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.
* 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.

Sonarcube is great, but has no context and can be wrong, in this
case File.separator is nice if you're running platform independent,
the agent on OVM3 is however NOT platform independent and will break
if we feed it windows separators.
This is a plugin that puts in ovm3 support ranging from 3.3.1 to 3.3.2. Basic
functionality is in here, advanced networking etc..
Snapshots only work when a VM is stopped now due to the semantics of OVM's raw
image implementation (so snapshots should work on a storage level underneath the
hypervisor shrug)
This closes#113
