[Kimchi-devel] [PATCH V5] [Kimchi 0/4] Issue #372: Add support to netboot installation.

[pvital at linux.vnet.ibm.com]

From: Paulo Vital <pvital at linux.vnet.ibm.com>

V5:
    * Improved the changes in API for source_media
    * Added two new test cases
    * Updated UI to reflect the changes in template API

V4:
    * Changed API of source_media to be a dictionary with type and path
    * Adapted source code to the new API

V3:
    * set network as third default option to boot order

V2:
    * Adapted patch to new template API (automatic detection of cdrom)

V1:

This patchset adds support in backend to create templates and guests to netboot
without setting a cdrom path or URL as image to install. Once created a guest
to boot via network, the guest will request DHCP/TFTP/(NFS/HTTP/FTP) network
installation servers to download the configured images and start the install.

To test, use the curl commands (look the parameters used):

$ curl -k -u test -H "Content-Type: application/json" -H \
"Accept: application/json" 'https://localhost:8001/plugins/kimchi/templates' \
-X POST -d '{"name": "test-netboot", "source_media": {"type": "netboot", "path": "/var/lib/libvirt/images/netboot"}}'
Enter host password for user 'test':
