KVM. 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 is able to offer virtualization for x86, PowerPC, and S/390 guests.
How does QEMU KVM work?
KVM is a virtualization feature in the Linux kernel that lets a program like qemu safely execute guest code directly on the host CPU. … When the guest accesses a hardware device register, halts the guest CPU, or performs other special operations, KVM exits back to qemu.
What are the differences between QEMU and KVM?

Does QEMU use KVM?
Unlike native QEMU, which uses emulation, KVM is a special operating mode of QEMU that uses CPU extensions (HVM) for virtualization via a kernel module. Using KVM, one can run multiple virtual machines running unmodified GNU/Linux, Windows, or any other operating system.
What is QEMU Linux?
QEMU is a generic and open source machine emulator and virtualizer. … QEMU supports virtualization when executing under the Xen hypervisor or using the KVM kernel module in Linux. When using KVM, QEMU can virtualize x86, server and embedded PowerPC, 64-bit POWER, S390, 32-bit and 64-bit ARM, and MIPS guests.

Who owns KVM?
Avi Kivity began the development of KVM in mid-2006 at Qumranet, a technology startup company that was acquired by Red Hat in 2008. KVM surfaced in October, 2006 and was merged into the Linux kernel mainline in kernel version 2.6. 20, which was released on 5 February 2007. KVM is maintained by Paolo Bonzini.
Why KVM is better than Xen?
To answer the question raised above, Xen is better than KVM in terms of virtual storage support, high availability, enhanced security, virtual network support, power management, fault tolerance, real-time support, and virtual CPU scalability.

How do I know if QEMU is using KVM?
Other ways to do the diagnostic: if you have access to the QEMU monitor (Ctrl-Alt-2, use Ctrl-Alt-1 to get back to the VM display), enter the “info kvm” command and it should respond with “KVM support: enabled”
Na KVM e felletseng ka botlalo?
