...

  • Next generation storage architecture (design approved; in progress)
  • Extract and report GPS coordinates to controller (if device has a cellular modem with GPS) (proposed)
  • Incremental image download (rsync-like) (proposed)
  • Better enforcement of volume size limits for the OCI-derived volumes (proposed - after storage rework)
  • EVE self-monitor and log memory and disk usage increases - (first cut done - https://github.com/lf-edge/eve/pull/2023)
  • EVE report more hardware counters? (e.g., disk/SSD S.M.A.R.T counters) (proposed)
  • Combine eve, adam, and eden and just call it "eve"? Commands then looks like: "eve pod deploy ...", "eve generate server", ... and maybe after all the config is done, a command like "eve generate image" could be used to create an EVE-OS image for a specific board or hw arch (proposed)
  • Expand EVE test coverage to improve overall stability: performance under stress; search for security vulnerabilities; automated code analysis; board farm daily and release testing (proposed)
  • Controlling "VM bundles" (see below for a bigger scope around Local Controller) via "run profiles"
    • Controller feature to define the run-profiles, will allow customer to define the set of VMs that form their applications
    • Modifiable via MetaData APIs
    • User-owned APP responsibled for providing a local API endpoint on the box
  • "VM bundle" VM version selection
  • Hardening USB passthrough
  • Hardening GPU passthrough
  • Custom CA for HTTPs downloads
  • GCP data store
  • USB or SAN datastore

Q1 2022

Storage

  1. NVMe/Vhost
    • Prototype
      • Implement creation of data queus
      • Rework Admin queue creation – move away from hardcoded implementation
      • Implement the minimum set of commands required to operate under linux
      • Implement Shadow Queue
      • Make sure works with Windows
    • Harden the prototype
      • Submit RFC patches to the mailing list once Prototype phase is ready
      • Address comments, work on cleaning up hacks
      • Run correctness tests, implement any missing bits an pieces
  2. ZFS
    • First official support
      • Revise current storage health reporting in Eve OS
      • Add
        • Reporting multiple disks
        • S.M.A.R.T reporting
        • Zpool status errors
      • Enable reporting in the cloud
    • Zvol direct-io evaluation
      • Based on Delphix efforts presented on OpenZFS Dev Summit 2021
    • Async DMU / Async CoW
      • Deferring the reads so writes are not blocked
    • Online pool grow
      • If more disks added to the pool

Testing/Validation

Release Engineering

Security

Future - to be planned

  • Support multiple disks using different forms of RAID configurations (might use ZFS)
  • Tailscale integration?
  • Build EVE as OCI layers (reduces size of EVE update downloads)
  • Local Controller
    • EVE toolkit (AKA MetaData server): read-only endpoints, protected by access control, physical access to the system required
      • Extending meta-data server API’s
      • provide local access to system metrics
      • provide a local access to change the run-profiles
    • HW Level metrics (IPMI-like): could be part of the above
  • CPU affinity
    • Controlling "VM bundles"
  • Infrastructure as code (Teraform plugin?)
  • Snapshot/differential VM upgrades
  • OCI observability
    • coredumps
    • crashkernel
  • Sensor I/O virtualization
  • Target upstream component for the next release
    • Alpine
    • Linux Kernel
    • Xen
    • Qemu
    • Golang
