vSphere Web client and high DPI displays

vSphere Web client and high DPI displays

I bought brand new DELL XPS 15 with High DPI screen – 3200 x 1800. Obviously, daily work with this resolution without changing size for icons and fonts and other items,would not be possible on a long distance :-). When I finished initial configuration of Dell XPS 15 I downloaded latest patches for Windows 8.1 – after few reboots laptop was ready to work. All apps works just fine and displays content correctly: web browsers...

PowerCLI script to report and change host NTP settings

PowerCLI script to report and change host NTP settings

The script I would like to share today is in a way supplementary to what I wrote about in my previous post. For those who don’t know it yet – last week I gave an example of completely turning off VMware Tools guest time synchronization via script that is able to set any of virtual machine “advanced settings”. Now I would like to look at subject of timekeeping from vSphere host perspective, I think we all agree...

Script to disable time synchronization in VM… and more!

Script to disable time synchronization in VM… and more!

Time synchronization of Guest OS-es running vmware virtual machines is a very important topic that has been extensively covered in VMware documentation. General recommendation for all types of OS-es is to use external (NTP) time source and not to use VMware Tools time synchronization (with vSphere host) whenever possible. There are many good reasons for that, including but not limited to reduction of CPU overhead when using external time...

Set current system time on vCAC appliance

After so many deployments of vCAC  I’m still finding some strange issues and misconfiguration. This time I had a problem with log in to tenant portal after full power cycle of my vCAC environment.

How to manage PSA claimrules and SATP rules with esxcli

How to manage PSA claimrules and SATP rules with esxcli

I will not try to explain PSA here, there is enough resources to read about it (if you asked me for recommendation I’d suggest Cormac Hogan’s excellent blog) and I don’t feel expert enough to “increase entropy” on that subject. Instead I’d like to focus on what used to be particularly confusing to me: the claimrules, SATP rules and how to manage them with esxcli. PSA behaviour can be controlled with two...

PowerCLI script to report Guest OS disk usage

PowerCLI script to report Guest OS disk usage

Anybody can have a bad day, some people claim it is best to clean one’s desk on a day like that, but I personally prefer to chase customers of my virtual infrastructure for resources they are ab-using. On many occasions projects request a lot of disk space for their virtual machines and then under-utilize these disks which is just “not cool”, especially if they require thick provisioned vmdks (which I always prefer for...
