As with anything in VMware there is the right way to do something and the wrong way to do it... or rather, there is the I slapped this together and it works way (the wrong way) or the best practice wont give you any trouble way (the correct way). So I am going to focus on right way to setup the Software iSCSI initiator setup in vSphere 4 with this post; yes it is true that you can simply right click the SWiSCSI device in vCenter (or the VIC) and click enable and give it a target to discover, and that may work for a while... but in reality there is a more complex and correct way to set the SWiSCSI up. read more

XenClient Express

Recently Citrix released a product called XenClient Express (released in RC format). You can download it here: http://citrix.com/xenclient/download ; and yes it is free.

vSphere 4 - Keyboard Reboot Allowed by Default

I just encountered something scary, frightening and down right nerve racking about the defaults that are enabled on vSphere 4.
