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
Reboot host

* Fix XenServer Security Groups 'vmops' script
- fix tokens = line.split(':') to tokens = line.split(';')
- fix expected tokens size from 5 to 4
- enhance logs
- remove unused vmops script. The XCP patch points to the vmops script
on the parent folder [1]. Thus, all XenServer versions are considering
the vmops script located at [2].
- fix UI ipv4/ipv6 cidr validator to allow a list of cidirs.
Fixing issue: #3192 Security Group rules not applied at all for
XenServer 6.5 / Advanced Zone
https://github.com/apache/cloudstack/issues/3192
* Update security group rules after VM migration
Add security group rules on target host
Cause: vmops script expected secondary IPs as "0;" but received "0:"
Remove security group network rules on source host.
Cause: destroy_network_rules_for_vm function on vmops script was not
called when migrating VM
* Add unit tests and address reviewers
* feature: add libvirt / qemu io bursting
Adds the ability to set bursting features from libvirt / qemu
This allows you to utilize the iops and bytes temporary "burst" mode
introduced with libvirt 2.4 and improved upon with libvirt 2.6.

* updates per rafael et al
* - Offline VM and Volume migration on Vmware hypervisor hosts
- Also add VM disk consolidation call on successful VM migrations
* Fix indentation of marvin test file and reformat against PEP8
* * Fix few comment typos
* Refactor debug messages to use String.format() when debug log level is enabled.
* Send list of commands returned by hypervisor Guru instead of explicitly selecting the first one
* Fix unhandled NPE during VM migration
* Revert back to distinct event descriptions for VM to host or storage pool migration
* Reformat test_primary_storage file against PEP-8 and Remove unused imports
* Revert back the deprecation messages in the custom StringUtils class to favour the use of the ApacheUtils
* Add Support for InfluxDB on StatsCollector
* Code refactored to fit Inner Class architecture.
Due to the inner class structure, test case for some methods will not be
implemented. On the future it will be necessary to refactor the whole
StatsCOllector architecture and extract inner classes.
Each Inner Class that is a "stats collector" and sends data to Influx
will extend AbstractStatsCollector to send metrics to the correct
measure ("table"). For instance, HostCollector sends data to host_stats,
VmStatsCollector sends data to vm_stats.
Add ping test for ensure that the target InfluxDB host is reachable
* Address PR reviews
* Enhance and tests implemented addressing reviewers.
* Set variables to private
* Allow KVM VM live migration with ROOT volume on file
* Allow KVM VM live migration with ROOT volume on file
- Add JUnit tests
* Address reviewers and change some variable names to ease future
implementation (developers can easily guess the name and use
autocomplete)
* Remove some unused Classes
These classes were deleted because they have no references in our code base. They are not in Spring execution flow nor instantiated with "new":
- com.cloud.agent.api.CheckStateAnswer
- com.cloud.agent.api.StartupVMMAgentCommand
- com.cloud.agent.api.routing.UserDataCommand
- remove from description at
com.cloud.configuration.Config.ExecuteInSequenceNetworkElementCommands
enum
- com.cloud.agent.api.storage.UpgradeDiskCommand
- com.cloud.agent.api.storage.CreatePrivateTemplateCommand
- com.cloud.agent.api.storage.DestroyAnswer
- Note: "FIXME: Should have an DestroyAnswer" at
com.cloud.storage.resource.StoragePoolResource
- com.cloud.agent.api.storage.UpgradeDiskAnswer
- com.cloud.agent.api.storage.ManageVolumeAvailabilityAnswer
- com.cloud.agent.api.storage.ManageVolumeAvailabilityCommand
- com.cloud.exception.UsageServerException
- com.cloud.info.SecStorageVmLoadInfo
- com.cloud.serializer.SerializerHelper
* PR#1448 update description of 'execute.in.sequence.network.element.commands' param
Update description of 'execute.in.sequence.network.element.commands'parameter to reflect an unused command that has been removed. The removed class command is 'UserDataCommand'.
* Add cloud schema to update SQL
These boolean-return methods are named as "getXXX".
Other boolean-return methods are named as "isXXX".
Considering there methods will return boolean values, it should be more clear and consistent to rename them as "isXXX".
(rebase #2602 and #2816)
This is a new feature for CS that allows Admin users improved
troubleshooting of network issues in CloudStack hosted networks.
Description: For troubleshooting purposes, CloudStack administrators may wish to execute network utility commands remotely on system VMs, or request system VMs to ping/traceroute/arping to specific addresses over specific interfaces. An API command to provide such functionalities is being developed without altering any existing APIs. The targeted system VMs for this feature are the Virtual Router (VR), Secondary Storage VM (SSVM) and the Console Proxy VM (CPVM).

This fixes move refactoring error introduced in #2283
For instance, the class DatadiskTO is supposed to be in com.cloud.agent.api.to package. However, the folder structure it was placed in is com.cloud.agent.api.api.to.
Skip tests for cloud-plugin-hypervisor-ovm3:
For some unknown reason, there are quite a lot of broken test cases for cloud-plugin-hypervisor-ovm3. They might have appeared after some dependency upgrade and was overlooked by the person updating them. I checked them to see if they could be fixed, but these tests are not developed in a clear and clean manner. On top of that, we do not see (at least I) people using OVM3-hypervisor with ACS. Therefore, I decided to skip them.
Identention corrected to use spaces instead of tabs in XML files
Remove maven standard module (which only a few were using) and get ride of maven customization for the projects structure.
- moved all directories to src/main/java, src/main/resources, src/main/scripts, src/test/java, src/test/resources
- grep scan to search for src/com and src/org left over
- grep for <project>/scripts to fix pom.xml configuration
- remove custom <build> configuration in pom.xml
