Changing the hostname of a VM in VCloud DIrector using Chef's knife-vcloud plugin

Question

I am using chef's knife-vcloud plugin. https://github.com/astratto/knife-vcloud I am able to create a new vm, using an existing catalog with the given documentation by, knife vc vapp create MyorgVDC-Tier1 chefnode2 "Just Created node2" WhAtEvEr-Id-tO-bE-SeEn

When I start the vm it by default takes the hostname that is given to the catalog. I tried modifying it by knife vc vm set info --name ChefNewNode WhAtEvEr-Id-tO-bE-SeEn --vapp MyvApp_Chef centos I want to change the hostname as per the role of the machine. At present I see this output. How do I change the hostname of the machine?

[root@chefworkstation ~]# knife vc vm show WhAtEvEr-Id-tO-bE-SeEn Note: --vapp and --vdc not specified, assuming VM is an ID VM Name: ChefNewNode OS Name: CentOS 4/5/6 (64-bit) Status: running

Answer 1

We can achieve this by changing the guest computer name. Note that the VM must be turned off to change any guest customization.

Command to change guest computer name:

knife vc vm config guest <vm name> --vapp <vapp name> --vdc <vdc name> --guest-computer-name <guest computer name> --admin-passwd <root password>

Answer 2

The --name you are passing is the Chef node name, not the hostname. If you want to change the hostname, you'll need to write/use a recipe that modifies /etc/hostname and runs some commands to persist. For example: https://github.com/3ofcoins/chef-cookbook-hostname
