The new CA framework introduced basic support for comma-separated
list of management servers for agent, which makes an external LB
unnecessary.
This extends that feature to implement LB sorting algorithms that
sorts the management server list before they are sent to the agents.
This adds a central intelligence in the management server and adds
additional enhancements to Agent class to be algorithm aware and
have a background mechanism to check/fallback to preferred management
server (assumed as the first in the list). This is support for any
indirect agent such as the KVM, CPVM and SSVM agent, and would
provide support for management server host migration during upgrade
(when instead of in-place, new hosts are used to setup new mgmt server).
This FR introduces two new global settings:
- `indirect.agent.lb.algorithm`: The algorithm for the indirect agent LB.
- `indirect.agent.lb.check.interval`: The preferred host check interval
for the agent's background task that checks and switches to agent's
preferred host.
The indirect.agent.lb.algorithm supports following algorithm options:
- static: use the list as provided.
- roundrobin: evenly spreads hosts across management servers based on
host's id.
- shuffle: (pseudo) randomly sorts the list (not recommended for production).
Any changes to the global settings - `indirect.agent.lb.algorithm` and
`host` does not require restarting of the mangement server(s) and the
agents. A message bus based system dynamically reacts to change in these
global settings and propagates them to all connected agents.
Comma-separated management server list is propagated to agents on
following cases:
- Addition of a host (including ssvm, cpvm systevms).
- Connection or reconnection by the agents to a management server.
- After admin changes the 'host' and/or the
'indirect.agent.lb.algorithm' global settings.
On the agent side, the 'host' setting is saved in its properties file as:
`host=<comma separated addresses>@<algorithm name>`.
First the agent connects to the management server and sends its current
management server list, which is compared by the management server and
in case of failure a new/update list is sent for the agent to persist.
From the agent's perspective, the first address in the propagated list
will be considered the preferred host. A new background task can be
activated by configuring the `indirect.agent.lb.check.interval` which is
a cluster level global setting from CloudStack and admins can also
override this by configuring the 'host.lb.check.interval' in the
`agent.properties` file.
Every time agent gets a ms-host list and the algorithm, the host specific
background check interval is also sent and it dynamically reconfigures
the background task without need to restart agents.
Note: The 'static' and 'roundrobin' algorithms, strictly checks for the
order as expected by them, however, the 'shuffle' algorithm just checks
for content and not the order of the comma separate ms host addresses.

* [CLOUDSTACK-10240] ACS cannot migrate a volume from local to shared storage.
CloudStack is logically restricting the migration of local storages to shared storage and vice versa. This restriction is a logical one and can be removed for XenServer deployments. Therefore, we will enable migration of volumes between local-shared storages in XenServers independently of their service offering. This will work as an override mechanism to the disk offering used by volumes. If administrators want to migrate local volumes to a shared storage, they should be able to do so (the hypervisor already allows that). The same the other way around.
* Cleanups implemented while working on [CLOUDSTACK-10240]
* Fix test case test_03_migrate_options_storage_tags
The changes applied were:
- When loading hypervisors capabilities we must use "default" instead of nulls
- "Enable" storage migration for simulator hypervisor
- Remove restriction on "ClusterScopeStoragePoolAllocator" to find shared pools

There is a race condition in the monitoring of the migration process on KVM. If the monitor wakes up in the tight window after the migration succeeds, but before the migration thread terminates, the monitor will get a LibvirtException “Domain not found: no domain with matching uuid” when checking on the migration status. This in turn causes CloudStack to sync the VM state to stop, in which it issues a defensive StopCommand to ensure it is correctly synced.
Fix: Prevent LibvirtException: "Domain not found" caused by the call to dm.getInfo()
The ACL rules editing/addition page is not user-friendly. Users are not able to see in a single view all of the detail of the ACL rule (they need to use a scroll bar on the horizontal). The problem becomes worse when there are a considerable number of rules. Therefore, we are proposing the following changes:
1- Instead of using the table to create new ACL, we can create a button like the one presented in attached pictures, where users can click, and then a modal popup would appear and users would be able to create the new ACL there. This is similar to the workings of the ACL edit button.
2 - Remove the ability to add new ACL via table where they are presented. All ACLs should be entered via the “New ACL” button. Therefore, the section “Add ACL” would be removed as well;
3 - Move the action section of the list ACL table to the most left position;
These changes would reduce the information in the table and facilitate users to add new rules and easily edit them as well.
