- New attribute VIDEO, that includes
- TYPE: Custom video device (none, vga, cirrus, virtio)
 - IOMMU: Enable IOMMU for the video device
 - ATS: Enable ATS (Address Translation Services) for the video device
 - VRAM: VRAM allocated to the video device (Megabytes)
 - RESOLUTION: Video resolution, in format like: 1280x720 or 1920x1080
- Support for onevm CLI command
- Updated VM xsd file.
- EXTERNAL_VM_ATTR can be defined in sched conf to add additional
VM attributes to the JSON document sent to the external sched. The
format is: "XPATH<:NAME>" (NAME is optional, if not defined the
original attribute name will be used).
- Add example server to the share folder
The connection to an external scheduler module is configured in sched.conf:
EXTERNAL_SCHEDULER = [
SERVER = "http://localhost:4567",
PROXY = "",
TIMEOUT = 10
]
The API post on '/' the list of VMs, their pre-selected list of
candidate hosts based on REQUIREMENTS along with the VM information
(CAPACITY, TEMPLATE and USER_TEMPLATE).
Example:
{
"VMS": [
{
"CAPACITY": {
"CPU": 1.5,
"DISK_SIZE": 1024,
"MEMORY": 131072
},
"HOST_IDS": [
3,
4,
5
],
"ID": 32,
"STATE": "PENDING",
"TEMPLATE": {
"AUTOMATIC_DS_REQUIREMENTS": "(\"CLUSTERS/ID\" @> 0)",
"AUTOMATIC_NIC_REQUIREMENTS": "(\"CLUSTERS/ID\" @> 0)",
"AUTOMATIC_REQUIREMENTS": "(CLUSTER_ID = 0) & !(PUBLIC_CLOUD = YES) & !(PIN_POLICY = PINNED)",
"CPU": "1.5",
"MEMORY": "128",
...
},
"USER_TEMPLATE": {}
},
{
"CAPACITY": {
"CPU": 1.5,
"DISK_SIZE": 1024,
"MEMORY": 131072
},
"HOST_IDS": [
3,
4,
5
],
"ID": 33,
"STATE": "PENDING",
"TEMPLATE": {
...
},
"USER_TEMPLATE": {}
}
]
}
The scheduler needs to respond to this post action with a simple list of
the allocation for each VM:
{
"VMS": [
{
"ID": 32,
"HOST_ID": 2
},
{
"ID": 33,
"HOST_ID": 0
}
]
}
This commits vendorize Vendorize nlohmann-json (MIT license)
Includes the following changes:
- xml-schema for Backup Job and Scheduled Actions
- GO, Java api
- Deprecate onevm update-chart, delete-chart
* The commands are replaced by sched-update and sched-delete
* Refactor method deprecate_command, it's still possible to run the
command
* Delete 'shutdown' and 'delete' commands deprecated years ago
* Fix --verbose option for sched-update and sched-delete
- Re-implementation of scheduled actions, now are managed and executed
by oned
- Backup Job objects, API, and CLI commands
* Add Sched actions and sg (de)attach to VM_*_OPERATION
* Add Backup cancel action
* For consistency add poweroff migrate, alias (de)attach and nic update to set_auth_ops
* Datastores (fs/shared) can set QCOW2_STANDALONE to create disk images without backing files. This will increase clone times but will not have any dependencies.
New option for datastore driver (--stdin) that sends driver information
through stdin. Driver actions will read stdin if the first argument is
'-'. This change is compatible with drivers that read input from argument command
line. By default the driver will work using the command line arguments.
Monitor scripts part of the transfer manager are also updated
File oned.conf is changed to use stdin by default

When (for whatever reason) opennebula-ssh-agent gets killed
it leaves existing socket and following start fails with
opennebula-ssh-agent[2333]: unix_listener: cannot bind to path /var/run/one/ssh-agent.sock: Address already in use
This commit add a new attribute to the VM template MEMORY_RESIZE_MODE.
It can be:
- BALLOONING to increase/decrease the memory balloon
- HOTPLUG to add/remove memory modules to the VM
By default VMs will use BALLOONNING if not specified.

* VNET updates trigger a driver action on running VMs with NICs in the
network.
* VNET includes a sets with VM status: updated, outdated, error and
updating. With VMs in each state.
* VNET flags error situations with a new state UPDATE_FAILURE.
* The same procedure is applied when an AR is updated (only VMs in that
AR are updated).
* A new options in the one.vn.recover API call enable to recover or
retry this VM update operations.
