Using virtio-blk with SEV on host kernels prior to 5.1 didn't work because of SWIOTLB limitations and the way virtio has to use it over DMA-API for SEV (see [1] for detailed info). That is no longer true, so reword the kbase article accordingly. For reference, these are the upstream kernel commits lifting the virtio-blk limitation: abe420bfae528c92bd8cc5ecb62dc95672b1fd6f 492366f7b4237257ef50ca9c431a6a0d50225aca 133d624b1cee16906134e92d5befb843b58bcf31 e6d6dd6c875eb3c9b69bb640419405726e6e0bbe fd1068e1860e44aaaa337b516df4518d1ce98da1 [1] https://lore.kernel.org/linux-block/20190110134433.15672-1-joro@8bytes.org/ Signed-off-by: Erik Skultety <eskultet@redhat.com> Reviewed-by: Martin Kletzander <mkletzan@redhat.com> |

Libvirt API for virtualization
Libvirt provides a portable, long term stable C API for managing the virtualization technologies provided by many operating systems. It includes support for QEMU, KVM, Xen, LXC, bhyve, Virtuozzo, VMware vCenter and ESX, VMware Desktop, Hyper-V, VirtualBox and the POWER Hypervisor.
For some of these hypervisors, it provides a stateful management daemon which runs on the virtualization host allowing access to the API both by non-privileged local users and remote users.
Layered packages provide bindings of the libvirt C API into other languages including Python, Perl, PHP, Go, Java, OCaml, as well as mappings into object systems such as GObject, CIM and SNMP.
Further information about the libvirt project can be found on the website:
