The greatest challenge to any thinker is stating the problem in a way that will allow a solution

Welcome to vBlog, a personal record of my techy tinkerings and particular ponderings.

I tend to focus on VMware virtualisation, and the interaction/automation of it using PowerCLI (VMware's PowerShell Snapin), but anything that I happen to stumble across that seems like it might be of use at a later date, may well get recorded here.

I also maintain vWiki, which was a predecessor to this blog. Wiki's are great for quickly recording snippets of info, but tend not to look that great; Blog's are better looking things, but seem to require more effort so that the posts/articles are accessible in their own right. As a result I tend to update both interchangeably as available time, and depth of thought, permit.

If you happen to find anything of use, or in need of correction please leave a comment. Knowing that my ramblings are of some use is a great reward; and similarly I'd hate to waste anybody's time by feeding them duff info.

Upgrading VMTools always seems like such an afterthought.  You get through the effort of upgrading your vCentre, and ESX’s without any service interruption, then are left with a load of VM’s with out-of-date Tools and little authority to take them down as part of the upgrade.  Plus if you’re faced with the drudgery of having to speak to all sorts of different people and departments, its the kind of task that is only ever on the back-burner.

I tend to try to upgrade machines during ad-hoc reboots, which isn’t always sensible (during an service incident for example), and requires you to remember (not always possible if you’ve been up most of the night due to young kids / over exuberant drinkage).

There is an often overlooked option that lets you automatically update VM’s during a bounce, the only problem is – how to set on all your VM’s and retain full use of your mouse wielding arm and eyes…? Continue reading →
