List meeting participants using their @ mention names

List goals for this meeting (e.g., Set design priorities for FY19)

Review the project goals
- are the 4 (virtio, safety island, boot orchestration, written standards) still relevant
Potential Future Work
- Should we implement Xen support for rust-vmm’s vmm-reference?
  - might be useful but does it advance Stratos goals?
- rust-vmm bare metal backends
  - is it time to do a PoC for this?
  - would be hypervisor specific, but see how flexibile the crate method is
  - should it target 2 hypervisors (build time config)
- xen-virt model for QEMU ( )
  - enable more VirtIO devices via QEMU
- enabling more hypervisors - what about pKVM, it may have KVM in the title but it’s not totally transparent to VirtIO or probably rust-vmm at the moment
Any pre-discussion about virtio-camera?
- will discuss in more detail with stakeholders for the next meeting

AMD interested in
- Xen support
- QEMU support (IOREQ server)
AJB: what about safety island and boot orchestration
- Ayan: has a functional safety roadmap
- Tomas: we have our own boot orchestration
  - documentation of APIs is a useful piece of work
Tomas: are you interested in other hypervisors
- AJB: yes but we can’t do the work
- Tomas: will reach out
Tomas: QEMU stuff is number 1
Luka: we are interested in rust-vmm
- We deal with embedded network devices and firmware
- Good for building efficient VMM controller
- Looking at unikernels
- using it as a vmm to control things
- ublk io_uring (userspace block faster than network block storage)
Ayan: safety island and orcehstration (AJB: send notes)
Alysaa: virtio-gpu -vhost-user
- QEMU and CrosVM
- incompatible
- CrosVM sends dmabufs
- it would be nice to see a standardised version
- CrosVM tried to to bring things to to rust-vmm and then forked again
- virtio-gpu is really just a generalized memory sharing that happens to be used for gpus

Add action items to close the loop on open questions or discussion topics:

Alex Bennée write up some cards/refresh old ones for the 3 areas of work (rust-vmm monitor/Xen QEMU Virtio/virtio-vhost-user
