Peter, You write: > the z/VM v6.3 documentation on OpenStack and XCAT is somewhat scattered and perhaps sparse ...
Hmm, yes, I would tend to agree with you. To confuse matters, I believe there is both an open source version of xCAT that you can install yourself, and now a pair of virtual machines (XCAT and ZHCP) built into z/VM. When I was still with IBM, I tried to get the xCAT developers to work with me to get it into "The Virtualization Cookbook". We had a few meetings and made some progress. In July 2012, there was "whitebook" flavor published as "z/VM and Linux on IBM System z: TheVirtualization Cookbook for z/VM 6.2, RHEL 6.2 and SLES 11 SP2". It's on the Web at: http://www.vm.ibm.com/devpages/mikemac/CKB-VM62.PDF Chapter 21 is on xCAT. Perhaps it will help (or perhaps it just adds to "scattered and sparse" :)) But remember - this chapter documents for the open-source flavor of xCAT, written before it was built into z/VM. -Mike MacIsaac On Tue, Jan 27, 2015 at 10:09 PM, Bishop, Peter <[email protected]> wrote: > Hi, > > Firstly a specific question: I believe that the disk pool used by XCAT > for its ISO images is completely different to the one used for housing the > data used by the cloned guests.
