qemu-img 10.1.0 changed the "qemu-img --help" supported-formats header
from "Supported formats:" to "Supported image formats:". The regex in
QemuImg.helpSupportsImageFormat() only matched the old header, so
hostSupportsVolumeEncryption() returned false on affected hosts even
though cryptsetup and the luks format were both available, blocking
encrypted offerings.
Make the "image" keyword optional in the regex so it matches both the
legacy and current qemu-img help output.

* KVM: add configurable MAC/IP script hook for static ARP/NDP and routes
Introduces a new agent.properties option `vm.network.macip.static`
(false by default) that makes BridgeVifDriver invoke on modifymacip.sh
on every NIC plug (VM start) and unplug (VM stop).
This is very useful in EVPN+VXLAN environments as it can reduce BUM
traffic. By setting static ARP/NDP entries bridges can be configured
using 'neigh_suppress on' as the ARP/NDP entries are already set
statically by CloudStack.
Setting 'neigh_suppress on' requires a manual change in the modifyvxlan.sh
script as this is not the default behavior.
* vxlan: In EVPN mode, disable ARP/NDP learning
FRR populates the FDB via BGP EVPN, so kernel data-plane learning is
redundant and counterproductive.
Static ARP (IPv4) and NDP (IPv6) entries are added on startup of the
Instance and remove on shutdown.
FRR populates the FDB/neighbor table via control plane, and neigh_suppress
tells the kernel bridge to use that information instead of flooding.
This will vastly reduce BUM traffic with static ARP/NDP entries.
* Add xenserver.create.full.clone global setting
Adds a StoragePool-scoped boolean ConfigKey mirroring vmware.create.full.clone
so XenServer-backed VMs can be deployed as full VDI copies (VDI.copy) instead
of always using linked clones (VDI.clone). Default false preserves today's
behavior.
The per-pool flag flows into the existing PrimaryDataStoreTO.fullCloneFlag
through a new dispatch method addFullCloneAndDiskprovisiongStrictnessFlagOnDest
that switches on hypervisor type.
* Fix HypervisorType dispatch in addFullClone flag helper
Replace invalid switch on Hypervisor.HypervisorType (not a Java enum) with
equality checks so cloud-engine-storage-datamotion compiles.

Implements incremental backup support for the NAS backup provider on KVM, using QEMU dirty bitmaps and libvirt's backup-begin API. RFC: apache/cloudstack#12899.
For large VMs this reduces daily backup storage 80–95% and shortens backup windows from hours to minutes (e.g. a 500 GB VM with moderate writes goes from ~500 GB/day to ~5–15 GB/day after the initial full backup).

* kvm: Add a configuration setting to switch between multicast and evpn VXLAN modes
Using the 'network.vxlan.mode' setting you can switch between the multicast (default) and evpn VXLAN modes on a KVM Agent.
When nothing is configured CloudStack will default to multicast by using the modifyvxlan.sh script in the background.
If this setting is set to 'evpn' the KVM Agent will execute the 'modifyvxlan-evpn.sh' script which will configure the VXLAN
devices for EVPN (usually with FRRouting with BGP) mode.
This removes the need to manually replace a shell script on the hypervisor to switch modes.
Existing environments are not touched by this and it is safe to add this setting a an environment already using EVPN for the
VXLAN deployment.
* Add network.vxlan.mode to agent.properties
Make sure there is an example in the agent.properties file so people
can easily discover this configuration setting exists

This PR enhances the existing CLVM implementation which was based on the deprecated CLVM technology which was based on corosync/pacemaker. With RHEL 7 having reached EOL, CLVM seems to be broken. CLVM supports RAW volumes on LVM , where as CLVM_NG support QCOW2 on LVM.
Further details: https://cwiki.apache.org/confluence/display/CLOUDSTACK/Modernized+CLVM%3A+Enhancements+and+CLVM_NG+support
NOTE: On testing - it was identified that incremental snapshots for clvm-ng do not work as expected. As of now it's been removed from scope. So, CLVM and CLVM_NG would only support full snapshots.
* add support for proper cleanup of snapshots and prevent vol snapshot of running vm
* remove snap vol restriction for sunning vms
* refactor clvm code
* add support for live migration
* add support for migrating lvm lock
* clvm deletion called explicitly
* made necessary changes to allow migration of lock and deletion of detached volumes
* fix create vol from snap and attach
* add support to revert snapshot for clvm
* add support to revert snapshot for clvm
* make zero fill configurable

2. handle attaching volumes to stopped VMs \n
3. Handle lock transfer when VM is started on another host

* evist lock tracking - use lvs command to get lock host than DB
* add test for pre/post migration
* Create a CLVM storage adaptor
* update existing clvm get stats method

* improve lock host retrieval logic and quicker retrival using db host as first check point and then fanning out
* add proper support for resizing of clvm_ng which calculated PE correctly for qcow2 metadata
* fallback to full snapshots for clvm-ng - incremental not supported in 4.23
* expunge volume detail of lock host on vm expunge
* if vmmigration with volume is done to the same clvm volume group, then dont do data transfer, just lock transfer and vm
* add clvm pools with deterministic uuid , so as to prevent adding the same pool twic
* added a small improvement to factor in a senario when lv is inactive on all hosts, could happen in storage outage issue
* address comment - extract common code for endpoint identification if clvm pool type
* Address comments - add early return guard to reduce indentation
* minor improvement - when migrating vm with volumes, if there's a failures, change the clvm vols to exclusive on source from shared, and on success, change dest vol to exclusive only for cross-pool migration
* cleanup unused code and tests for incremental snaps for clvmng and other cleanups
* allow storage browser to list lv in clvm, fix clvm shrink, overprovisioning factor isnt used for clvm pools - so set it to 1 and prevented display of provisioning type for clvm
* no need to have locktransfercommand to execute in sequence
* increase lv cmd timeouts to consider cluster load

This PR introduces the initial implementation of Veeam integration support for KVM in CloudStack by adding a UHAPI-compatible server and image server components.
Veeam Backup & Replication interacts with virtualization platforms using its Universal Hypervisor API (UHAPI). To enable backup and restore workflows for CloudStack-managed KVM environments, this change introduces a UHAPI server that exposes CloudStack resources through a UHAPI-compatible interface.
In addition to the control plane APIs, an image server component is introduced to handle the data transfer operations required during backup and restore workflows.
The integration consists of two main components:
1. UHAPI Server (Control Plane) named CloudStack Veeam Control Service
A lightweight UHAPI server runs inside the CloudStack management server and exposes endpoints under:
/ovirt-engine
- /api - For APIs
- /sso - For authentication
- /services/pki-resource - For certificates
This server provides inventory discovery APIs required by Veeam and translates CloudStack resources into the structures expected by UHAPI.
The server:
- exposes infrastructure inventory
- handles authentication and session tokens
- maps CloudStack resources to UHAPI-compatible representations
2. Image Server (Data Plane) named CloudStack Image Service
A separate image server component is introduced to handle backup and restore data transfer operations.
This component:
- serves disk image data during backup
- receives image data during restore operations
- exposes endpoints used by Veeam worker components
- integrates with CloudStack storage to read and write VM disk data
The separation between both these components server ensures that:
- metadata APIs and control operations remain lightweight
- bulk image transfer operations are handled independently
