Hi Andres, thanks for taking times to answer my questions. Regarding the limitations, I was looking for intel documentation indeed, not the maas one as I assumed that maas didn’t hardcoded anyone. So, if you’ve got some links to share I’m all in :-)
About my question regarding the ressources aggregates. I didn’t get it. How is this supposed to work? Does RSD systems are provided with a specific OS/hypervisor dedicated to create VM that can be hosted on two different hosts but still be seen as a unique ressources within the guest OS? Is that using MPI under the hood? How can I create a node that will address ressources across multiple physical machines? Thank a lot again!
