Session
Confidential computing - making VM guest secrets harder for
the hypervisor to access - is getting more and more important as
time goes by.
Virtio (and paravirtualization generally), fundamentally, can be thought of as
a means of improving guests by making use of hyprevisor functionality. To what
level can this still be beneficial when the guest does not want to fully trust
the hypervisor?
This talk will try to address these questions, by touching on the following
areas:
- review of new features / devices and how they interact with
confidential computing - status and plans of hardening (improving confidentiality)
with virtio on Linux - known open issues and how you can help
