Hi Everyone,
I am relatively new to libvirt community; have worked on it from last half year
mostly towards adding few missing APIs especially for ESX driver. One of the
features I worked was installing a domain (VM) using OVAs. It is been a long
time OVA became defacto standard for distributing and installing Virtual
Machines, but surprisingly libvirt does not provide support for it. I wanted to
perform a quick sanity int the community so that I am not stepping on anyone
feet here. So far, I have working code, but to contribute upstream would
require a bit of a cleanup work.
One of the concern that I intend to get inputs on:
OVA is a tar format archive, the first pre-requisite is to parse OVA and get
following information:
1. XML descriptor.
2. VMDKs for transfer after domain is created on the hypervisor. (in ESX world
that is done by getting a lease object and then transmitting the disk bits to
hypervisor)
I am wondering, where should I put the common code to parse OVA? My initial
thought is to enhance conf/domain_conf.* file, given it already provides
parsing routines for XML descriptor. Waiting for your feedback on this one.
As I am familiar with ESX libvirt interaction, so the immediate plan is to
enhance ESX driver, hopefully in near future will contribute the same feature
to KVM/Xen etc.
Thanks!
Ata
