Hello again, status update incoming!
This week I started working on VMBuilder, which is one of the more important
components of the project. For those who aren't informed, VMBuilder is a quick
and easy way to build images for various kinds of virtual machine environments.
The stock 0.11 trunk supports ec2, xen, and ubuntu; Bzed maintains a Debian
branch which supports etch currently. So I got ahold of those, put 'em in a Git
repository[1] and started working.
The Debian support plugin had a bug with Xen support I fixed up; it was trying
to grab Xen-compatible kernel packages by querying rmadison for a package named
"linux-image-xen". This works fine for Ubuntu, but doesn't work on Debian
because we call it "linux-image-2.6-xen-<arch>". So I changed the way it looks
for kernels. Of course, now it won't work on Ubuntu, since the code isn't
telling rmadison to check Debian specifically yet. (In a particularly grevious
episode of idiot ball holding, it took 30 minutes of checking before someone on
IRC reminded me that there is no "linux-image-xen" package in Debian.) Will
have to get ahold of Bzed and ask him if he wants the patch once I can find the
guy's email address.
I started building ec2 support into his plugin by looking over the ec2-specific
functions from the Ubuntu plugin, seeing what each line does in the Ubuntu
plugin and checking if Debian needs it. Currently I'm working on the etch.py; a
lenny.py has yet to be written but I suspect it's not much different. I should
talk to Eric Hammond sometime, since he deals with building AMIs alot.
As a side note, VMbuilder also currently won't be able to upload or register
AMIs on Eucalyptus since it currently just tries to connect to AWS. Something
else I will have to fix.
To sum it all up, for the next bi-weekly period, I plan to do the following:
* Get VMbuilder pumping out Debian Etch and possibly Lenny AMIs.
* Get ahold of Bzed and coordinate development of the vmbuilder-debian branch.

My Git repo for the VMbuilder work. Feel free to git-clone and play with it.
