I've copied the vcl-dev list on my response because it's the
appropriate place for VCL discussion.
The copying of the .vmx file to the image's golden directory when
capturing files serves no purpose. It will be removed eventually.
Creating .vmx files on the fly works well for us because it lets us
size the RAM dynamically for each VM based on the database's image
meta-data. Similarly, we can connect the networking differently for
different VMs based on meta-data (for example the virtual switches the
VM should uplink to)

Hi Brian,
We got most of our questions resolved. In your current esx.pm file,
you generate the .vmx file on the fly when loading images, but copy
the .vmx file into the golden image when capturing images. What's
the benefit of creating the .vmx file on the fly? Does it fit the
working environment better? Are there reasons behind it?
Thanks,
Peng

Hi Brian,
I got more questions when I read the code. Hope you are not bored
with my questions.
In the load sub, you always create the vmx file by yourself. But in
the capture sub, you copy (and fix) the vmx in use to the golden
image directory. This seems unnecessary at first glance. Is there
any specific reason?
You copy the vmdk and vmx files to /mnt/vcl/inuse/
$computer_shortname (i.e., $datastorepath4vmx), but ssh-copy the
flat.vmdk file to /mnt/export/inuse/... (i.e.,
$datastore_share_path). Will do they seem to be different
locations? How do the target blade access these locations? I guess
$datastore will be remotely mounted on the target blade. Is
$datastorepath4vmx also mounted remotely on the blade?
Thanks,
Peng
