Subject [jira] [Created] (CLOUDSTACK-353) Add support for virt-sysprep for template creation (and possibly VM deployment) on KVM
Date Mon, 15 Oct 2012 23:25:02 GMT
Kirk Kosinski created CLOUDSTACK-353:
----------------------------------------

             Summary: Add support for virt-sysprep for template creation (and possibly VM
deployment) on KVM 
                 Key: CLOUDSTACK-353
                 URL: https://issues.apache.org/jira/browse/CLOUDSTACK-353
             Project: CloudStack
          Issue Type: Improvement
          Components: Hypervisor Controller, KVM, Template
    Affects Versions: pre-4.0.0
            Reporter: Kirk Kosinski
            Priority: Minor


On KVM, the virt-sysprep utility can be used to generalize a Linux VM disk image. In RHEL
and Ubuntu, this tool is included in the libguestfs-tools package and the man page is here:
http://libguestfs.org/virt-sysprep.1.html

It would be useful if CloudStack could run virt-sysprep during the process of creating a template
from a KVM VM. Such an option could be added to the createTemplate API and as a checkbox in
the UI, and the person creating the template would not need to manually perform the tasks
handled by virt-sysprep. Additionally, it might also be useful to have the option of running
this tool on a VM immediately prior to booting it for the first time after deploying it, since
someone might want or need to use existing templates that have not have been properly generalized.
