normally, in dhcp reply, the target ip is allocated ip for VM.
but windows 2008 32bit has special field in dhcp reply, which makes dhcp reply use 255.255.255.255 as target ip, which is blocked by SG rule,
createipAlias.sh/deleteipAlias.sh won't be copied to XenServer host.
The directory of the scripts should be ".." rather "../../.." in all the xenserver patches file.
Corrected the path to ".." because the scripts are located at scripts/vm/hypervisor/xenserver/xenserver56/patch
Fixed by updating the patch files that has
entries to copy scipts on xenserver. Here we added
Add-To-VCPUs-Params-Live.sh
Added a check on Host params whether host restricts Dynamic memory control(DMC) to able to allow scale up VM.
If DMC is not enabled then static max and min are set to SO.

This feature enables adding of guest ip ranges (public ips) form different subnets.
In order to provide the dhcp service to a different subnet we create an ipalias on the router. This allows the router to listen to the dhcp request from the guest vms and respond accordingly. Every time a vm is deployed in the new subnet we configure an ip alias on the router. Cloudstack uses dnsmasq to provide dhcp service. We need to configure the dnsmasq to issue ips on the new subnets. Added a new class dnsmasqconfigurator which generates the dnsmasq confg file, this file replaces the old config in the router.
The details of the alias ips are stored in db in the nic_ip_alias table. Every time a new subnet is added one of the ip from the subnet is used to configure the ip alias.
I have pushed the code to https://github.com/bvbharatk/cloud-stack/tree/Cloudstack-702 , also rebased the code with master.
I need to test the code for advanced sg enabled network using kvm.
I have added the unit test
Marvin tests are at https://git-wip-us.apache.org/repos/asf?p=cloudstack.git;h=53e4965
Also accomodated some of the changes suggested by koushik.
corrected the import statements. renamed the IpAlias command to createIpAlias command.
This feature supports only ipv4
Start/stop vm/dhcp server are done. Not done with VM migration.
A new command(PvlanSetupCommand) is sent for setting up PVLAN for vms. Currently
it's focus on OVS implementation. Need to be more abstruct and add vSwitch part.
Detail: Added exception handling around iptables chain flushing, along
with a call to default_network_rules() to re-initialize.
Testing:
On agent, ls /var/run/cloud and pick one of the VMs to test with. Make a
backup of it's logfile (eg cp /var/run/cloud/i-2-1722.log /tmp )
Destroy the firewall ruleset for that VM with
/usr/lib64/cloud/common/scripts/vm/network/security_group.py destroy_network_rules_for_vm --vmname i-2-1722-VM --vif vnet10
Now copy the log file back, edit the file and decrement the last field by 1
ACS should notice the out-of-date sequence ID and push a new ruleset for
the VM within 60 seconds.

Detail: This gets rid of the patchdisk method of passing cmdline and
authorized_keys to KVM system VMs. It instead passes them to a virtio socket,
which the KVM guest reads from the character device /dev/vport0p1 during
cloud-early-config. Tested to work on CentOS 6.3 and Ubuntu 12.04. Should
work with even older versions of libvirt.

cause writing the heartbeat to take longer than expected. By comparing
the last successful heartbeat epoch with the current epoch we check if
the timeout value has been met.
Checks the args length, doesn't throw IndexError when no args
passed. Also logs to security_group.log when executed with no args or unknown
command.
