[Engine-devel] Things to be done to support Ubuntu hosts

Hi,
Recently Ubuntu support is added to VDSM, and .deb binray packages can
be downloaded from launchpad.net PPA [1]. Most of the key features such
as storage management and VM lifecycle work on Ubuntu. The cross
distribution network management patches are upstream as well. One big
piece left is making ovirt-host-deploy support Ubuntu, so that we can
manage Ubuntu hosts from Engine, thus close the gap on host side.
In May 2013 I made some hacks to ovirt-host-deploy and otopi. I made it
skipped parts not supported on Ubuntu and configure the environment
manually, and successfully added Ubuntu host to Engine [2].
Unfortunately I have no plans to continue on it, but I'd like to make a
summary of the things I hacked to help anyone who wants to submit
patches in future. I was to add a WIKI page but I found there were not
many items, so a mail would be enough.
1. Package management operations
Both otopi and ovirt-host-deploy query for dependency packages and
install them on demand. The otopi package management just supports yum,
we need to add apt-get support. Package names are different in Ubuntu,
so I made a list mapping the names. The list in in VDSM source
directory, debian/dependencyMap.txt .
2. Network configuration operations
ovirt-host-deploy asks VDSM's configNetwork.py to create bridge network.
Cross distribution support patches for configNetwork.py are under
review. ovirt-host-deploy supports Ubuntu bridge configuration as long
as they are merged.

[2] http://www.ovirt.org/images/5/57/Shanghai-VDSM-on-Ubuntu.pdf
Here goes the detailed hack patch. The hack was base on v1.0.1, I
rebased it to the latest master. The rebased patch are not tested. If
you find this email useless, it's actually a good news, which means
there is not a lot of work and problems ahead ;-)
Hack patch for ovirt-host-deploy.
