In the hypervisor support mode, QEMU either acts as a Virtual Machine Manager (VMM) or as a device emulation back-end for virtual machines running under a hypervisor. The most common is Linux's KVM but the project supports a number of hypervisors including Xen , Apple's HVF, Windows' WHPX, and NetBSD's NVMM.
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.
Simics is built for high performance execution of full-system models, and uses both binary translation and hardware-assisted virtualization to increase simulation speed. It is natively multithreaded and can simulate multiple target (or guest) processors and boards using multiple host threads.
Kimchi – web-based virtualization management tool for KVM; Virtual Machine Manager – supports creating, editing, starting, and stopping KVM-based virtual machines, as well as live or cold drag-and-drop migration of VMs between hosts. Proxmox Virtual Environment – an open-source virtualization management package including KVM and LXC. It ...
SeaBIOS is an open-source implementation of an x86 BIOS, serving as a freely available firmware for x86 systems. Aiming for compatibility, it supports standard BIOS features and calling interfaces that are implemented by a typical proprietary x86 BIOS.
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]
CVE-2011-1751 QEMU-KVM: PIIX4 emulation does not check if a device is hotpluggable before unplugging [7] CVE-2012-0217 The x86-64 kernel system-call functionality in Xen 4.1.2 and earlier; CVE-2014-0983 Oracle VirtualBox 3D acceleration multiple memory corruption; CVE-2015-3456 VENOM: buffer-overflow in QEMU's virtual floppy disk controller
When debugging a concurrent and distributed system of systems, a bootloop (also written boot loop or boot-loop) is a diagnostic condition of an erroneous state that occurs on computing devices; when those devices repeatedly fail to complete the booting process and restart before a boot sequence is finished, a restart might prevent a user from ...
