The recently added overcommit feature breaks compatibility between older management servers
and 4.2 agents.
This patch fixes that by falling back if needed.
This is 1st patch for feature 'Support for VMware dvSwitch in CloudStack'.
This contains 3 newly introduced classes. Added apache license header for all 3 files.
[1]TrafficLable and [2]VmwareTrafficLabel classes are to define and encapsulate virtual switch type per traffic type along with other network label fields (VLAN ID and physical network).
[3]DistributedVirtualSwitchMO class is wrapper class for vSphere API calls specific to a distributed virtual switch in a vCenter datacenter.

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.
The issue happens randomly when hosts in a cluster gets distributed across multiple MS. Host can get split in following scenarios:
a. Add host – MS on which add host is executed takes ownership of the host. So if 2 hosts belonging to same cluster are added from 2 different MS then cluster gets split
b. scanDirectAgentToLoad – This runs every 90 secs. and check if there are any hosts that needs to be reconnected. The current logic of host scan can also lead to a split
The idea is to fix (b) to ensure that hosts in a cluster are managed by same MS. For (a) only the entry in the database is going to be created except in case if the host getting added is first in the cluster (in this case agent creation happens at the same time) and then (b) will take care of connection and agent creation part. Since currently addHost only creates an entry in the db there is a small window where the host state will be shown as 'Alert' till the time (b) is scheduled and picks up the host to make a connection. The MS doing add host will immediately schedule a scan task and also send notification to peers to start the scan task.
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.
