    Phoronix: Intel's Cloud Hypervisor 0.3 Adds Block Device Offloading, Paravirtualized IOMMU

    Intel developers have been working on the Cloud Hypervisor that is written in Rust and built atop KVM as an open-source VMM designed for running modern cloud workloads while being focused on just supporting modern software/interfaces and relying upon para-virtualized (VirtIO) devices without legacy support. This week marked a new release of this forward-looking KVM-based hypervisor solution...

    So does this occupy the same slot in the stack as QEMU?

      does anybody know a way to get a console? serial (like -serial mon:stdio in qemu) is preffered

        Yes, it sits in the same place as QEMU when the latter is using KVM. Both are VMMs running on top of KVM.

          Yes. You can either use virtio-console or a serial TTY for that. Assuming you're doing direct kernel boot:

          - For virtio-console, you only need to specify "console=hvc0" from your kernel command line
          - serial TTY will give you very early kernel messages. Pass "console=ttyS0" to your kernel command line and pass "--console off --serial tty" to the cloud-hypervisor command line.

          If you have any issues getting getting your console working, please fill an issue on our github: https://github.com/intel/cloud-hypervisor
