Here some quicks steps on how to run a VMware virtual machine with Windows on it on KVM and libvirt. These are mainly notes for myself but they might still be helpful.

  1. If the VMware virtual disk consists of multiple numbered vmdk files, convert these with

qemu-img convert Windows-s0??.vmdk windows.img

where the question mark stands for the different numbers. In my case there were files called Windows-s001.vmdk to Windows-s021.vmdk.

  1. Move the converted image file to /var/lib/libvirt/images/

mv windows.img /var/lib/libvirt/images/

  1. Start virt-manager and import the image

  2. Start the VM, connect to it via virt-manager and configure the Windows network. Set the IP address to an available IP, the netmask to 255.255.255.255, the Gateway to your physical servers IP address and enter a DNS server, .e.g. 8.8.8.8.

  3. Reactive Windows since the hardware changed.
