The record

Purpose: QEMU is a generic and open source machine emulator and virtualizer.
System emulation: System emulation provides a virtual model of an entire machine, including CPU, memory and emulated devices, to run a guest operating system.
User-mode emulation: User-mode emulation launches processes compiled for one CPU architecture on another architecture.
Disk utility: QEMU includes standalone command-line utilities such as qemu-img for creating, converting and modifying disk images.
Hypervisors: QEMU can work with KVM, Xen and Hypervisor.Framework to let guests run directly on the host CPU.
Supported hosts: The project lists Linux, macOS, FreeBSD, NetBSD, OpenBSD and Windows as supported build platforms.
Windows limit: Only 64-bit Windows is supported.
macOS support: QEMU requires the most recent macOS version currently available, with support for the previous version eventually dropped.
Linux packaging: QEMU is packaged by most Linux distributions, including Arch, Debian/Ubuntu, Fedora, Gentoo, RHEL/CentOS and SUSE.
Management integration: For complex networking and storage configurations, QEMU recommends management tools such as virt-manager from the libvirt project.
Security model: The virtualization security use case requires an accelerator such as KVM or HVF and a listed machine type; TCG non-virtualization use cases do not provide guest-isolation or security guarantees.
Security reporting: QEMU requires potential security issues to be filed as confidential GitLab issues and provides no SLA for responses.
Support channels: User support is available through the qemu-discuss mailing list, technical mailing lists, IRC or Matrix, documentation and the bug tracker.
License: QEMU is released under the GNU General Public License version 2, with some components under specific licenses.
