Thoughts on the VMware Code Leak

April 25, 2012 by Bob Plankers

VMware has confirmed that there was a theft of the ESX source code around April 8th, 2012. I have some non-linear thoughts on this whole thing. First, the code is from 2003 & 2004, and for ESX. ESX was the big, bloated hypervisor that shipped with whole Linux installs, and the purported 300 MB of source code sounds like they might have code for a lot of the Linux utilities that shipped with. So what? The newer version is ESXi which forgoes the Linux install in favor of being very small. That said, I’m going to assume they have the source code for the base hypervisor itself. I’m also going to assume that some of the hypervisor code from then …

How to Change SCSI Controllers on your Linux VM

A question from Matt Vogt prompted this, where he wants to go from the BusLogic SCSI controller to the LSI Logic SAS controller. It’s actually a straightforward conversion if you have the right steps. This is based on Red Hat Enterprise Linux 3, 4, and 5, but the principle should be the same for everything. It’s basically: snapshot, change config files, change hardware. Red Hat Enterprise Linux 6, in contrast, appears to have all the LSI Logic, parallel & SAS, drivers, as well as the paravirtual SCSI drivers, so all you need to do is shut the VM down and change the type of SCSI controller you’re using. I always recommend trying this on a test VM before you try …
