Questions related to Image issues

  • Since I am new to fog, I need your assistance in understanding imaging part.

    I have customized Ubuntu 16.04 desktop created in KVM. The name of image is ubuntu-16.04.img. I want to install this image to my other VMs using fog.

    For testing, I copied this image file to /images folder as ubuntu-16.04 and created new image from console, but I am running into problem here. The size of disk on server is showing 0.

    Now I am not sure if I am doing it correctly. If I am making mistakes, can somebody please guide me in process?

    Is it also possible to use dm-crypt/LUKS for software encryption? If yes, can you tell me how to do it?

    @unltdlove2u How did you create that ubuntu-16.04.img in the first place? Sounds to me as if this is just your KVM image file, right? Well with FOG the steps to create an image is: register the machine (as well KVM should work if all network and DHCP is setup properly), schedule a capture/upload task and let the client upload its disk contents.

    What you are asking for is a way to convert your KVM disk image into a FOG image. Might be possible but it’s not supported. Search the forum for convert vmdk and such VM disks. I think some people have done it but it’s probably a lot of work and I am not sure it’s worth it.

    For dm-crypt/LUKS you need to let FOG do a sector by sector copy (also called dd) as it can’t read the encrypted filesystem stuff. The FOG image will be very big as it contains unused sectors as well.
