Nostra-Daniel once pontificated that memory is like stacking penguins on an island. Each thing you’d like to remember is a penguin, as you fill the island, you have to choose which penguins end up in the ocean. For me, setting a static IP on Ubuntu was one of those penguins that ended up being fed[…]
Perhaps it’s just been a while since I’ve needed said floppy image, but I recall a time when you had to search the VMware KB to get the XP LSI driver. Well, today while changing some of my lab VMs over to PVSCSI, I found that the needed floppy images are in “/vmimages/floppies/†(at least[…]

Thus reverting it, will also revert this settings. Because I was under the opposite impression, I[…]
Ran into an issue today where my vCenter would not come back up after a reboot. Standard troubleshooting ensued… the DB is up, it is accessible, odbc is Kosher, etc. At that point, Windows helpfully popped up a message balloon: “I pity the fool who runs outta disk space!†So I dug, and a dug…[…]
We’ve covered snapshots here a few separate times in past. However most of these were focused on ESX classic or preforming the work using one API or another. As VMware is making the shift to ESXi, it makes sense that you will need a way to deal with snapshots from the ESXi console (aka TSM/Tech[…]

While this isn’t as big a problem as it used to be, Context Switches in applications can still bring a VM to it’s knees. In this post I’m going to link you to some resources as to what context switching is, how to look for it, and why excessive context switches hurts performance. What Is[…]
The version of Likewise-Open that ships with VMware’s vMA is a bit old, and for one reason or another, it may need to be upgraded outside the normal window for upgrading the vMA bits.
