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.
