Problem: Not able to configure a sort order for the zones that are listed in various views in the UI.
Root Cause: There is no mechanism to accept sort key for existing zones or UI widget, that would allow to listing zones in the UI in a certain order.
Solution: The order of zones in listed in various views in the UI can now be configured through the newly added “sort_key” field added for the zone. It can be set using updateZone API by providing “sort_key” parameter for a zone, or by reordering the items in the zones list in the UI. UI has been updated to show ordering controls in zones list view. Database changes include updating table “data_center” by adding “sort_key” column (containing integer values and defaults to zero).

Problem: Admins don’t want to charge for IP address usage on certain (shared) networks.
Root Cause: There is no flag or detail for admins to provide using UI or API when creating networks to specify if they want IP address usage of the network hidden.
Solution: A new boolean hideipaddressusage flag is added to the createNetwork API and a checkbox in the ‘Add guest network’ UI for the root admins to specify if they want the shared network’s IP address usage to be hidden in the listUsageRecords API response. The provided flag is saved as the ‘hideIpAddressUsage’ detail in the cloud.network_details table for the network. For existing (shared) networks, root admins can also specify the same boolean API parameter hideipaddressusage with the updateNetwork API request to configure the behaviour for an existing network. When the detail/flag is true, the IP address usage for the (shared) network is not exported in the listUsageRecords API response. The listNetworks API response will include the details of a network for root admin only. (note usage is still recorded in the usage database but not return by the listUsageRecords API)
The API flag works for any kind of network via the API, but the checkbox is only shown while creating shared networks in the UI.

Feature Specification: https://cwiki.apache.org/confluence/pages/viewpage.action?pageId=95653548
Live storage migration on KVM under these conditions:
From source and destination hosts within the same cluster
From NFS primary storage to NFS cluster-wide primary storage
Source NFS and destination NFS storage mounted on hosts
In order to enable this functionality, database should be updated in order to enable live storage capacibilty for KVM, if previous conditions are met. This is due to existing conflicts between qemu and libvirt versions. This has been tested on CentOS 6 hosts.
Additional notes:
To use this feature set the storage_motion_supported=1 in the hypervisor_capability table for KVM. This is done by default as the feature may not work in some environments, read below.
This feature of online storage+VM migration for KVM will only work with CentOS6 and possible Ubuntu as KVM hosts but not with CentOS7 due to:
https://bugs.centos.org/view.php?id=14026https://bugzilla.redhat.com/show_bug.cgi?id=1219541
On CentOS7 the error we see is: " error: unable to execute QEMU command 'migrate': this feature or command is not currently supported" (reference https://ask.openstack.org/en/question/94186/live-migration-unable-to-execute-qemu-command-migrate/). Reading through various lists looks like the migrate feature with qemu may be available with paid versions of RHEL-EV but not centos7 however this works with CentOS6.
Fix for CentOS 7:
Create repo file on /etc/yum.repos.d/:
[qemu-kvm-rhev]
name=oVirt rebuilds of qemu-kvm-rhev
baseurl=http://resources.ovirt.org/pub/ovirt-3.5/rpm/el7Server/
mirrorlist=http://resources.ovirt.org/pub/yum-repo/mirrorlist-ovirt-3.5-el7Server
enabled=1
skip_if_unavailable=1
gpgcheck=0
yum install qemu-kvm-common-ev-2.3.0-29.1.el7.x86_64 qemu-kvm-ev-2.3.0-29.1.el7.x86_64 qemu-img-ev-2.3.0-29.1.el7.x86_64

Problem: When a multi-disk OVA template is uploaded, only the root disk is recognized and VMs deployed using such template only get the root disk provisioned.
Root Cause: The template processor for multi-disk OVA was not used in the template upload processor.
Solution: Added support for local multi-disk OVA template upload. After a multi-disk OVA template is
uploaded, the mechanism that worked on multi-disk OVA templates registered using URL is now also used to discovers and creates data-disk templates in cloud.vm_template table and on the secondary storage.
To enable SSL on SSVMs :
• Upload the certificates like you usually do via the API or UI->Infrastructure tab
• Set the global settings secstorage.encrypt.copy, secstorage.ssl.cert.domain to appropriate values
along with the CPVM ones
• Restart management server (no need to destroy/restart SSVM (or the ssvm agent))
Test cases:
- Upload template and check it creates multi-disk folders on secondary
storage and entries in cloud.vm_template table
- Upload template and kill/shutdown management server. Then restart MS
to check if template sync works
- Copy template across zone of an uploaded template

This PR is for deactivating Ehcache in CloudStack since it is not usable. The first commit remove the default RMI cache peering configured for multicast which most of the time cannot work. It also requires to have an interface up which is not always the case while developing offline.
The second commits remove the configuration to activate caching on some DAOs.
Problems
The code in CS does not seem to fit any caching mechanism especially due to the homemade DAO code. The main 3 flaws are the following:
Entities are not expected to be shared
There is quite a lot of code with method calls passing entity IDs value as long, which does some object fetching. Without caching, this behavior will create distinct objects each time an entity with the same ID is fetched. With the cache enabled, the same object will be shared among those methods. It has been seen that it does generate some side effects where code still expected unchanged entity attributes after calling different methods thus generating exception/bugs.
DAO update operations are using search queries
Some part of the code are updating entities based on a search query, therefore the whole cache must be invalidated (see GenericDaoBase: public int update(UpdateBuilder ub, final SearchCriteria<?> sc, Integer rows);).
Entities based on views joining multiple tables
There are quite a lot of entities based on SQL views joining multiple entities in a same object. Enabling caching on those would require a mechanism to link and cross-remove related objects whenever one of the sub-entity is changed.
Final word
Based on the previously discussed points, the best approach IMHO would be to move out of the custom DAO framework in CS and use a well known one (out of scope of this change of course). It will handle caching well and the joins made by the views in the code. It's not an easy change, but it will fix along a lot of issues and add a proven / robust framework to an important part of the code.
Since the CloudStack virtual router was redesigned on version 4.6 it has been observed that the DHCP leases file is not persistent across network operations. This causes conflicts on guest VMs static IPs, causing these static IPs to not be renewed by the DHCP server running on isolated and VPC networks' virtual routers (dnsmasq). On stopping or destroying a VM, its dhcp/dns records are not removed from the virtual router causing ghost effects.

This commit simplifies the generateDestPath method and fixes an issue where an extra file, named as 'null', was created on the target storage pool during VM local storage volume migration. Without this fix, the VM is migrated and there is no data loss; however, 193 KB is allocated for the unused file named as 'null' and the file stays on the target storage.

Allows creating storage offerings associated with particular domain(s) and zone(s). In create disk/storage offfering form UI, a mult-select control has been addded to select desired zone(s) and domain select element has been made multi-select.
createDiskOffering API has been modified to allow passing list of domain and zone IDs with keys domainids and zoneids respectively. These lists are stored in DB in cloud.disk_offering_details table with 'domainids' and 'zoneids' key as string of comma separated list of IDs. Response for create, update and list disk offering APIs will return domainids, domainnames, zoneids and zonenames in details object of offering.
listDiskOfferings API has been modified to allow passing zoneid to return only offerings which are associated with the zone.

Problem: Custom compute offering does not allow setting min and max values for CPU and VRAM for custom VMs.
Root Cause: Custom compute offerings cannot be created with a given range of CPU number and memory instead it allows only fixed values.
Solution: createServiceOffering API has been modified to allow setting a defined range for CPU number and memory. Also, UI form for compute offering creation is provided with a new field named 'compute offering type’ with values - Fixed, Custom Constrained, Custom Constrained. It will allow the creation of compute offerings either with a fixed CPU speed and memory for fixed compute offering, or with a range of CPU number and memory for custom constrained compute offering or without predefined CPU number, CPU speed and memory for custom unconstrained compute offering.
To allow the user to set CPU number, CPU speed and memory during VM deployment, UI form for VM deployment has been modified to provide controls to change these values. These controls are depicted in screenshots below for custom constrained and custom unconstrained compute offering types.
Sample API calls using cmk to create a constrained service offering and deploying a VM using it,
create serviceoffering name=Constrained displaytext=Constrained customized=true mincpunumber=2 maxcpunumber=4 cpuspeed=400 minmemory=256 maxmemory=1024

With this patch b766bf7
we started tracking disks in attaching state so that other attach request can fail gracefully. However this missed the case where disks were in allocated state but attach was requested.
For the use case where users want to attach disk in allocated state but not ready, we need to have allocated-attaching transition as well. We must take care of returning to the original state - allocated or ready - when attach request has completed.
For the use case of unstarted vm's the disk must proceed as follows - "Allocated" -> Attaching -> Allocated. When VM is started, the disk is "created" and pool is assigned. For the use case of started VMs it's more trivial and disk proceeds as follows - Ready -> Attaching -> Ready.
Test this by creating a VM with "startvm=false", create a disk and try attaching it in allocated state. It would give an exception on latest 4.11 but will be fixed on this patch.

Problem: Users are billed for destroyed VMs with VM snapshots because usage records don't get that the VM and VM snapshots are removed.
Root Cause: The destroyVirtualMachine and expungeVirtualMachine APIs were removing VM snapshots but not generating VMSNAPSHOT.DELETE usage event due to which the VM snapshots were not marked as removed in the usage_vmsnapshot table.
Solution: The issue was fixed by emitting the proper usage event for all the VM snapshots of a VM that is destroyed.
