yourself as follows:
a. The xen repository has a tool called vhd-util that compiles and runs on any linux system (http://xenbits.xensource.com/xen-4.0-testing.hg?file/8e8dd38374e9/tools/blktap2/vhd/ or full Xen source at http://www.xen.org/products/xen_source.html).
b. Apply this patch: http://lists.xensource.com/archives/cgi-bin/mesg.cgi?a=xen-devel&i=006101cb22f6%242004dd40%24600e97c0%24%40zhuo%40cloudex.cn.
c. Build the vhd-util tool
cd tools/blktap2
make
sudo make install
* Conversion to ova (VMWare) requires the ovf tool, available from
http://communities.vmware.com/community/vmtn/server/vsphere/automationtools/ovf
* Conversion to QCOW2 requires qemu-img
