VM live migration
* Add revoke certificates API
* Add background task to sync certificates
* Fix marvin test and revoke certificate
* Fix certificate sent to hypervisor was missing headers
* Fix background task for uploading certificates to hosts
Currently an admin can choose which host a VM is to be started on.
They should be able to 'override' the allocation algorthm to a greater
or lesser extent at will, and be able to choose the pod, cluster or host
that they wish a new VM to be deployed in.
DeployVirtualMachine API has been extended with additional, optional
parameters podid and clusterid that will be passed to and used in the
deployment planner, when selecting a viable host. If the user supplies
a pod, a suitable host in the given pod will be selected. If the user
supplies a cluster, a suitable host in the given cluster will be selected.
Based on the parameter supplied and on passing validation, the VM will
then be deployed on the selected host, cluster or pod.
If there are many projects and accounts, listing projects/accounts will take long time getting the resource limitation and resource count in the process. However resource count/limitation are not needed sometimes.
Add an option 'details' to listProjects and listAccounts. If you do not need the resource count/limitation, please add details=min to api call. The api execution time will be reduced significantly.
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

* Improvements on upload direct download certificates
* Move upload direct download certificate logic to KVM plugin
* Extend unit test certificate expiration days
* Add marvin tests and command to revoke certificates
* Review comments
* Do not include revoke certificates API
See #3339: a runtime exception is thrown but it should be converted to an error return. Wrapping it in a CloudRuntimeException should do the trick.

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.

Fixes intermittent failures:
- Add a pause to avoid tests restarting before VRs recovering from HA have fully booted.
- Add some pauses to allow services to restart and hosts to reconnect before continuing tests.
- Adding a loop around this method because sometimes VRs are overloaded and just respond with exception, so it'll catch it and try 5 times with 30sec cooldown. If that fails as well it'll fail the test.
- wait until host is up using explicit check
* 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
* CLOUDSTACK-4045 added a check for network state when determining whether a new IP should be source NAT. this prevents associated IP's to be marked as source NAT when the network is in allocated state, causing disassociateIpAddress to fail later
* Remove mock object that cause other tests to fail
* Remove underscores from variable types and add documentation for the created method
* Improve exception message to include network name
* Include network UUID with the Exception message and fix failing marvin test
* Rebase against latest master and format AssociateIPAddrCmd class

The view "service_offering_view" doesn't include removed SOs, as a result when SO is removed, the bug happens. The PR introduces a change for resource calculation changing "service_offering_view" to "service_offering" table which has all service offerings.
Must be fixed in:
4.12
4.11
Fixes: #3009
