My comment relates to module design rather than the mechanics of SVN.
The basic issue is that I have a module that works great in our VCL
infrastructure, but there are ways in which it could more easily integrate into
the overall design of the VMware provisioning module. To describe in brief, the
vCenter module is implemented as a subclass of the vSphere_SDK module. Since
the VMware module doesn't know a priori which API object to use, it iteratively
attempts to connect to a vm host using various existing APIs. When I wrote the
vCenter module for our system, I tried to touch the VMware module as little as
possible, so I ended up subclassing VMware.pm and modifying the definition of
$VSPHERE_SDK_PACKAGE (defined, instead, to load
The better approach, though, (and I would appreciate some feedback on this)
would be to add an additional class variable (e.g. $VCENTER_PACKAGE) and modify
the initialize subroutine in VMware such that if the vSphere module did not
connect, it would try connecting with the vCenter module. If that attempt
succeeds, the api object would proceed to use the vCenter module. Does that
sound like a reasonable approach? This would assume that the username and
password used to access vCenter were not the same as the credentials used to
access individual esx hosts. That is true for our setup, but is that something
we could reliably trust to be the case in other vm host infrastructures?
Also, there are some aspects of the vSphere_SDK module that do not rely on
VMware's vSphere API -- notably in how the *.vmx files are generated. The
vCenter module follows this approach, since when I wrote the module, I chose to
reimplement only what was absolutely necessary to make it work. There has been
some discussion on this list on precisely this point. I am certainly interested
in moving the vCenter code in that direction, but if the hope is to put the
vCenter code into the 2.3 release (i.e. by March), it seems more reasonable to
use the code that has over six months of testing time in a production
environment. I would be concerned about making significant code changes and
adding them to a VCL release without allowing much time to evaluate the
