Hello,

Any news about that ?

[bineesh-n]

@chargio I think you have "Fedora_36_tools" VM already existing. Did you try unregistering that before packer build ?

Hello this is non-obvious, as at least in my version of Parallels (18.3.2 (53621)) there is no drop-down menu with a 'unregister VM' option, so it was this post that I found that is old but suggests a way forward, which worked by running

prlctl list -a

get the UUID of the image to use, ensuring it's shutdown and then and doing a

prlctl unregister <uuid>

and retrying.
