VirtualBox supports 64-bit guest operating systems, even on 32-bit From the VBox website (emphasis mine): 64-bit guests What you need to do is make sure you are setting up a 64bit Virtual Machine. I'm wondering if the download page saw that I was trying to download from a Windows client and swapped out the x86-64 version for i686? Otherwise I downloaded the wrong ISO.Ĭan someone please tell me what the right ISO is? I thought for sure the AMD 64-bit version would be exactly what I needed. So I downloaded to a Windows client, put the ISO on a flash drive, copied it over to my Ubuntu machine, and saved it locally. Here's the kicker: I downloaded the ISO on a Windows machine, because my Ubuntu machine (the one running Ubuntu Desktop 11.04 and hosting the VM-to-be) has crummy network connection. I am confident that this is 64-bit, however, as uname -m produces x86-64 in the terminal.and executing lscpu produces: Architecture: x86_64 Unable to boot - please use a kernel appropriate for your CPU.Įdit: That message makes me think that I have a 32-bit machine but am trying to run a 64-bit ISO. This kernel requires an x86-64 CPU, but only detected an i686 CPU. When I select that, I get an error message: When I try to start the VM I get a main menu, the first option reads Install Ubuntu. I have been trying all morning to find the right Ubuntu Server (12.04) ISO to use for installing an Ubuntu guest OS on my VBox VM.
