In The Bag #10 – Week 8 2017

Welcome to the tenth edition of In The Bag!
This one comes a little late, it’s (barely) Sunday here, not Friday! Sorry about that, but I was “stuck” in a secure facility all week, doing a vSphere 5.5 til vSphere 6.5 migration.

  • osx-wificleaner
    Over time, we all accumulate a bunch of open networks that we’ve connected to — you do use a while connected to those, right? This little MacOS script will clean those right out of your network list, which is a good thing. For one, cleaning out those open networks makes sure your laptops doesn’t reconnect to them automatically, and secondly manually cleaning up that list is pretty tedious after a while.
  • VMware Technical Papers
    Handy little site that makes it easy to find those Technical Papers you’re looking for. Filter by product and read your heart out.
  • VMware IOInsight
    Nice new Fling from VMware Labs. Ever wondered how your VMs IO characteristics are? Well, IOInsight will give you that, erm, insight in a web based GUI.
  • How I Ruined Office Productivity With a Face-Replacing Slack Bot
    And people say slackbots are useless.


VMware vSphere 6.5 PSOD: GP Exception 13

While at a customer site, migrating an old vSphere 5.5 environment to 6.5, several hosts suddenly crashed with a PSOD during the migration. Long story short, we got hit by this: VMware KB 2147958: ESXi 6.5 host fails with PSOD: GP Exception 13 in multiple VMM world at VmAnon_AllocVmmPages (2147958)

It turned out that a bunch of the VMs we were vMotioning from the old environment had the cpuid.corePerSocket advanced setting set in the .vmx file, and this can cause ESXi 6.5 to enter a state of panic, and in our case it certainly did.

Upgrading the hosts to 6.5a, like the knowledgebase article states, alleviated the issue and we did not experience PSOD’s again while migrating the 100+ VMs from the old environment to the new one.
