Agenda
Date: 30/9/2022 (poll @ https://doodle.com/meeting/organize/id/aKZB8Qne )
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 (STR-19: Virtio aware Xen model for QEMU for testing additional devicesClosed )
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
Discussion topics
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
