Description

In app/models/concerns/orchestration/compute.rb file there is this method:

def queue_compute
    return unless compute? && errors.empty?
    # Create a new VM if it doesn't already exist or update an existing vm
    vm_exists? ? queue_compute_create : queue_compute_update
end

When I read the ternary operator it seems to do the exact contrary of what it is explained in the comment.
And when I test it, indeed it does not create the VM in compute provider.

I think it should be:

def queue_compute
    return unless compute? && errors.empty?
    # Create a new VM if it doesn't already exist or update an existing vm
    !vm_exists? ? queue_compute_create : queue_compute_update
end

Then it works and it finally creates the new VM in compute provider.
I am surprised that nobody else found this before.
Maybe I misunderstood something?

Could you open a pull request whith this, please?

Personally I'd find this easier to follow the logic:

    vm_exists? ? queue_compute_update : queue_compute_create

I'm unsure about the actual impact of this bug.

If it's relevant, it would good to have it as a separate commit to cherry-pick it down to the supported releases.

The PR refactors vm_exists? but my original issue still remains. I will make another issue (feature enhancement exactly) and a new PR.
