Kqemu virtualisation module for qemu

When QEMU is compiled with KQEMU support, the following option is added to QEMU: `-no-kqemu' Disable the usage of the QEMU Accelerator module (KQEMU). QEMU will work as usual but will be slower. This option can be useful to determine if emulation problems are coming from KQEMU. `-kernel-kqemu' Enable full virtualization mode for best performances. kqemu is a kernel module that "accelerates" QEMU virtualization by allowing guests to run some operations directly on the host's CPU. In this respect, it's similar to kvm. Beyond the kernel module, kqemu requires support from the QEMU userspace emulator to take advantage of the kqemu kernel hooks. Kqemu.sys file information. The process known as kqemu driver or KQEMU virtualisation module for QEMU belongs to software kqemu driver or KQEMU virtualisation module for QEMU by unknown. Description: Kqemu.sys is not essential for the Windows OS and causes relatively few problems. Kqemu.sys is located in the C:\Windows\System32\drivers folder. The really good thing about QEMU is that its architecture is designed to allow definition of new CPU types and new hardware devices. KVM is a kernel module that allows the use of Intel or AMD virtualization extensions technologies. This project is not part of the GNU Project. qvm86 is a kernel module to provide x86 virtualisation capabilities for the qemu emulator. Virtualisation allows "emulated" code to be run natively on the host cpu, using the CPU protection mechanisms to intercept and emulate priveleged events. qemu of 0.9.1 and earlier can use the kqemu accelerator. In the version after qemu1.0, kqemu cannot be used , mainly using the qemu- kvm acceleration module, and the acceleration effect and stability are significantly better than kqemu.

When used as a virtualizer, QEMU achieves near native performances by executing the guest code directly on the host CPU. A host driver called the QEMU accelerator (also known as KQEMU) is needed Being a kernel module, KQemu is able to execute most code unchanged, replacing only the lowest-level ring0-only instructions. In that case, userspace Qemu still allocates all the RAM for the emulated machine, and loads the code. The difference is that instead of recompiling the code, it calls KQemu to scan/patch/execute. 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. When the target architecture is the same as the host architecture
