Re: Reserve a cluster in VCL
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.

Re: Reserve a cluster in VCL
I think it can be an interesting project. I start to think that I probably can add the vlan support to my kvm provisioning module (which we discussed in other emails in vcl-dev mail list.) From the designer prospective, could you talk about how this dynamical vlan should work? For example, what kinds of machines should be under the same vlan or different vlans? The machines under different vlans, should they still be able to connect to each other through public network? Should we create different vlans for both public network and private network? Where we should put the create vlan function? In provisioning module, or in higher level of VCL code?

Re: VCL Bootcamp notes on creating base images
I appear to be sneaking up on it... However image capture failed again. I am enclosing an excerpt from the log. Not sure what the problem is but it appears that it found a vmdk when it didn't expect to find one. This may be due to my misconfiguration of the VMHost - local storage. I specified the Data Store Path to be /vmfs/volumes/datastore1/datastore and the Repository Path to be /vmfs/volumes/datastore1/repository and created those directories.
