Failed to import VM from URL #312

Closed qwang1 closed 6 years ago

qwang1 commented 6 years ago

Hi there,

I failed to use import-vm-apb to import a vm or template via URL. I used this as disk image: http://download.eng.bos.redhat.com/brewroot/packages/rhel-guest-image/7.6/70/images/rhel-guest-image-7.6-70.x86_64.qcow2 . Anything I did wrong? Besides, I'd like to know why the command "oc logs" shows it sticks when "Get content metadata", but run ansible-playbook in the sandbox shows it sticks when "Change project". Thanks.

Downloaded image http://www.tinycorelinux.net/9.x/x86/release/TinyCore-9.0.iso , it worked.

Questions:

  1. Downloading big size of image is supported? AFAIK, 3GB iso images don't work.
  2. Converting qcow2 -> raw is supported?

Thanks.

I think this issue belongs to the CDI repo. qcow2 to raw is supported, we demonstrated this flow

qwang1 commented 6 years ago

I used a small sized qcow2, it works.
