At work we have a really slow bandwidth and I need to intensively create VM's that are provisioned with chef and preparing take long time to download chef client.
There is a way to cache it ?
edit:
Since I use Vagrant, I found to just save the box with chef client already installed.
But the bootstrap template work too
As stated here you may replace knife solo prepare by a knife bootstrap.
You'll have to create your own templates depending on your architecture in
https://github.com/chef/chef/blob/master/lib/chef/knife/bootstrap/
There's exemples inside, the main idea is to comment the call to opscode chef installer and to set the download location directly.
Default template is chef-full.rb

Thanks coderanger for the link to github instead of a path.
