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.
This feature allow admins to dedicate a range of public IP addresses to the SSVM and CPVM, such that they can be subject to specific external firewall rules. The option to dedicate a public IP range to the System VMs (SSVM & CPVM) is added to the createVlanIpRange API method and the UI.
Solution:
Global setting 'system.vm.public.ip.reservation.mode.strictness' is added to determine if the use of the system VM reservation is strict (when true) or preferred (false), false by default.
When a range has been dedicated to System VMs, CloudStack should apply IPs from that range to
the public interfaces of the CPVM and the SSVM depending on global setting's value:
If the global setting is set to false: then CloudStack will use any unused and unreserved public IP
addresses for system VMs only when the pool of reserved IPs has been exhausted
If the global setting is set to true: then CloudStack will fail to deploy the system VM when the pool
of reserved IPs has been exhausted, citing the lack of available IPs.
UI Changes
Under Infrastructure -> Zone -> Physical Network -> Public -> IP Ranges, button 'Account' label is refactored to 'Set reservation'.
When that button is clicked, dialog displayed is also refactored, including a new checkbox 'System VMs' which indicates if range should be dedicated for CPVM and SSVM, and a note indicating its usage.
When clicking on button for any created range, UI dialog displayed indicates whether IP range is dedicated for system vms or not.
This feature allows CloudStack administrators to create layer 2 networks on CloudStack. As these networks are purely layer 2, they don't require IP addresses or Virtual Router, only VLAN is necessary (provided by administrator or assigned by CloudStack). Also, network services should be handled externally, e.g. DNS, DHCP, as they are not provided by L2 networks.
As a consequence, a new Guest Network type is created within CloudStack: L2
Description:
Network offerings and networks support new guest type: L2.
L2 Network offering creation allows administrator to select Specify VLAN or let CloudStack assign it dynamically.
L2 Network creation allows administrator to specify VLAN tag (if network offerings allows it) or simply create network.
VM deployments on L2 networks:
VMs should not IP addresses or any network service
No Virtual Router deployed on network
If Specify VLAN = true for network offering, network gets implemented using a dynamically assigned VLAN
UI changes
A new button is added on Networks tab, available for admins, to allow L2 networks creation
* CLOUDSTACK-9972: Enhance listVolume API to include physical size and utilization.
Also fixed pool, cluster and pod info
* CLOUDSTACK-9972: Fix volume_view and duplicate API constant
* CLOUDSTACK-9972: Backport Do not allow vms to be deployed on hosts that are in disabled pod
* CLOUDSTACK-9972: Fix localization missing keys
* CLOUDSTACK-9972: Fix sql path
This feature allows changing permission for existing role permissions, as those were static and could not be changed once created. It also provides the ability to change these permissions in the UI using a drop down menu for each permission rule, in which admin can select ‘Allow’ or ‘Deny’ permission.
Changes in the API:
This feature modifies behaviour of updateRolePermission API method:
New optional parameters ‘ruleid’ and ‘permission’ are introduced, they are mutual exclusive to ‘ruleorder’ parameter. This defines two use cases:
Update role permission: ‘ruleid’ and ‘permission’ parameters needed
Update rules order: ‘ruleorder’ parameter needed
Parameter ‘ruleorder’ is now optional
updateRolePermission providing ‘ruleorder’ parameter should be sent via POST
This allows native CloudStack users to change password in UI when LDAP
is enabled. Overall changes:
- A new usersource returned in the listUsers response
- Removed ldap check in the UI, replaced with check based on user source
- DB changes to include user.source in user_view
- Changed UI error message for non-native users trying to change password
