 Just a note: since features described in the article are not fully finalized, they are not merged to the main development branch yet and live in [their own branch](https://github.com/metta-systems/vesper/tree/feature/chainboot), which is subject to frequent rebases. Caveat emptor!

+RustyHermit is a unikernel targeting a scalable and predictable runtime for high-performance and cloud computing.
+
+This month, we integrated a [virtual i/o device driver](https://docs.oasis-open.org/virtio/virtio/v1.1/csprd01/virtio-v1.1-csprd01.html), which is based on memory mapped i/o and doesn't depend on PCI device specification.
+For instance, micro VMs like [Firecracker](https://firecracker-microvm.github.io) and Qemu's [microvm machine type](https://qemu.readthedocs.io/en/latest/system/i386/microvm.html) don't support the PCI specification to accelerate the boot time and to improve the performance.
+With this device driver, `rusty-hermit` is able to run on Qemu's microvm platform.
+We are working to support Firecracker in the near future.
