Finding the SmartCloud amidst the fog
IBM don't provide ready-to-go vanilla virtual images for SCP / HSLT which means everyone will be rolling their own... While doing this you probably follow the guide to create a RHEL based image (yes only RHEL is included in this step by step walk-though - probably because this is what the Image Construction and Composition Tool requires).
OK, so now you've created your Red Hat Enterprise Linux Virtual Image to be used with HSLT and you're ready start deploying some instances. You deploy a couple of instances and start loading some software. Pretty soon you find that the OS is seriously out of date and hasn't had a "yum update" done - ever... Of course you would need a RH subscription for that. Enter CentOS... CentOS is based on the RHEL code base but there are some tricks you need to know about to get it to work as a Virtual Image under SCP / HSLT.
The first CentOS image I created and imported into HSLT wouldn't start from the IWD. I then read somewhere that the install DVD determines how closely the install of CentOS resembles RHEL so I changed my install from the LiveDVD to the DVD labeled "CentOS-6.3-x86_64-bin-DVD1.iso". This time the Instance started OK.
If you need an image pronto let me know and I'll share it with you. You'll need to do "yum update" yourself but at least this is possible without a Red Hat subscription. Image is CentOS 6.3 64bit. Also have a RHEL 6.3 - 64bit image available if needed - not sure why IBM hasn't already built some of these already for HSLT...

I'll post later with steps to create a CentOS image and any helpful additions to the standard steps to help you and users to get going more quickly...
Will also be attempting a Windows image creation soon...
