 RustyHermit is a unikernel targeting a scalable and predictable runtime for high-performance and cloud computing.
-This month, we integrate a [virtual i/o device driver](https://docs.oasis-open.org/virtio/virtio/v1.1/csprd01/virtio-v1.1-csprd01.html), which 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) doesn'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.
