Your system does not support long mode
Just a quick note for anyone who may come across a similar issue when trying to deploy server images on to their VMWare environment. I've been lucky enough to get a new server recently to test various virtual WLCs and management packages that are being put out by various wireless vendors. But after installing ESXi and deploying a couple of server images, when I tried to start the virtual servers up, I kept getting the following messages popping up in vShere: (For search engine benefit: This virtual machine is configured for 64-bit operating systems. However, 64-bit operation is not possible. Longmode is not possible. Longmode is disabled for this virtual machine ) Also, in the console of the server (Cisco MSE & NCS), I was getting the following reported: " Your CPU does not support long mode. use a 32 bit distribution " I was concerned that maybe there was an issue with my server CPU, in terms of support for virtualization. I rebooted the server
