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.
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:
- 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"
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.
KVM - Create template from volume
Vmware - Create template from volume / Create template from snapshot
send the physical size in the copycommand which accordingly will populate template store ref and the usage_event tables with the right physical size

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.
Detail: Cloudstack tries to stop VMs all the time, for all sorts of reasons,
but usually just to get into a known state. Libvirt throws an exception of
'Domain not found' when attempting to stop a VM that doesn't exist. This causes
problems for troubleshooting real issues. Domain not found should equate
to success if trying to stop.
