How to run multiple simultaneous X Window sessions

If you share your Linux desktop machine with other users, you may occasionally need to switch from 1 X session to another. For example, you are busy writing code or blogging, and your spouse walks up to you and asks to 'quickly' check her email. You can log out so that she can login using her own account. But, the current context of your work is lost, and you need to re-establish it when you resume. A better way is to have her run a second simultaneous X session. The steps are as follows:

Enabling Predictive Cache Statistics (PCS) for Data OnTap 8.2p

* node1 is the controller currently primary to the aggregate/vol/LUN.
Step 1: Enable PCS
node1::> node run –node node1
node1::> options flexscale.enable on

It’s quite obvious that Nova-Docker driver set up success for real application is important to get on Compute Nodes . It’s nice when everything works on AIO Juno host or Controller, but  just as demonstration. Might be I did something wrong , might be due to some other reason but kernel version 3.10.0-123.20.1.el7.x86_64 seems to be the first brings  success on RDO Juno Compute nodes.

Oracle Solaris 11 Derived Manifest and modifying the boot system

This is a follow on from last last blog entry "Oracle Solaris 11 Derived Manifest with Automated Installation", where I mentioned that I could not examine the disk partitions of the new system since the aiuser does not have permission to run fdisk.

SmartDataCenter and the merits of being opinionated

Recently, Randy Bias of EMC (formerly of CloudScaling) wrote an excellent piece on Why “Vanilla OpenStack” doesn’t exist and never will. If you haven’t read it and you are anywhere near a private cloud effort, you should consider it a must-read: Randy debunks the myth of a vanilla OpenStack in great detail. And it apparently does need debunking; as Randy outlines, those who are deploying an on-premises cloud expect:
