Yes, but with limitations. Also this is more related to your local
networking setup and the individual provisioning modules.
Today VCL does not dynamically create/destroy vlans when needed. I
think this is needed in the long-term - at some solution at a
localized level - i.e. within a DataCenter.
To make it work in the current code - You would need to have the
required vlans setup and preconfigured in your hypervisor, if using
xcat in your ethernet switch modules(ESM).
In the image table there is a column called project. At NCSU we use
this project variable to define special vlans that have been trunked
to the hypervisor or the ESM that the desired vcl image should be in.
Within a provisioning module, one can use the project variable to
define which network the vm should be a part of.
Note - there is not a globally defined VCL method for handling the
project variable. For example in the xcat module there is a routine
called _assign2project. This routine simply calls out the a custom
script (local to NCSU) to change the vlan assignments on the blade
port within the related ESM.
In the VMware/VMware.pm module it checks for and adds an existing
network by the project name to the vm. But the network name has to be
listed within the hypervisor. Look for $image_project in the
It would be great for the community to start researching this and
designing the code to handle dynamic vlans.
