qemu-img for Windows

QEMU disk image utility for Windows. It is used for converting, creating, and consistency checking of various virtual disk formats. It is compatible with Hyper-V, KVM, VMware, VirtualBox, and Xen virtualization solutions. This build has been optimized for Windows Server (x64).

Usage examples

Convert a QCOW2, RAW, VMDK or VDI image to VHDX

1	qemu-img.exe convert source.img -O vhdx -o subformat=dynamic dest.vhdx

Convert a QCOW2, RAW, VMDK or VDI image to VHD

1	qemu-img.exe convert source.img -O vpc -o subformat=dynamic dest.vhd

Subformat can be either “dynamic” or “fixed” for VHD (vpc) or VHDX.

Note: use the fixed VHD subformat for Azure, the conversion will automatically take care of the required 1MB virtual size alignment.

Check a virtual disk for consistency

1	qemu-img.exe check source.qcow2

Get info about a virtual disk

1	qemu-img.exe info image.qcow2

Run qemu-img.exe -h or see the manual page for a complete list of all supported options.
