Early Monday Turtle Blogging

I got a bit carried away this weekend on other projects (mostly reading, with a side of biking), so here is an early morning dose of turtle love for this Monday.

e1000 vNIC’s Hate Me – How To Find And Change vNic Types With The VI ToolKit

Well, this being the third time I’m trying to write this post (some issues with my Wwindows 7 VM, something to be said for autosave).

Sunday Turtle Blogging – Meet JeOS!

JeOS! Pronounced “Juice”. What a concept. Isn’t it? JeOS is still a relatively new concept in the virtualization scene. Build an appliance with “Just enough OS”. As it’s a relatively new concept, I’ve got a relatively new turtle (two actually, but you’ll meet the other later). Meet JeOS: JeOS is a Red Eared Slider, all

Bad Things Happen at 2am – How To Resign a VMFS Partition

Well, it started at midnight, a standard hardware upgrade really. Power down the VM’s, shut down the host, and call the DC team to do their thing. Twenty minutes later, got a ring from the DC, that the upgrade had been completed. I popped open the VC, and well, there was no local storage. It

Where Did I Put My Tools? Are They In Sync? – Checking the VMware Tools with PowerShell

It’s 7PM, do you know where your VMware Tools are? Rather, do you know if all your VM’s have them installed and running? Here is a one-liner to check that with PowerShell: get-vm | where { $_.PowerState -eq "PoweredOn" } | Get-VMGuest | where { $_.State -ne "Running" } | select vmName, State What this
