This feature adds the ability to create a new instance from a VM backup for dummy, NAS and Veeam backup providers. It works even if the original instance used to create the backup was expunged or unmanaged. There are two parts to this functionality:
Saving all configuration details that the VM had at the time of taking the backup. And using them to create an instance from backup.
Enabling a user to expunge/unmanage an instance that has backups.
This PR allows attaching of GPU devices via PCI, mdev or VF to an Instance for KVM.
It allows the operator to discover the GPU devices on the KVM host and create a Compute Offering with GPU support based on the available GPU devices on the host. Once the operator has created the Compute offering, it can be used by users to launch Instances with GPU devices.
The Extensions Framework in Apache CloudStack is designed to provide a flexible and standardised mechanism for integrating external systems and custom workflows into CloudStack’s orchestration process. By defining structured hook points during key operations—such as virtual machine deployment, resource preparation, and lifecycle events—the framework allows administrators and developers to extend CloudStack’s behaviour without modifying its core codebase.
The Netris Plugin introduces Netris as a network service provider in CloudStack to be able to create and manage Virtual Private Clouds (VPCs) in CloudStack, being able to orchestrate the following network functionalities:
- Network segmentation with Netris-VXLAN isolation method
- Routing between "public" IP and network segments with an ACS ROUTED mode offering
- SourceNAT, DNAT, 1:1 NAT between "public" IP and network segments with an ACS NATTED mode offering
- Routing between VPC network segments (tiers in ACS nomenclature)
- Access Lists (ACLs) between VPC tiers and "public" network (TCP, UDP, ICMP) both as global egress rules and "public" IP specific ingress rules.
- ACLs between VPC network tiers (TCP, UDP, ICMP)
- External load balancing – between VPC network tiers and "public" IP
- Internal load balancing – between VPC network tiers
- CloudStack Virtual Router services (DHCP, DNS, UserData, Password Injection, etc…)
* Option to deploy a VM with existing volume/snapshot
* smoke test changes
check if the hypervisor is KVM
check if the primary storage's scope is ZONE wide
* skip all tests if the storage isn't Zone-Wide and the hypervisor isn't KVM
* support StorPool tags
add StorPool tags to a volume created from snapshot or to a volume which
will be attached as a ROOT to a new VM
* Add StorPool tags on the new ROOT volume
* Add the StorPool's tags when volume is created from a snapshot or a
volume is attached as a ROOT to a VM
* Addressed review
* Management Server - Prepare for Maintenance and Cancel Maintenance improvements:
- Added new setting 'management.server.maintenance.ignore.maintenance.hosts' to ignore hosts in maintenance states while preparing management server for maintenance. This skips agent transfer and agents count check for hosts in maintenance.
- Rebalance indirect agents after cancel maintenance, using rebalance parameter in cancelMaintenance API
- Force maintenance after maintenance window timeout, using forced parameter in prepareForMaintenance API.
- Propagate 'indirect.agent.lb.check.interval' setting change to the host agents.
* rebases fixes
* code improvements, cleanup
* [UI] Set rebalance true by default in cancel maintenance dialog
* Update MS state after executing cluster cmd in the target MS, and some code improvements
* code improvements
* Ensure the host lb algorithm 'shuffle' is applied once before disabling the indirect agent lb check background task
* [Vmware to KVM Migration] Display virt-v2v and ovftool versions for supported hosts for migration
* Fix UI display
* Address review comments
* Fix ovftool and version display - also display versions on host details view
* Introducing Storage Access Groups to define the host and storage pool connections
In CloudStack, when a primary storage is added at the Zone or Cluster scope, it is by default connected to all hosts within that scope. This default behavior can be refined using storage access groups, which allow operators to control and limit which hosts can access specific storage pools.
Storage access groups can be assigned to hosts, clusters, pods, zones, and primary storage pools. When a storage access group is set on a cluster/pod/zone, all hosts within that scope inherit the group. Connectivity between a host and a storage pool is then governed by whether they share the same storage access group.
A storage pool with a storage access group will connect only to hosts that have the same storage access group. A storage pool without a storage access group will connect to all hosts, including those with or without a storage access group.
Sometimes hypervisor hosts (direct agents) stuck with Disconnect state during agent rebalancing activity across multiple management server nodes. This issue was noticed during frequent restart of the management server nodes in the cluster.
When there are multiple management server nodes in a cluster, if one or more nodes are shutdown/start/restart, CloudStack will rebalance the hosts among the remaining nodes or move the nodes to the newly joined management server nodes. During the rebalancing period multiple operations could happen including:
- DirectAgentScan at interval of configured direct.agent.scan.interval
- AgentRebalanceScan to identify and schedule rebalance agents
- TransferAgentScan to transfer the host from original owner to future owner
**Current Rebalance behavior**
1. For hosts that have AgentAttache && not forForward but in Disconnect state, CloudStack simply ignore these hosts without trying to ping again or update the status of the host.
2. For hosts that have AgentAttache && forForward, CloudStack removes the agent but still try to loadDirectlyConnectedHost.
**Improved Rebalance behavior**
During DirectAgentScan: scanDirectAgentToLoad(), identify hosts that for self-managed hosts that are in Disconnect state (disconnected after pingtimeout).
1. For hosts that have AgentAttache and is forForward, CloudStack should remove the agent
2. For hosts that have AgentAttache and is not forForward but in Disconnect state, CloudStack should try to investigate and update the status to Up if host is pingable.
3. For hosts that don't have AgentAttache, CloudStack should try to loadDirectlyConnectedHost.
