In part one of his series on developments with LDoms Stefan Hinker discussed the basic concepts of LDoms and how to configure a simple control domain, including a demonstration of how resources are put aside for guest systems and what infrastructure that calls for. In part two Hinker shows how to create a guest domain as simply as possible using one core's worth of CPU, one crypto unit, 8GB of RAM, a single boot disk and one network port. Hinker creates the network port by attaching a virtual network port to the vswitch that was created in the primary domain. For the boot disk, we'll need two things: A physical piece of storage to hold the data, called the backend device in LDoms speak. And then a mapping between that storage and the guest domain, giving it access to that virtual disk. For this example, we'll use a ZFS volume for the backend. In a later article Hinker promises to discuss what other options there are for this and how to chose the right one. Code samples and screen shots accompany the article.
