CloudStack uses Guest CIDR for dhcp-range for the Guest VMs. The entire
CIDR is used by CloudStack for assigning IPs to Guest VMs. IP Address
Reservation will allow part of address space to be used fornon CloudStack
hosts/physical servers also, by restricting the address space of CloudStack
Guest VMs. Reservation can be configured using update Network API by specifying
guestvmCidr as an additional parameter. Reservation will be applicable for
Isolated Guest Networks including VPC. reservediprange in the response
will return the IP range that can be used for non Cloudstack hosts.
Tested manually the following scenarios:
Applying reservation when there are running VMs inside the
guest_vm_cidr.
Applying reservation when there are running VMs outside the
guest_vm_cidr.(not allowed)
Applying reservation when external device like Netscaler is configured
in the guest_cidr.
Applying reservation in VPC tiers.
Applying reservation outside the range of guest_cidr.(not allowed)
Addition of two new resource types i.e. CPU and Memory in the existing pool of
resource types.
Added some methods to set the limits on these resources using updateResourceLimit
API command and to get a count using updateResourceCount. Also added calls in the
Virtual machine life cycle to check these limits and to increment/decrement the new
resource types
Resource Name :: Resource type number
CPU 8
Memory 9
Also added Unit Tests for the same.
The new policy is:
1. Generate a random IP.
2. Find the next available IP, start from the generated IP.
3. If we cannot find an available IP after certain times(10000 by default,
network.ipv6.search.retry.max) retry, give up.
following changes
- introduced notion of event bus with publish, subscribe, unsubscribe
semantics
- a plug-in can implement the EventBus abstraction to provide event
bug to CloudStack
- A rabbitMQ based plug-in that can interact with AMQP servers to
provide message broker based event-bug
- stream lines, action events, usage events, alerts publishing in to
convineance classed which are also used to publish corresponding
event on to event bus
- introduced notion of state change event. On a state change, in the
state machine corrsponding to the resource, a state change event is
published on the event bug
- associated a state machined with Snapshot and Network objects
- Virtual Machine, Volume, Snaphost, Network object state changes wil
result in a state change event
This feature provides resetting a SSH key for an existing VM which means,
setting the old ssh key that is assigned to the VM previously with the new ssh
key.

Description: Adds API calls updateDefaultNicForVirtualMachine,
addNicToVirtualMachine, and removeNicFromVirtualMachine. These are
intended to allow a user to modify a VM's configuration post
deployment, to adjust the networks to which the VM belongs.

By moving it to the api project, it lessens the dependency of plugins on the server components.

NetworkManager's exclusive focus is now
- handling plugins during orchestration, and
- to deal with ip address allocation.
Those classes that used to refer to NetworkManager to get access to the datamodel now refer to NetworkModel

The basic idea behind this is, deploy a fix sized threadpool for updating RvR
status, then using producer/consumer model. There is a global configuration
router.check.poolsize(10 by default) to control the pool size.
Using pool size 100 for 1000 RvR is tested with simulator and works well.
Also we can adjust the global configuration option router.check.interval to e.g.
60s from default 30s to mitigate the issue.
For LB device in inline mode, the ip deployer(the owner of public ip) is the
firewall in front of it, not itself. So check if it's inline or not, if it's
inline, return the firewall as ip deployer
Details:
- changed associateIPAddr API to accept shared network Id and account Id. Ip will be owned by tuple (account Id, network Id)
- chaged createNetwork API to accpet CIDR when network offering has external networking device providers
Bug ID:CLOUDSTACK-312 enable L4-L7 network services in the shared
network in the advanced zone
- Refactor VPN and VM APIs to admin and user pkgs
- Names space, org.apache.cloudstack
- Fix refactored apis in commands*.in
- Fix comments etc.
- Expand tabs, remove trailing whitespace

The code that would propage userdata to router, when updateVirtualMachine api
is called, was missing. As per the docs [0], userdata should be a base64 encoded
string upto 2KB which is put on domr's html directory adn using HTTP GET the
userdata information can be obtained from the domr.
The updateVirtualMachine api [0] would accept a base64 encoded string
and decoded and put into the domr's /var/www/html/userdata/<uservm ip>/user-data
file. The operation does not require the VM to be in stopped state, though it is
advised to stop and call this api in case the user vm has a script which gets
the userdata information from domr while starting.
For example, this script can be used to fetch the data:
server_ip=$(grep dhcp-server-identifier /var/lib/dhclient-eth0.leases | tail -1 | awk '{print $NF}' | tr '\;' ' ')
wget http://${server_ip}/latest/user-data
This feature can be useful, for example to use into puppet facts [1], or to do
automation and horizontal scaling etc. based on userdata.
