Add executeInVR() with timeout interface to VirtualRouterDeployer
AggregationControlCommand with Action.Finish may take longer than normal command
since it would execute all the commands in one execution, and it may result in
SSH timeout for SshHelper or other mechanism communicate with VR.
Introduce an new executeInVR() interface with added timeout period for waiting
FinishAggregationCommand to complete execution.

introduces capability to build a physical toplogy representation of a
VPC. This json file is encapsulated in
OvsVpcPhysicalTopologyConfigCommand, and is used to send full topology
to hypervisor hosts. On hypervisor this json config can be used to setup
tunnels, configure bridge, add flow rules etc

2) Corrected some logging in MidoNetPublicNetworkGuru - removed .toString method call on the objects in the log body as toString is called on the object by default when use log4j
With VirtIO enabled on KVM. FreeBSD 10 supports VirtIO for both the
network and the disks. This frees us from IDE and E1000 which should
also improve performance.
By default all network disks are in RAW format. Gluster works fine with
QCOW2 which has some advantages.
Disks are by default in QCOW2 format. It is possible to run into
a mismatch, where the disk is in QCOW2 format, but QEMU gets started
with format=raw. This causes the virtual machines to lockup on boot.
Failures to start a virtual machine can be verified by checking the log
of the virtual machine, and compare the output of 'qemu-img info'.
In /var/log/libvirt/qemu/<VM>.log find the URL for the drive:
-drive file=gluster+tcp://...,format=raw,..
Compare this with the 'qemu-img info' output of the same file, mounted
under /mnt/<pool-uuid>/<img-uuid>:
# qemu-img info /mnt/<pool-uuid>/<img-uuid>
...
file format: qcow2
...
This change makes passes the format when creating a disk located on RBD
(RAW only) and Gluster (QCOW2).

The support for Gluster as Primary Storage is mostly based on the
implementation for NFS. Like NFS, libvirt can address a Gluster environment
through the 'netfs' pool-type.
PrepareForMigrationCommand, so that destination hypervisor can
mount pool. This further exposed an issue for KVM where iso
was not getting cleaned up upon successful migration, fixed as well.
By default only the Integers between -128..127 are cached (unless overridden by java.lang.Integer.IntegerCache.high system property)
If the inbound or outbound values are higher, the reference comparison won't work.

This saves us a lot of code and libvirt is probably a better
place to do this.
libvirt-java now has the support we want, so we can now resize volumes
with libvirt.
(C)LVM volumes can't be resized using libvirt, so we have to
invoke a resize script for that.
By default the client_mount_timeout setting in librados is 300 seconds,
but that causes the connect to the Ceph cluster to block for 5 minutes
if the Ceph cluster is not available.
This patch is not ideal, but it mitigates the problem for now.
At a later point all this librados/librbd code should go back to libvirt
again, but the current versions of libvirt in the distributions are
to old for all the features we require.
For now this should prevent the CloudStack agent blocking for 5 minutes
when the Ceph cluster isn't available.
This is also tracked at the Ceph tracker: http://tracker.ceph.com/issues/6507
brought back up after being down for few hours,snapshot jobs do not get
triggered with reason "there is other active snapshot tasks on the
instance to which the volume is attached".
- the result of dividing long with long resulted in loss of precision both for network and IO

1) vxlan will use bridge scheme 'brvx-<vni>'. Multiple physical networks can host guest
traffic type with vxlan isolation, so long as they don't use the same VNI range.
2) Guest traffic labels can be physical interface if bridge by given name is not found.
Normally we take traffic label name, find the matching bridge, then resolve that to a
physical interface. Then we create guest bridges on that interface. Now we can just
specify the interface.

this patch tracks PV driver versions in vm details and template details.

Detail: Checks for other Ethernet interface names uses startsWith(),
whereas the p1p1 style interface uses a regex that doesn't allow for
tailing characters, and so blocks vlan IDs. Fixed.

I don't think host kernel version has any bearing on it. Original code
was tested with CentOS 6.3 and 6.4, but it seems to succeed or fail per-host,
e.g. a fast host might work and a slow host might not. I was getting intermittent
failures with ubuntu 12.04.3 prior to this patch.
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.
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.

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.

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.
