Xenserver 6.2 to 6.5 upgrade notes

With 6.5 released we have started upgrading machines. Our initial upgrades were fairly straightforward and although the install of the Xentools was very slow and required numerous restarts it completed fairly well.

We have had issues with 2012 server running Exchange 2013 - insofar that we've lost the network adapter and can't get it back. The solution seems to have been to clone the VM and then remove and add the adaptor back in. The restart took a very long time and there were issues with the Xentools install not working properly and difficulties with getting it to upgrade. We ended up removing it and reinstalling it however that wasn't really optimal and we blew our outage window but quite a margin.

Before upgrading Xentools definitely take a snapshot of the VM if it's running Exchange. As we do more I will continue to update this site with more information.

Windows 10 Enterprise Eval - gotchas

After an annoying turn of events where my Windows 10 Enterprise USB drive failed, attempts to install Win10 onto a computer failed miserably. I turned to the net and managed to get my hands on Microsoft's Windows 10 Enterprise Evaluation. I have an enterprise key so I thought - cool! Here's the opportunity to get it going and to then upgrade the license later. Full install, patched etc and all is swell. Except when I try to upgrade. I straight up tried changing the licence key only to get a variety of errors, most of which are pertaining to the activation system being unavailable. The I try this: https://winaero.com/blog/upgrade-windows-10-evaluation-to-full-version-easily/ but it doesn't work either. Next I'll try this: h ttp://www.edugeek.net/forums/windows-10/174594-upgrading-windows-10-enterprise-90-evaluation-full.html And if all else fails, in goes the bootable USB I've now created. If only I'd had this in the first instance I would not be writing t

Plone - the open source Content Management System - a review

One of my clients, a non-profit, has a lot of files on it's clients. They need a way to digitally store these files, securely and with availability for certain people. They also need these files to expire and be deleted after a given length of time - usually about 7 years. These were the parameters I was given to search for a Document Management System (DMS) or more commonly a Content Management System (CMS). There are quite a lot of them, but most are designed for front facing information delivery - that is, to write something, put it up for review, have it reviewed and then published. We do not want this data published ever - and some CMS's make that a bit tricky to manage. So at the end of the day, I looked into several CMS systems that looked like they could be useful. The first one to be reviewed was OpenKM ( www.openkm.com ). It looked OK, was open source which is preferable and seemed to have solid security and publishing options.

Fixing a black screen after doing a Kali Linux update

Kali Linux is a rolling Linux distribution designed for security and penetration work. You can find details on it here: www.kali.org . We run this excellent product for a range of different security work and it's been great. I built the image in VMplayer, then shared it to the team and we've all been at it since. A recent update broke it though - black screen, no network and completely unresponsive. There are lots of posts about similar things - mostly to do with graphics adaptors, however, we found that executing the following at a root prompt fixed it. But how to get to the root prompt from a blank screen? Linux has a number of terminals available to the user - most of us use the graphical one to do our day to day, but you can access a command line prompt without much trouble. Simply hold CTRL-ALT and then F2 or F3 down at the same time and it drops you to a command line login. BOOM. Time to fix it up. For me, and for the other fellas in the team, all it too was to
