Open source Cloud Hypervisor adds (maybe futile) no-AI-code policy

The Cloud Hypervisor project has introduced a No AI code policy. Cloud Hypervisor started life in 2018 as a joint effort between Google, Intel, Amazon, and Red Hat – all of which wanted to share their work on virtualization components to speed their respective efforts to create virtual machine monitors and hypervisors. The …

Adding support for inter-VM shared memory

Clearly, I know nothing about VMs - 'cos that sounds like it is opening up new and exciting ways for VMs to corrupt each other, which goes completely against the idea of having VMs in the first place (if you want memory sharing between processes then run them on the same machine in the first place, virtual or otherwise).

(Unless, is this just really bad naming for a.n.other feature, such as dynamically (re)issuing physical memory between VMs so they get just the amount they need, at the moment? Without actually transferring data between them, i.e. scrubbing the memory contents before allowing a VM to access it).

Re: Adding support for inter-VM shared memory

It's apparently used for low latency inter-VM communication. QEMU (used with KVM) has this, and to the guest OS it appears as an emulated PCI device.

Hmm. I see no possible downside.

Re: Adding support for inter-VM shared memory

Think of it like a NAS, but in physical RAM to erase most of the latency.

I assume the actual low-level API is a bit smarter than SMB or NFS, but similar basic concept.
