QEMU is a free and open-source emulator and virtualizer that can perform hardware virtualization.
QEMU is a hosted virtual machine monitor: it emulates the machine's processor through dynamic binary translation and provides a set of different hardware and device models for the machine, enabling it to run a variety of guest operating systems. It also can be used with Kernel-based Virtual Machine (KVM) to run virtual machines at near-native speed (by taking advantage of hardware extensions such as Intel VT-x). QEMU can also do emulation for user-level processes, allowing applications compiled for one architecture to run on another.
Released on Tuesday was QEMU 6.1.0-rc0 as the first test release working towards QEMU 6.1's stable debut before the end of August. QEMU 6.1 is another sizable feature release building off QEMU 6.0 that released at the end of April. QEMU remains an important piece of the Linux open-source virtualization stack and is also used on other platforms.
With QEMU 6.1.0-rc0, QEMU 6.1 is now under a hard feature freeze and will see weekly release candidates until ready to ship. The current plan is that QEMU 6.1.0 will be ready by mid-to-late August. Among the changes coming with QEMU 6.1 are:
