QEMU als Linux-Alternative zu VirtualBox
Aktualisiert am
Unser Fazit
QEMU, especially when combined with KVM, can replace VirtualBox for most Linux users who need to run multiple guest OS instances. It supports x86 and ARM, offers snapshots, USB and network passthrough, shared folders via virtfs, and headless operation. It is more flexible and often faster on Linux, but its configuration is more manual and the GUI is less polished than VirtualBox’s. It is best suited for power users, developers, and server admins who are comfortable with command‑line tools or libvirt.

Was gleich funktioniert
- Both can run x86 and ARM guests
- Both support snapshots and state management
- Both provide USB and network passthrough
- Both allow shared folders between host and guest
- Both can be operated headlessly
Was anders ist
- QEMU requires KVM for near‑native speed; VirtualBox has built‑in acceleration
- QEMU’s default UI is command‑line or libvirt‑based; VirtualBox has a rich GUI
- QEMU supports a wider range of guest architectures (RISC‑V, PowerPC)
- QEMU can emulate many more hardware devices, but configuration is more complex
- VirtualBox offers easier VM import/export via .ova files; QEMU uses raw or qcow2 images
Ihre VirtualBox-Dateien öffnen
VirtualBox .vdi files can be used directly with QEMU by specifying the format, e.g., qemu-img convert -f vdi -O qcow2 file.vdi new.qcow2. Exporting a QEMU image to a .vdi is possible with qemu-img, but the process is manual. For .ova packages, you need to extract the disk image and create a new QEMU VM.
Von VirtualBox zu QEMU wechseln – Schritt für Schritt
- 1. Install QEMU and libvirt on your Linux distro.
- 2. Convert existing VirtualBox VDI to QCOW2: qemu-img convert -f vdi -O qcow2 old.vdi new.qcow2.
- 3. Create a new VM with virt-install or virt-manager, pointing to new.qcow2.
- 4. Reconfigure network, USB, and shared folder settings in virt-manager.
- 5. Test the VM, then delete the old VirtualBox VM.
Wichtige Funktionen von QEMU
- Full-System-Emulation für x86, ARM, RISC-V und mehr
- Hardwarebeschleunigung über KVM für nahezu native Leistung
- Unterstützt mehrere Festplatten-Image-Formate (qcow2, raw, vdi)
- Netzwerk-Bridging und NAT-Unterstützung
- USB-Passthrough und Geräteemulation
- Snapshot-Unterstützung für schnelles Speichern/Wiederherstellen
- Integration mit libvirt für fortgeschrittenes Management
- Breite Hardwarekompatibilität einschließlich GPU-Passthrough

Does QEMU support VirtualBox snapshots?
QEMU has its own snapshot mechanism; you cannot directly import VirtualBox snapshots, but you can convert the base image and create new snapshots in QEMU.
Is QEMU suitable for running Windows guests?
Yes, QEMU/KVM can run Windows guests with near‑native performance, provided the host CPU supports virtualization extensions.
Can I use QEMU on a headless server?
Absolutely. QEMU can be launched in headless mode, controlled via libvirt or command line, making it ideal for server environments.
