This extends securing of KVM hosts to securing of libvirt on KVM
host as well for TLS enabled live VM migration.
Based on whether keystore and certificates files are available at
/etc/cloudstack/agent, the KVM agent determines whether to use TLS or
TCP based uris for live VM migration. It is also enforced that a secured
host will allow live VM migration to/from other secured host, and an
unsecured hosts will allow live VM migration to/from other unsecured
host only.
Post upgrade the KVM agent on startup will expose its security state
(secured detail is sent as true or false) to the managements server that
gets saved in host_details for the host. This host detail can be accesed
via the listHosts response, and in the UI unsecured KVM hosts will show
up with the host state of ‘unsecured’. Further, a button has been added
that allows admins to provision/renew certificates to KVM hosts and can
be used to secure any unsecured KVM host.
The `cloudstack-setup-agent` was modified to accept a new flag ‘-s’
which reconfigured libvirtd with following settings that enables only
TLS:
listen_tcp=0
listen_tls=1
tcp_port="16509"
auth_tcp="none"
tls_port=”16514”
auth_tls=”none”
key_file = "/etc/pki/libvirt/private/serverkey.pem"
cert_file = "/etc/pki/libvirt/servercert.pem"
ca_file = "/etc/pki/CA/cacert.pem"
For a connected KVM host agent, when the certificate are
renewed/provisioned a background task is scheduled that waits until all
of the agent tasks finish after which libvirt process is restarted and
finally the agent is restarted via AgentShell.
There are no API or DB changes.

This implements an out-of-band management plugin for nested-cloudstack
environments where the hypervisor host is a VM in a parent CloudStack environment
that is used as a host in the (testing) CloudStack environment. This plugin
allows power operations to translate into start/stop/reboot of the VM (host).
The out-of-band management configuration accepted are:
- Address: The API URL of the parent CloudStack enviroment
- Port: The uuid of the (host) VM in the parent CloudStack environment
- Username: The apikey of the user account who has ownership on the (host) VM
- Password: The secretkey of the user account who has ownership on the (host) VM
Note: change password of the oobm interface is not support by this plugin

Host-HA offers investigation, fencing and recovery mechanisms for host that for
any reason are malfunctioning. It uses Activity and Health checks to determine
current host state based on which it may degrade a host or try to recover it. On
failing to recover it, it may try to fence the host.
The core feature is implemented in a hypervisor agnostic way, with two separate
implementations of the driver/provider for Simulator and KVM hypervisors. The
framework also allows for implementation of other hypervisor specific provider
implementation in future.
The Host-HA provider implementation for KVM hypervisor uses the out-of-band
management sub-system to issue IPMI calls to reset (recover) or poweroff (fence)
a host.
The Host-HA provider implementation for Simulator provides a means of testing
and validating the core framework implementation.

Support access to a host’s out-of-band management interface (e.g. IPMI, iLO,
DRAC, etc.) to manage host power operations (on/off etc.) and querying current
power state in CloudStack.
Given the wide range of out-of-band management interfaces such as iLO and iDRA,
the service implementation allows for development of separate drivers as plugins.
This feature comes with a ipmitool based driver that uses the
ipmitool (http://linux.die.net/man/1/ipmitool) to communicate with any
out-of-band management interface that support IPMI 2.0.
This feature allows following common use-cases:
- Restarting stalled/failed hosts
- Powering off under-utilised hosts
- Powering on hosts for provisioning or to increase capacity
- Allowing system administrators to see the current power state of the host
For testing this feature `ipmisim` can be used:

As recently discussed on the dev list:
This sorts the domain lists based on their path.
Especially handy when having a lot of domains,
like in a public cloud.
Cherry-picked to 4.5 branch since commit exists in 4.4 and master branch.
(cherry picked from commit befa28251d)

-Split 'dictionary.jsp' into two files -> 'dictionary.jsp' and
'dictionary2.jsp' -- this is due to JSP file constraints as the
localization object is getting quite long
-Per change above, 'dictionary' object is now split into an additonal
'dictionary2' object, which is merged with the main dict object on page
load
-All new dictionary mappings should be added to 'dictionary2' now.

This is a feature to handle DNS entries by means of an external DNS Provider,
such as Bind. These entries include DNS domains and reverse domains, VM records
and reverse records.
For a complete description, please refer to the design document available at
https://cwiki.apache.org/confluence/display/CLOUDSTACK/Bind+and+PowerDNS+integration+by+Globo+DNSAPI
For the discussion about this feature on the dev mailing list, please refer to
http://markmail.org/thread/fvwf36hpxotiibka
Summary:
- new Network Service Provider called GloboDNS
- new Network Element to manage network domains and VM records (entries) on an external API
- new Network Resource to communicate with GloboDNS (open source)
- new API command to add DNS server
- new global option to determine if this provider should override VM entries on external DNS server
- changes in UI to include GloboDNS in Providers list
