These changes are a joint effort between Edison and I to refactor some
of the code around snapshotting VM volumes and creating
templates/volumes from VM volume snapshots. In general, we were working
towards allowing PrimaryDataStoreDrivers to create snapshots on primary
storage and not requiring the snapshots to be transferred to secondary
storage.
High level changes:
-Added uuid to NfsTO, SwiftTO & S3TO to cut down on the requirement of
PrimaryDataStoreTO and ImageStoreTO which don't really serve much of a
purpose
-Initial work towards enable reverting VM volume from snapshots
-Added hypervisor commands for introducing and forgetting new hypervisor
objects (snapshots, templates & volumes)

ACS is now comprised of a hierarchy of spring application contexts.
Each plugin can contribute configuration files to add to an existing
module or create it's own module.
Additionally, for the mgmt server, ACS custom AOP is no longer used
and instead we use Spring AOP to manage interceptors.
The managed context framework provides a simple way to add logic
to ACS at the various entry points of the system. As threads are
launched and ran listeners can be registered for onEntry or onLeave
of the managed context. This framework will be used specifically
to handle DB transaction checking and setting up the CallContext.
This framework is need to transition away from ACS custom AOP to
Spring AOP.
Various classes are using member injection to inject extensible objects.
Really those object should come from an AdapterList that is injected in.
This patch switches the code to use setter injection that will later allow
spring to inject an AdapterList or something similar to allow
extensibility.
DefaultUserAuthenticator maskes the _name varible in ComponentLifecycleBase
making the setName() method not work as expected. This patch cleans up the
code such that getName() will be getClass().getSimpleName() unless
overridden in the Spring configuration.
Initial patch for VXLAN support.
Fully functional, hopefully, for GuestNetwork - AdvancedZone.
Patch Note:
in cloudstack-server
- Add isolation method VXLAN
- Add VxlanGuestNetworkGuru as plugin for VXLAN isolation
- Modify NetworkServiceImpl to handle extended vNet range for VXLAN isolation
- Add VXLAN isolation option in zoneWizard UI
in cloudstack-agent (kvm)
- Add modifyvxlan.sh script that handle bridge/vxlan interface manipulation script
-- Usage is exactly same to modifyvlan.sh
- BridgeVifDriver will call modifyvxlan.sh instead of modifyvlan.sh when VXLAN is used for isolation
Database changes:
- No change in database structure.
- VXLAN isolation uses same tables that VLAN uses to store vNet allocation status.
Known Issue and/or TODO:
- Some resource still says 'VLAN' in log even if VXLAN is used
- in UI, "Network - GuestNetworks" dosen't display VNI
-- VLAN ID field displays "N/A"
- Documentation!

Libvirt reports:
org.libvirt.LibvirtException: Storage volume not found: no storage vol
with matching name
in some cases, if the volume is created on one kvm host, while accessed
from other host.
It's possible due to concurrent access(read/write) storage.
The current fix is to try serveral times, and wait for 30 seconds for
each retry.
If the issue still there, then need to sync the storage pool access

There still exist two issues after Edison's commits.
(1) Migration from new hosts to old hosts failed.
The bridge name on old host is set to cloudVirBr* if network.bridge.name.schema is set to 3.0 in /etc/cloudstack/agent/agent.properties, but the actual bridge name is breth*-* after running cloudstack-agent-upgrade.
(2) all ports of vms (Basic zone, or Advanced zone with security groups) on old hosts are open, because the iptables rules are binding to device (bridge) name which is changed by cloudstack-agent-upgrade.
After this, the KVM upgrade steps :
a. Install 4.2 cloudstack agent on each kvm host
b. Run "cloudstack-agent-upgrade". This script will upgrade all the existing bridge name to new bridge name, and update related firewall rules.
c. install a libvirt hook:
c1. mkdir /etc/libvirt/hooks
c2. cp /usr/share/cloudstack-agent/lib/libvirtqemuhook /etc/libvirt/hooks/qemu
c3. chmod +x /etc/libvirt/hooks/qemu
c4. service libvirtd restart
c5. service cloudstack-agent restart

The migrate method from libvirt supports passing down a different XML for running
the instance of the target hypervisor.
This enables the VNC to bind to the private IP Address of the hypervisor and during
migration this will be changed to the private IP address of the target host.
This way VNC doesn't listen world wide and is much safer.
It was implemented by extending the NFS provider. Its validation was updated so that you can pass it a URL containing the
details of a CIFS share. The code that mounts NFS shares was extended to allow it do the same for CIFS shares. Otherwise,
the secondary storage code is left unchanged.
A recent code change in NetworkManager causes NullPointerExceptions when DHCP
capability list is null.
The commit which made the NetworkManager change also changed the VirtualRouter
to not use null for the capabilitylist, but didn't make this change for other
network devices, causing DHCP to fail on MidoNet.
This change also updates the MidoNet plugin to use the most recent MidoNet API.
Changes:
createZone API:
- This API takes in domainid, set it to the zone record in the data_center table
updateZone API:
- This API uses 'isPublic' flag to set a private zone to public - if this flag is set and the zone is dedicated, release the dedication and remove the domainid from the data_center table
listZone API:
- This API already has 'domainid' parameter. We should allow list zones by domain for Root admin.
DedicateZone API:
- set domainid in the data_center table
ReleaseDedicatedZone API:
- remove zoneid from the data_center table
Changes:
- Adding mocks in unit tests for new injected components
Conflicts:
server/test/org/apache/cloudstack/networkoffering/ChildTestConfiguration.java
Changes:
- Implict creation of the 'ExplicitDedication' Affinity group during resource dedication
- Only one group per account or per domain will be present
- ListDedicatedResources by affinityGroup
- Deployment should consider dedicated resources associated to the group only
- Deleting affinity group should release the dedicated resouces
- Releasing the dedicated resources should remove the group associated if there are no more resources.

Changes:
- 'ExcplicitDedication' type of group can be created/deleted by Root admin only
- Users can no longer create this type of affinity group
- RootAdmin can create this type of affinitygroup at domain level. Such a domain level group is available for all accounts in that domain for listing and for use during deployVM.
- The domain level affinitygroup should be visible to the users in that domain, domain admins and Root admin.

This failed due to a RAW -> QCOW2 conversion (again).
The current code still makes to much assumptions about everything always
being QCOW2 while that is not always true.

If all the VM's volumes are on zone wide primary storage pool then live migration of the VM would not involve storage migration. Hence MigrateVM API would be called against MigrateVMWithVolume. So far PrepareForMigrationCommand handled scenarios of VM moving across hosts within a cluster, but with zone wide primary storage in picture this command need to handle scenarios of VM moving across clusters. Try to find the VM in datacenter if not found within cluster.

Although libvirt supports resizing RBD volumes (and other formats) the
Java bindings (libvirt-java) don't.
Right now we use the Java bindings for librbd to handle the resizing for us,
but in the future this should be done by libvirt rather then these
Java bindings.
