* 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* VNET includes a sets with VM status: updated, outdated, error and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)
- CVLANS (ovs driver)
- VLAN_TAGGED_ID (ovs driver)
- OUTER_VLAN_ID (ovs driver)
- INBOUND_AVG_BW (SG, ovs driver + KVM)
- INBOUND_PEAK_BW (SG, ovs driver + KVM)
- INBOUND_PEAK_KB (SG, ovs driver + KVM)
- OUTBOUND_AVG_BW (SG, ovs driver + KVM)
- OUTBOUND_PEAK_BW (SG, ovs driver + KVM)
- OUTBOUND_PEAK_KB (SG, ovs driver + KVM)
* New API call one.vm.updatenic, allows to update individual NICs
without the need of detach/attach (only QoS supported).
* Update operations for: 802.1Q, bridge, fw, ovswitch, ovswitch_vxlan
and vxlan network drivers.
* VNET attributes (old values) stored in VNET_UPDATE to allow
implementation of update operations. The attribute is removed after a
successful update.
* Updates to CLI onevnet (--retry option) / onevm (nicupdate command)
* XSD files updated to reflect the new data model
* Ruby and JAVA bindings updated: new VNET state and recover option, new
VM API call.
* Suntone and Fireedge implementation (lease status, recover option, new
states)
TODO: Virtual Functions does not support this functionality
iii
* By default use cache mode none and io native
* Option to choose from async io for read commands
* Create a single io script for qemu-io
* Fix error in ceph prebackup
- Adds new configuration attribute MODE: FULL or INCREMENTAL for
BACKUP_CONFIG. FULL backups uses a differen backup image.
- INCREMENTAL backup information is together with the backup image.
Example:
<BACKUP_INCREMENTS>
<INCREMENT>
<DATE><![CDATA[1667770552]]></DATE>
<ID><![CDATA[0]]></ID>
<PARENT_ID><![CDATA[-1]]></PARENT_ID>

</INCREMENT>
</BACKUP_INCREMENTS>
This information only appears on incremental backups
- Internal BACKUP_CONFIG data includes information about the current
active backup and the last increment id.
- Backup operation includes a new parameter: reset. This "closes" the
current active incremental chain and creates a new FULL backup.
- Backup drivers store backups with increment index (0 = FULL) e.g.
disk.0.0.
- Incremental backups are only allowed for VMs using all disks in qcow2
format.
- Backup configuration cannot be changed while doing a VM backup.
- Downloader strings includes backup chains <inc_id>:<backup_ref>,...
- Restic downloader has been updated to support backup chains. Disk
images are rebased across increments.
Disk images are consolidated and converted to qcow2 format before
backup. This commit increases the number of co-routines to increase the
parallelism of the operation
