This feature allows using templates and ISOs avoiding secondary storage as intermediate cache on KVM. The virtual machine deployment process is enhanced to supported bypassed registered templates and ISOs, delegating the work of downloading them to primary storage to the KVM agent instead of the SSVM agent.
Template and ISO registration:
- When hypervisor is KVM, a checkbox is displayed with 'Direct Download' label.
- API methods registerTemplate and registerISO are both extended with this new parameter directdownload.
- On template or ISO registration, no download job is sent to SSVM agent, CloudStack would only persist an entry on template_store_ref indicating that template or ISO has been marked as 'Direct Download' (bypassing Secondary Storage). These entries are persisted as:
template_id = Template or ISO id on vm_template table
store_id NULL
download_state = BYPASSED
state = Ready
(Note: these entries allow users to deploy virtual machine from registered templates or ISOs)
- An URL validation command is sent to a random KVM host to check if template/ISO location can be reached. Metalink are also supported by this feature. In case of a metalink, it is fetched and URL check is performed on each of its URLs.
- Checksum should be provided as indicated on #2246: {ALGORITHM}CHKSUMHASH
- After template or ISO is registered, it would be displayed in the UI
Virtual machine deployment:
When a 'Direct Download' template is selected for deployment, CloudStack would delegate template downloading to destination storage pool via destination host by a new pluggable download manager.
Download manager would handle template downloading depending on URL protocol. In case of HTTP, request headers can be set by the user via vm_template_details. Those details should be persisted as:
Key: HTTP_HEADER
Value: HEADERNAME:HEADERVALUE
In case of HTTPS, a new API method is added uploadTemplateDirectDownloadCertificate to allow user importing a client certificate into all KVM hosts' keystore before deployment.
After template or ISO is downloaded to primary storage, usual entry would be persisted on template_spool_ref indicating the mapping between template/ISO and storage pool.
Steps to reproduce issue
Deploy a VM
Take snapshot of the root volume
Delete the snapshot
Before the garbage collector has run, shutdown the VM and assign the VM to other user.
When garage collector executes NPE shows in the logs.
This happens when the root disk size is overridden. The primary storage limit check should be performed based on overridden size instead of template size. Enabled root disk resize tests to run on simulator as well.
* Cleanup and Improve NetUtils
This class had many unused methods, inconsistent names and redundant code.
This commit cleans up code, renames a few methods and constants.
The global/account setting 'api.allowed.source.cidr.list' is set
to 0.0.0.0/0,::/0 by default preserve the current behavior and thus
allow API calls for accounts from all IPv4 and IPv6 subnets.
Users can set it to a comma-separated list of IPv4/IPv6 subnets to
restrict API calls for Admin accounts to certain parts of their network(s).
This is to improve Security. Should an attacker steal the Access/Secret key
of an account he/she still needs to be in a subnet from where accounts are
allowed to perform API calls.
This is a good security measure for APIs which are connected to the public internet.

Allow security policies to apply on port groups:
- Accepts security policies while creating network offering
- Deployed network will have security policies from the network offering
applied on the port group (in vmware environment)
- Global settings as fallback when security policies are not defined for a network
offering
- Default promiscuous mode security policy set to REJECT as it's the default
for standard/default vswitch
Portgroup vlan-trunking options for dvswitch: This allows admins to define
a network with comma separated vlan id and vlan
range such as vlan://200-400,21,30-50 and use the provided vlan range to
configure vlan-trunking for a portgroup in dvswitch based environment.
VLAN overlap checks are performed for:
- isolated network against existing shared and isolated networks
- dedicated vlan ranges for the physical/public network for the zone
- shared network against existing isolated network
Allow shared networks to bypass vlan overlap checks: This allows admins
to create shared networks with a `bypassvlanoverlapcheck` API flag
which when set to 'true' will create a shared network without
performing vlan overlap checks against isolated network and against
the vlans allocated to the datacenter's physical network (vlan ranges).
Notes:
- No vlan-range overlap checks are performed when creating shared networks
- Multiple vlan id/ranges should include the vlan:// scheme prefix

Fix: Block VMOperations if Host in PrepareForMaintenance mode. VM operations (Stop, Reboot, Destroy, Migrate to host) are not allowed when Host in PrepareForMaintenance mode.
Added ability to specify mac in deployVirtualMachine and
addNicToVirtualMachine api endpoints.
Validates mac address to be in the form of:
aa:bb:cc:dd:ee:ff , aa-bb-cc-dd-ee-ff , or aa.bb.cc.dd.ee.ff.
Ensures that mac address is a Unicast mac.
Ensures that the mac address is not already allocated for the
specified network.
given is running out of capacity. If host id is specified the deployment should happen
on the given host and it should fail if the host is out of capacity. We are retrying
deployment on the entire zone without the given host id if we fail once. The retry,
which will retry on other hosts, should only be attempted if host id isn't given.
Also, introduces global setting

CLOUDSTACK-8841: Storage XenMotion from XS 6.2 to XS 6.5 fails.Removed Host version check in API. Because
Case 1:(Lower to Higher Version)
Migration from lower version to higher version is valid.
Case 2:(Higher to Lower Version)
In this case system(Host) will not allow.
So no need to check version in API. Additionally, CLOUDSTACK User Interface(UI) does not allow migration between different version of hyper-visors. But sometimes user wants to do migration from Lower to Higher Version. Now he can do it via API.

CLOUDSTACK-9738: [Vmware] Optimize vm expunge process for instances with vm snapshots## Description
It was noticed that expunging instances with many vm snapshots took a look of time, as hypervisor received as many tasks as vm snapshots instance had, apart from the delete vm task. We propose a way to optimize this process for instances with vm snapshots by sending only one delete task to hypervisor, which will delete vm and its snapshots
## Use cases
1. deleteVMsnapohsot-> no changes to current behavior
2. destroyVM with expunge=false -> no actions to VMsnaphsot is performed at the moment. When VM cleanup thread is executed it will perform the same sequence as (3). If instance is recovered before expunged by the cleanup thread it will remain intact with VMSnapshot chain present
3. destroyVM with expunge=true:
* Vmsnaphsot is marked with removed timestamp and state = Expunging in DB
* VM is deleted in HW
* pr/1905:

(1) add support to create/delete/revert vm snapshots on running vms with QCOW2 format
(2) add new API to create volume snapshot from vm snapshot
(3) delete metadata of vm snapshots before stopping/migrating and recover vm snapshots after starting/migrating
(4) enable deleting of VM snapshot on stopped vm or vm snapshot is not listed in qcow2 image.
(5) enable smoke tests for vmsnaphsots on KVM
Introduced a global configuration flag 'cluster.threshold.enabled'. By default the flag is true.
If the value is false, then a VM can be started in a cluster even if the cluster thresholds are
crossed. However, for a new VM deployment the cluster threshold will always be honoured.
