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 VMware.pm. It would be great for the community to start researching this and designing the code to handle dynamic vlans.
