If you prefer a graphical interface:
qemu-img convert -f vhdx -O qcow2 -c Windows11_Dev.vhdx windows11_compressed.qcow2
This method gives you a bootable Windows 11 QCOW2 image in minutes.
In the VM XML, set:
<driver name="qemu" type="qcow2" cache="writeback" io="threads"/>
writeback gives host-level caching, excellent for QCOW2. windows 11 qcow2 download
After installing Windows 11 and removing bloatware, reclaim space:
# Inside Windows: sdelete -z c: (zero free space)
# On host:
qemu-img convert -O qcow2 -c windows11.qcow2 windows11_compacted.qcow2
The -c flag enables compression.
We will create a QCOW2 image from scratch using the official Windows 11 ISO. This method ensures integrity.
Several open-source projects provide pre-installed, pre-configured Windows 11 QCOW2 images to save time on installation. These are typically "Evaluation" versions valid for 90 days or fully installed raw images converted to QCOW2. If you prefer a graphical interface:

Note on Security: Be cautious when downloading pre-built disk images from third-party websites. Always verify the source and scan the file for malware if possible.
Q1: Can I run Windows 11 QCOW2 on VMware?
No. VMware uses VMDK. Convert QCOW2 to VMDK with qemu-img convert -f qcow2 -O vmdk.
Q2: Is there an official Windows 11 QCOW2 from Microsoft?
No. Microsoft provides VHDX (for Hyper-V) and ISO (for installation). QCOW2 is a third-party standard for QEMU/KVM. Start the VM and install Windows 11 normally
Q3: How large should my QCOW2 image be?
Start with 60GB dynamic. Windows 11 requires at least 32GB, but updates will need more.
Q4: Does Windows 11 work with QCOW2 snapshots?
Yes, perfectly. Ensure the QEMU guest agent is installed for consistent live snapshots.
Q5: Can I run this on macOS with UTM?
Yes. UTM uses QEMU/QCOW2 under the hood. The same principles apply.
