Alan Evangelista (https://github.com/alanoe) and I are willing to
implement the support to Network Boot to Kimchi guests.
This is the first approach [Part1] we are going to develop: The direct boot
When finished, we are going to send [Part2] that will cover DHCP/TFTP, etc.
-------
This feature aims to develop Kimchi's support to create Guest that will
boot over Network using Libvirt Direct Boot
Libvirt details: https://libvirt.org/formatdomain.html#elementsOSKernel
Kimchi related bug: https://github.com/kimchi-project/kimchi/issues/372
We see three major changes in Kimchi code:
1- Change Template creation and update (BACKEND)
2- Change Template creation and update (FRONTEND)
3- Change Guest creation (BACKEND)
Details:
1- Change Template creation and update (BACKEND):
Backend is going to wait for these new parameters (json) in
Template creation or update:
"netboot": {
"kernel": "<KERNEL URL>",
"initrd": "<INITRD URL>",
"kernelargs": "<COMMAND LINE FOR KERNEL>",
"repository": "<PACKAGE REPOSITORY>" (optional)
}
Steps:
src/kimchi/API.json -> change "templates_create" and
"template_update" to receive above parameters;
src/kimchi/model/templates.py -> change
"TemplatesModel.create()" to check if "netboot" comes to save data
properly
-> change "TemplateModel.update()" to check if
"netboot" comes and update data properly;
doc/API.md -> change to reflect new parameters;
src/kimchi/i18n.py -> add new errors if needed;
Other:
- Change templates auto tests if necessary;
- Change "VMTemplate" class in "src/kimchi/vmtemplate.py" in
order
to probe DISTRO and VERSION;
2- Change Template creation and update (FRONTEND):
Front-end is going to have following changes:
- Add new entry in 'Add Template' window: "Network Direct
Installation";
- Create new window to allow user to provide new four parameters;
- Change Template update window. Add new tab to change or add
network installation parameters;
3- Change Guest creation (BACKEND)
Here it is necessary to change the XML creation, so we need to:
src/kimchi/vmtemplate.py -> change "VMTemplate.to_vm_xml()" to
check existence of parameter "netboot", then change <os> element
properly.
Other:
- Change guests auto tests if necessary;
- Change xml (VMTemplate) auto test if necessary;
