----------------------------------------
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.
