We can migrate a VMware based image, vmdk
, to other disk image formats. This can be achieved using an image conversion utility. This same utility can be used to verify that the conversion worked properly. Once the image has been converted, it can be uploaded to OpenStack Image Service.
To begin with, ensure you are logged in to our Ubuntu client where we will be doing the image conversion. Make sure you have qemu-util
installed; if not, you may install it using the following:
sudo apt-get install qemu-utils
Carry out the following steps to convert a VMDK image to the QCOW2 format:
Verify the image using the following command:
qemu-img info custom-iso-1415990568-disk1.vmdk
You will get the following output:
