In VMware during VM start the existing disk information is used to configure the VMs. So even if a new disk is created using the new template VM continues to use the old disk.
Once the old root disk is marked for destroy force expunge it and sync the new disk into the VM folder before VM start
Implemented commands that are required for VR to bootup and Vm deployment to work
Modified hyperv agent code, to deploy VR with Boot Args, boot args passed to VR using KVP Exchange Component.
Fix for VR to boot up and get configured with boot args, Fixed issue in VolumeOrchestrator
Implemented SetFirewallRulesCommand in HyperV Resource
Implemented VR network commands to provide the necessary services from VR
Fixed hyperv localstorage path encode url issue. encode is converting space to '+'
Cloudstack sends requests to directly managed HV hosts (direct agents) using the direct agent thread pool. The size of the pool is determined by global config direct.agent.pool.size defaulted to 500.
Currently there is no restriction on the number of threads a direct agent can use from this shared thread pool to send requests to the host. This is fine as long as the host is responding to requests
in a reasonable amount of time. But if there is a considerable delay in getting response, the thread remain blocked for that much time. As more commands are send to the slow host threads keep getting
blocked. This can eventually lead to a situation where requests to healthy hosts cannot be processed as there are not enough free threads.
The problem being addressed here is to localize the impact of few bad hosts, so that entire management server is not affected.
One such way is to throttle based on the # of outstanding requests on per host basis. The outstanding requests to a host will be a % of direct agent pool size. This is configurable based on
direct.agent.thread.cap. The default value is 0.1 or 10%, a value of 1 would mean the old behavior where there is no upper cap. This will ensure that the impacted host will be bound by a upper cap on the number of threads it can use to process requests and not the entire pool.

Introduction of a new Transaction API that is more consistent with the style
of Spring's transaction managment. The existing Transaction class was renamed
to TransactionLegacy. All of the non-DAO code in the management server has been
updated to use the new Transaction API.
was discussed on the mailing list as a useful debugging tool, currently
the log prints the DB id of the agent, which makes admins have to look
it up to know where the Command was run.
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.
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!

Issue happens as there are more than one thread processing connect for a host simultaneously. The VM full sync. is not designed to work in this scenario and as a result user VMs may get stopped incorrectly.
Direct agent scan task runs at regular intervals (direct.agent.scan.interval defaulted to 90 secs) and identifies hosts that needs to be processed for connect. In a normal scenario hosts mostly get connected within that interval and there are no issues. But if due to some reason the connect process takes more time and is not completed by the time next agent scan runs. In this case, based on the db. state same hosts may get picked up again. And then there will be situations where more than one thread is processing connect for the same host.
The fix is to check if there is a thread already processing connect for a host and in this case all subsequent threads for that host will simply bail out. Also there may be a scenario where one thread already completed processing connect but another thread already got scheduled before that and will again repeat the same. This is also prevented by putting appropriate checks.
