| Purpose | QEMU is a generic and open source machine emulator and virtualizer. | Xen Orchestra visualizes, manages, backs up and delegates XCP-ng or XenServer infrastructure across any number of pools and sites without requiring an agent. |
| Security model | QEMU defines guest isolation requirements and recommends least privilege for processes and resources. | Vates describes XCP-ng and Xen Orchestra as fully open and auditable, and says security updates are not gated behind paid support. |

In their own words
QEMU
QEMU is a free, open-source machine emulator and virtualizer. System emulation models an entire machine, including its CPU, memory and devices, so it can run a guest operating system. User-mode emulation runs processes built for one CPU architecture on another. The package also includes qemu-img, a command-line utility for creating, converting and modifying disk images. QEMU can work with KVM, Xen and Hypervisor.Framework so guests can run directly on the host CPU. Supported build platforms include Linux, macOS, FreeBSD, NetBSD, OpenBSD and Windows. Windows support is limited to 64-bit, while macOS requires the newest version currently available; support for the prior version is eventually dropped. For complex networking and storage configurations, the project recommends management tools such as virt-manager. Its security guidance distinguishes virtualization with an accelerator and listed machine type from TCG non-virtualization use, which does not provide guest-isolation or security guarantees. QEMU is released under GNU GPL version 2, with some components under specific licenses.
