Changes:
- Enabled updating storage tags
- All existing tags are wiped out and new ones provided are stored.
- Note that, if tags are updated on the storage, no changes are done to the deployment of already running VMs that were deployed prior to tag addition.
- Also added some validation to host tags update API.
As per the new design following would be done.
(a) any ISO-derived disk can be extracted
(b) there will be a global config to disable extraction of ISO based volumes.
That way people concerned about (a) can just use (b) to fix it.

Changes:
- Added a two new deployment planners 'UserDispersingPlanner' and 'UserConcentratedPodPlanner' to the DeploymentPlanners
- Planner can be chosen by setting the global config variable 'vm.allocation.algorithm' to either of the following values:
('random', 'firstfit', 'userdispersing', 'userconcentratedpod')
- By default, the value is 'random'. When the value is 'random', FirstFitPlanner is invoked as before that shuffles the resource lists.
- Now Admin can choose whether the deployment heuristic should be applied starting at cluster or pod level. This can be done by using the
global config variable 'apply.allocation.algorithm.to.pods' which is false by default. Thus by default as earlier, planner starts at clusters directly.
'UserConcentratedPodPlanner' changes:
- Earlier to 3.0, FirstFitPlanner used to reorder the clusters in case this heuristic was chosen.
- Now this is done by a separate planner and is applied only when 'vm.allocation.algorithm' is set to this planner
- It reorders the capacity based clusters/pods such that those pods having more number of Running Vms for the given account are tried first.
- Note that this userconcentration is applied only to pods and clusters. Not to hosts or storagepools within a cluster.
'UserDispersingPlanner' changes:
- 'UserDispersingPlanner' reorders the capacity ordered pods and clusters based on number of 'Running' VMs for the given account in ascending order. Aim is to choose thodes pods/clusters first which have less number of Running VMs for the given account
- Admin can provide weights to capacity and user dispersion so that both parameters get considered in reordering the pods/clusters. This can be done by setting
the global config parameter 'vm.user.dispersion.weight'. Default value is 1. Thus if this planner is chosen, by default, ordering will be done only by number of Running Vms, unless the weight is changed.
- HostAlllocators and StoragePoolAllocators also reorder the hosts and pools by ascending order of number of Running VMS/ Ready Volumes respectively for the given account. Thus try to choose that host or pool within a cluster with less number of VMs for the account.
listSupportedNetworkServiceProviders returs list of services with providers and capabilities of each service.
It supports 2 parameters:
-service : list providers and capabilities of this service
-provider: list services of this provider
- if none is specified, lists all services supported
-made Netscaler, SRX, F5 network elements as pluggable service
-added abstract load balancer device manager ExternaLoadBalancerDeviceManager
-made both F5 and Netscaler pluggable service to extend ExternaLoadBalancerDeviceManager
-added abstract firewall device manager ExternalFirewallDeviceManager
-made SRX pluugable service to extende ExternalFirewallDeviceManager
-added API's to configure and manage netscaler devices
- not use includingRemoved while listing networks
- Processing checkNetworkCommand dummy method to avoid failures connecting to Vmware and hyperv resource
* update network with new networkOfferingId only after the network is shutdown
* fixed NPE happenining when updateNetwork with the networkOffering w/o soucrceNat service in Advance zone
only owner of the network can access it; if it's domain - all accounts in the domain and domain children can have an access.
* aclType replaces 2 old fields: isShared and isDomainSpecific.
* All 2.2.x account specific networks will have aclType=Account; 2.2.x Domain specific networks - aclType=domain; 2.2.x Zone level networks - aclType=Domain with domainId = Root domain id
- Create Default physicalnetwork and add traffic types while creating a zone
- DeleteProvider should error out if there are networks using the provider.
- Other validations
- ListSupportedNetworkServiceProvidersCmd will now return Providers along with its element's services and boolean 'canEnableIndividualServices' that indicates if for this Provider services can be enabled/disabled
- add & update NetworkServiceProvider changed to take in the list of services to enable. While adding a provider, if list is null then all services supported by the element are enabled by default.
- ListNetworkServices enhanced to take in a provider name and returns services of that specific provider.
* can be specified for Shared network only
* if not specified for the Shared networks, try to locate it based on the zoneId and tags. If tags is not null, pick up first physicalNetwork from the zone that has matching tags. If tags is null, and there are none/more than 1 physical netwroks in the zone, error out.
As DhcpElement/VirtualRouterElement/RedundantVirtualRouterElement is decided to
be the service provider of the physical network, this API should be called to
add a new element, with correlated network service provider ID.
Then e.g. ConfigureVirtualRouterElementCmd should be called to configure and
enable the element.
Added PortForwardingServiceProvider, StaticNatServiceProvider, rename
PasswordServiceProvider to UserDataServiceProvider(may rename to a better name
later).
Add related function for service providers.
DHCP range, domain name, etc. are the property of network, not virtual router
specific.
The focus of virtual router configuration would on separate enable/disable each
service it provided.
2)Re-apply all existing firewall rules as a part of implement call. TODO: Cleanup all existing rules from the backend (leave them in the DB) as a part of shutdown call
1. able to restore VM from its original template
2. Only allow to restore when VM is running or stopped
3. after restoring, VM state will not change, e.g. running is still running
status 9949: resolved fixed
TODO:
- Still leaving the provider columns in data_center schema as-is for CloudKit and BareMetal
- ExternalNetworkDeviceMgrImpl still needs to fix the dataCenter.setProviders calls and externalNetworkApplicance usage checks to see if zone has external networking.
Limitations:
* can't upgrade to the network offering with lesser number of services
* can upgrade only when the service provider of the original offering is not external (domR, dhcp, elb) to the external type of the provider
-Bringing add/delete/list of all external network devices under one unified API's (addNetworkDevice, deleteNetworkDevice, listNetworkDevice)
-Refactoring External network manager to work from both sets of API's add/delete/list NetworkDevice and add/delete/list External Firewall/LoadBalancer
- Make all API commands Async and add events
- Make BroadcatsDomainRange case insensitive
- Process all _networkElements to build the Service -> Provider map during NetworkMgr::configure()
Add configure command for these virtual router based elements. The commands
should be different for different elements.
The context of configuration would be added later.
- Create Zone changes and changes to data_center table to remove vlan, securityGroup fields
- Physical Network lifecycle APIs
- Physical Network Service Provider APIs
- DB schema changes
* moved all services to the separate table, map them to the network_offering+provider.
* added state/securityGroupEnabled properties for the networkOffering
* added ability to list by state/securityGroupEnabled in listNetworkOfferings api command
2) New service: SourceNat
Changes:
- Added a new interface 'PluggableService'
- Any component that can be packaged separately from cloudstack, can implement this interface and provide its own property file listing the API commands the component supports
- As an example have made VirtualNetworkApplianceService pluggable and a new configureRouter command is added
- ComponentLocator reads all the pluggable service from componentLibrary or from components.xml and instantiates the services.
- As an example, DefaultComponentLibrary adds the pluggable service 'VirtualNetworkApplianceService'
- Also components.xml.in has an entry to show how a pluggable service can be added, but it is commented out.
- APIServer now reads the commands for each pluggable service and when a command for such a service is called, APIServer sets the required instance of the pluggable service in the coomand.
- To do this a new annotation '@PlugService' is added that is processed by APIServer. This eliminates the dependency on the BaseCmd to instantiate the service instances.
Since we would introduce a way to specify each service provider in the network
offering, it's better for redundant virtual router as a separate service
provider.
Also isRedundant() flag in the network offering would be removed. Redundant
virtual router temporality won't work from now. Until we're able to add
different network elements/service providers in network_offering.
In the past, the NetworkElement would cover almost all the functionality that
e.g. virtual router can cover: firewall, source NAT, static NAT, password,
VPN... So anyone want to implement the NetworkElement would have to implement
these service's specific methods, even it wouldn't support it. Also, if we want
to find a e.g. FirewallServiceProvider, we have to proceed all the current
network service providers, to call a method to know if it support such service.
That's neither elegant nor scaling way to do it.
As the first step, this patch separates each ServiceProvider from NetworkElement
(there are some interface already out of NetworkElement, so this patch slightly
modifies them too), and only the class would implement the correlated interface, would
have the ability to do these services.
