instance_template_name does not work for vmware driver

[zhu zhu]

Currently vmware driver will adopt uuid for instance names. This will lead two problems:

1) instance name template will not apply for vmware driver. But it will display instance name with nova show command. It will be misleading.

[root@cmwo cmwo]# nova show temp-vm-host1-99

2) This uuid is not user friendly for VM names.

Is this line 'OS-EXT-SRV-ATTR:instance_name | instance-000000ec' need replace instance name 'instance-000000ec' with temp-vm-host1-99? I may find same problem in my driver.

I am not sure why currently id is used for VM instance name on vCenter. But if change from id to template_id may cause many of vmware integration code modification. I think better approach is modify vmware integration doc adding this situation. If required adding template id to VM description or tag on vCenter VM.

    Add vCenter driver instance name section

    Add instance name section to VMware configuration reference.
    KVM use instance_template name but VMware vCenter driver
    use instance ID.
