servers.create with template_name creates an empty vm

[fmbiete]

Hi,

When using servers.create to create a new server, using template_name from a template, I end with a template withouth VIFs or VBDs.

That should not create a server (not a template), with cloned vifs and disks?

irb(main):020:0> vm_new = xenserver.servers.create(affinity: xenserver.hosts.first, name: 'NEW-MACHINE-FROM-TEMPLATE', template_name: template.name)

Ok. Thats the biggest change in the api. That template_name attribute was not a real attribute of XENSERVER but rather just a "boolean" attribute that would change completely the behavior of the VM creation and thus a lot of headaches to support it.

So this option was completely removed. That attribute does not exist anymore. You gotta dance as the XENSERVERapi now :smile: . No magic behind the scenes.

If you want to create a server from a template, just load the template and clone it:

@template = @conn.templates.find ....
@server = @template.clone
@server.provision

If you want to create a server from scratch, you gotta do a little more, like creating the disk, the vif, and installing the operational system.

Be sure to use fog-xenserver and not fog because i think it does not accept template_name as an attribute anymore.

LMK if you have further problems but i think that you should start looking at the API documentation here. The current implementation tries to be the more compliant as possible to the api.
