kandi X-RAY | libvfio-user Summary

libvfio-user is a C library. libvfio-user has no vulnerabilities, it has a Permissive License and it has low support. However libvfio-user has 1 bugs. You can download it from GitHub.

vfio-user is a framework that allows implementing pci devices in userspace. clients (such as [qemu] talk the [vfio-user protocol] over a unix socket to a server. this library, libvfio-user, provides an api for implementing such servers. [vfio] is a kernel facility for providing secure access to pci devices in userspace (including pass-through to a vm). with vfio-user, instead of talking to the kernel, all interactions are done in userspace, without requiring any kernel component; the kernel vfio implementation is not used at all for a vfio-user device. put another way, vfio-user is to vfio as [vhost-user] is to vhost. the vfio-user protocol is

Support

With the client support found in [cloud-hypervisor](https://github.com/cloud-hypervisor/cloud-hypervisor/) or the in-development [qemu](https://gitlab.com/qemu-project/qemu) support, most guest VM use cases will work. See below for some details on how to try this out. However, guests with an IOMMU (vIOMMU) will not currently work: the number of DMA regions is strictly limited, and there are also issues with some server implementations such as SPDK’s virtual NVMe controller. Currently, libvfio-user has explicit support for PCI devices only. In addition, only PCI endpoints are supported (no bridges etc.).
