libguestfs is a C library and a set of tools for accessing and modifying virtual disk images used in platform virtualization.The tools can be used for viewing and editing virtual machines (VMs) managed by libvirt and files inside VMs, scripting changes to VMs, creating VMs, and much else besides.

Kernel-based Virtual Machine (KVM) is a free and open-source virtualization module in the Linux kernel that allows the kernel to function as a hypervisor. It was merged into the mainline Linux kernel in version 2.6.20, which was released on February 5, 2007. [ 1 ]
libvirt is an open-source API, daemon and management tool for managing platform virtualization. [3] It can be used to manage KVM , Xen , VMware ESXi , QEMU and other virtualization technologies. These APIs are widely used in the orchestration layer of hypervisors in the development of a cloud-based solution.
The database and FUSE-based Proxmox Cluster file system (pmxcfs [31]) makes it possible to perform the configuration of each cluster node via the Corosync communication stack with SQLite engine. [13] Another HA-related element in PVE is the distributed file system Ceph, which can be used as a shared storage for guest machines. [32]
KVM (Kernel-based Virtual Machine) is a FreeBSD and Linux kernel module that allows a user space program access to the hardware virtualization features of various processors, with which QEMU can offer virtualization for x86, PowerPC, and S/390 guests. When the target architecture is the same as the host architecture, QEMU can make use of KVM ...

A user space program may also pass packets into a TUN/TAP device. In this case the TUN/TAP device delivers (or "injects") these packets to the operating-system network stack thus emulating their reception from an external source.
The vast majority of Intel server chips of the Xeon E3, Xeon E5, and Xeon E7 product lines support VT-d. The first—and least powerful—Xeon to support VT-d was the E5502 launched Q1'09 with two cores at 1.86 GHz on a 45 nm process. [2]