* The following attributes can be live-updated per VNET driver:
- PHYDEV (novlan, vlan, ovs driver)
- MTU (vlan, ovs driver)
- VLAN_ID (vlan, ovs driver)
- QINQ_TYPE (ovs driver)

BACKUP INTERFACE
=================
* Backups are exposed through a a special Datastore (BACKUP_DS) and
Image (BACKUP) types. These new types can only be used for backup'ing
up VMs. This approach allows to:
- Implement tier based backup policies (backups made on different
locations).
- Leverage access control and quota systems
- Support differnt storage and backup technologies
* Backup interface for the VMs:
- VM configures backups with BACKUP_CONFIG. This attribute can be set
in the VM template or updated with updateconf API call. It can include:
+ BACKUP_VOLATILE: To backup or not volatile disks
+ FS_FREEZE: How the FS is freeze for running VMs (qemu-agent,
suspend or none). When possible backups are crash consistent.
+ KEEP_LAST: keep only a given number of backups.
- Backups are initiated by the one.vm.backup API call that requires
the target Datastore to perform the backup (one-shot). This is
exposed by the onevm backup command.
- Backups can be periodic through scheduled actions.
- Backup configuration is updated with one.vm.updateconf API call.
* Restore interface:
- Restores are initiated by the one.image.restore API call. This is
exposed by oneimage restore command.
- Restore include configurable options for the VM template
+ NO_IP: to not preserve IP addresses (but keep the NICs and network
mapping)
+ NO_NIC: to not preserve network mappings
- Other template attributes:
+ Clean PCI devices, including network configuration in case of TYPE=NIC
attributes. By default it removes SHORT_ADDRESS and leave the "auto"
selection attributes.
+ Clean NUMA_NODE, removes node id and cpu sets. It keeps the NUMA node
- It is possible to restore single files stored in the repository by
using the backup specific URL.
* Sunstone (Ruby version) has been updated to expose this feautres.
BACKUP DRIVERS & IMPLEMENTATION
===============================
* Backup operation is implemented by a combination of 3 driver operations:
- VMM. New (internal oned <-> one_vmm_exec.rb) to orchestrate
backups for RUNNING VMs.
- TM. This commit introduces 2 new operations (and their
corresponding _live variants):
+ pre_backup(_live): Prepares the disks to be back'ed up in the
repository. It is specific to the driver: (i) ceph uses the export
operation; (ii) qcow2/raw uses snapshot-create-as and fs_freeze as
needed.
+ post_backup(_live): Performs cleanning operations, i.e. KVM
snapshots or tmp dirs.
- DATASTORE. Each backup technology is represented by its
corresponfing driver, that needs to implement:
+ backup: it takes the VM disks in file (qcow2) format and stores it
the backup repository.
+ restore: it takes a backup image and restores the associated disks
and VM template.
+ monitor: to gather available space in the repository
+ rm: to remove existing backups
+ stat: to return the "restored" size of a disk stored in a backup
+ downloader pseudo-URL handler: in the form
<backup_proto>://<driver_snapshot_id>/<disk filename>
BACKUP MANAGEMENT
=================
Backup actions may potentially take some time, leaving some vmm_exec threads in
use for a long time, stucking other vmm operations. Backups are planned
by the scheduler through the sched action interface.
Two attributes has been added to sched.conf:
* MAX_BACKUPS max active backup operations in the cloud. No more
backups will be started beyond this limit.
* MAX_BACKUPS_HOST max number of backups per host
* Fix onevm CLI to properly show and manage schedule actions. --schedule
supports now, as well as relative times +<seconds_from_stime>
onvm backup --schedule now -d 100 63
* Backup is added as VM_ADMIN_ACTIONS in oned.conf. Regular users needs
to use the batch interface or request specific permissions
Internal restructure of Scheduler:
- All sched_actions interface is now in SchedActionsXML class and files.
This class uses references to VM XML, and MUST be used in the same
lifetime scope.
- XMLRPC API calls for sched actions has been moved to ScheduledActionXML.cc as
static functions.
- VirtualMachineActionPool includes counters for active backups (total
and per host).
SUPPORTED PLATFORMS
====================
* hypervisor: KVM
* TM: qcow2/shared/ssh, ceph
* backup: restic, rsync
Notes on Ceph
* Ceph backups are performed in the following steps:
1. A snapshot of each disk is taken (group snapshots cannot be used as
it seems we cannot export the disks afterwards)
2. Disks are export to a file
3. File is converted to qcow2 format
4. Disk files are upload to the backup repo
TODO:
* Confirm crash consistent snapshots cannot be used in Ceph
TODO:
* Check if using VM dir instead of full path is better to accomodate
DS migrations i.e.:
- Current path: /var/lib/one/datastores/100/53/backup/disk.0
- Proposal: 53/backup/disk.0
RESTIC DRIVER
=============
Developed together with this feature is part of the EE edtion.
* It supports the SFTP protocol, the following attributes are
supported:
- RESTIC_SFTP_SERVER
- RESTIC_SFTP_USER: only if different from oneadmin
- RESTIC_PASSWORD
- RESTIC_IONICE: Run restic under a given ionice priority (class 2)
- RESTIC_NICE: Run restic under a given nice
- RESTIC_BWLIMIT: Limit restic upload/download BW
- RESTIC_COMPRESSION: Restic 0.14 implements compression (three modes:
off, auto, max). This requires repositories version 2. By default,
auto is used (average compression without to much CPU usage)
- RESTIC_CONNECTIONS: Sets the number of concurrent connections to a
backend (5 by default). For high-latency backends this number can be
increased.
* downloader URL: restic://<datastore_id>/<snapshot_id>/<file_name>
snapshot_id is the restic snapshot hash. To recover single disk images
from a backup. This URLs support:
- RESTIC_CONNECTIONS
- RESTIC_BWLIMIT
- RESTIC_IONICE
- RESTIC_NICE
These options needs to be defined in the associated datastore.
RSYNC DRIVER
=============
A rsync driver is included as part of the CE distribution. It uses the
rsync tool to store backups in a remote server through SSH:
* The following attributes are supported to configure the backup
datastore:
- RSYNC_HOST
- RSYNC_USER
- RSYNC_ARGS: Arguments to perform the rsync operatin (-aS by default)
* downloader URL: rsync://<ds_id>/<vmid>/<hash>/<file> can be used to recover
single files from an existing backup. (RSYNC_HOST and RSYN_USER needs
to be set in ds_id
EMULATOR_CPUS
=============
This commit includes a non related backup feature:
* Add EMULATOR_CPUS (KVM). This host (or cluster attribute) defines the
CPU IDs where the emulator threads will be pinned. If this value is
not defined the allocated CPU wll be used when using a PIN policy.

(cherry picked from commit d4fcd134dc293f2b862086936db4d552792539fa)
- SHORT_ADDRESS can be used to select specific devices (useful on
homogenous clusters or nic attach operations). This name has been
selected because of:
1. It is the attrbute shown host info
2. It does not collide with the reserved ADDRESS attribute
- New test and add functions that considers both allocation methods: by
name (VENDOR/CLASS/DEVICE) or address (SHORT_ADDRESS)
- Parameter check on VM creation
- revert and add method use the same pci_attribute function to add info
to the VM PCI attribute
- Remove well-known attributes when parsing PCI devices (ADDRESS,
PREV_ADDRES, BUS, FUNCTION, SLOT, NUMA_NODE, UUID)
- Support for attach and detach NIC with PCI attributes
* onevm_exec.rb looks for PCI devices for ATTACH=YES when attaching/detaching an interface
* script action are now written in Ruby
* KVM module with common actions (hostdev/interface device str)
* Minor changes in xmlparser and OpenNebulaVM classes
- PCI selection options to onevm nic-attach:
* pci short_address
* pci_device device ID
* pci_vendor vendor ID
* pci_class class ID
- VF can be configured by setting some parameters through IP link (e.g.
MAC or VLAN_ID). This commit includes a mixin to activate_vf
* one_vmm_exec.rb looks for PCI VN_MAD drivers
* VM class (VNM) adds a @pcis array
* activate_vf should be called in the pre stage. The following drivers
acticate VFs (VLAN_ID is implemented as 802.1Q tag)
- 802.1Q
- bridge
- fw
- ovswitch
* Supported attributes for VF:
- MAC
- VLAN_ID
- spoof checking (SPOOFCHK)
- trust (TRUST)
- Predictable PCI addresses for guests is only enabled if PCI bus 1
is present (PCI bridge bus cannot be hotplugged)
- Improve integration with Libvirt/QEMU:
* When attach, only activate the VF being attached
* Attach: Use <interface> and not <hostdev> for VF. There seems to be a race
condition between accessing the vfio device and permission setup.
* Attach: Remove address on attach as it may fail beacuse PCI controller
is not present, e.g.:
ATTACHNIC: Could not attach NIC to 28534240: error: Failed to attach device
from /dev/fd/63 error: XML error: Invalid PCI address 0000:01:01.0.
Only PCI buses up to 0 are available ExitCode: 1
* Detach: Detach always use <hostdev> as libvirt fails to identified the
device just by address when using <interface>
- Suntone Support: The "Hardware" profile of a network interface (NIC) of a VM can be of three types, now exposed in Sunstone:
* "Emulated" it includes the hardware model emulated by Qemu
* "PCI - Automatic" oned hw scheduler will pick the best PCI device for the NIC
* "PCI - Manual" user can specify the PCI device by its short-address as shown in host information
This commits also enables the attach/detach operations on PCI based NICs in Suntone. *Note*: only for KVM VMs
