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
This is the output of the program, the developer documentation may be a better place

When developing against the CloudStack Orchestration Platform, you must following the following rules:
API Rule: Always be prepared to handle RuntimeExceptions.
When writing APIs, you must follow these rules:
API Rule: You may think you're the greatest developer in the world but every change to the API must be reviewed and approved.
API Rule: Every API must have unit tests written against it. And not it's unit tests
API Rule:

used cpu is getting bumped up when the over provisioning factor > 1. This was because we didnt record the overprovisioning factors of the vms which got deployed pre 4.2
Upgrade path will fix that by populating the cpu/mem overprovisioning factors for each of the vms in user_vm_details table using the global overprovisioning factor.

If the VM has snapshots then the chain_info of a volume can be longer than 255 characters.
Increasing the column length of chain_info in VolumeVO to match the maximum length of type text(db schema type)
Changes:
- Consider if VM requires the local storage or shared storage or both for its disks.
- Accordingly all pools in the cluster should consider local or shared or both pools

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.
