Suggestions for improvement:

Add the remaining features

Additional information:

From 3.3: https://rhevm_url/api/capabilities
NOTE: This should be carefully reviewed for accuracy!!  Ideally, we should have Description tag for each Feature

Gluster Support: Support for Gluster Volumes and Bricks
POSIX-FS Storage Type: posixfs [needs verbiage]
Port Mirroring: for nics [needs verbiage]
Display Server Time: Displays current time on RHEVM server
Display Host Memory: Displays current memory on RHEVM server
Display Host Sockets: Number of host sockets displayed. 'cores' now show num of cores per socket --> total cores in host is: cores*sockets
Search - Case Sensitivity: Ability to specify whether a search query should ignore case, by providing a URL parameter
Max Results for GET Request: Ability to specify max number of results returned from a GET request
JSON Content-Type: Unknown [needs verbiage]
Correlation-Id: Enable setting Correlation-Id for POST and PUT commands, using a header.
Activate/Deactivate disk: Disk may be activated or deactivated (POST .../disks/{disk:id}/activate, POST .../disks/{disk:id}/deactivate
Activate/Deactivate NIC: NIC may be activated or deactivated (POST .../nics/{nic:id}/activate, POST .../nics/{nic:id}/deactivate
Snapshots Refactoring: Snapshot is no a point-of-time representation of a VM, including sublollections such as disks, nics, cdroms... [sic, needs editing]
Remove Template Disks From Specified Storage-Domain: Ability to remove template images from a specific storage-domain: DELETE .../api/templates/{template:id}/disks/{disk:id}, supplying <action><storage_domain id="xxx"</storage_domain></action> [needs editing]
Floating Disks: A disk may be attached to 0 VMs. Such a disk is 'floating'. Therefore disks now also appear in the root collection, no only under VM: .../api/disks. Attaching a disk to VM is done by adding a disk with an existing ID to the VM. Detaching a disk from a VM is done by deleting the Disk from the VM, supplying 'detach=true'
Async Delete: Ability to specify that DELETE request will be performed asynchronously, using the 'async' url parameter.
Session Based Authentication: Ability to maintain client-server session, to avoid login per request. Done by providing a header
VM Applications: List of Applications installed on a VM. VM Applications appear under VM: .../api/vms/xxx/applications.
VirtIO-SCSI Support: Support for paravirtualized SCSI controller device.
Custom comment in the resource: At this point added ability to add custom comment only to the datacenter, in future versions we may allow it in other resources as well.
Refresh Host Capabilities: Getting host data synchronized with getVdsCaps (GET .../hosts/{host:id};force
Memory Snapshot: Ability to save memory state as part of snapshot.
Watchdog Device: Ability to create watchdog devices in VM's
SSH Authentication Method: Ability to authenticate by SSH to host using privileged user password or SSH public key
Force Select SPM: Ability to force select a host as SPM
Console Device: Ability to control attaching of console devices in VM's
Storage server connections of a storage domain: Ability to view storage server connections of a specific storage domain (GET .../storagedomains/{storagedomain:id}/storageconnections)
Attach/Detach storage server connections (to/from a storage domain): Ability to attach/detach storage server connections to/from a specific storage domain (common use case: disaster recovery)
Single PCI for Qxl: Ability to view multiple video devices via single PCI guest device
Add VM from OVF configuration: Ability to add VM from provided OVF configuration.
Vnic Profiles: Configuring VM network interface by a profile (for network QoS, custom properties and port mirroring)
Image Storage Domains (Tech Preview): Importing and exporting images from and to image storage domain (as for example OpenStack glance)
Gluster Hooks management: Ability to manage gluster hooks in cluster
VM FQDN: Ability to report the fully qualified domain name (FQDN) of a Virtual Machine
Attaching Disk snapshot to a vm: Support for attaching a disk snapshot to a vm.
Cloud Init: Support for VM initialization with Cloud Init.
