While trying to install ubuntu 13 on windows 8 host, it throws the error "this kernel requires an x86-64 cpu but only detected an i686". However, mine is a new dell xps 8700 with haswell i4770 and I verified virtualization is enabled in bios. What could be going wrong?

    Sounds like you are trying to run 64-bit guest operating system on a 32-bit host operating system. What product you have exactly. Certain Haswell prodcuts do not have the abiity to do that. – Ramhound Oct 16 '13 at 11:18
  • I thought dell xps8700 was only sold with windows 64bit. @Kiran: when you defined the new VM, did you check "Ubuntu 64bits"? – MariusMatutiae Oct 16 '13 at 11:25
  • @MariusMatutiae, You are right, I have not selected that option. Infact, I have not even noticed that option until you pointed out. Trying it out now. – Kiran Oct 16 '13 at 11:27
  • @Ramhound, it is running windows 8 in 64bit mode.. – Kiran Oct 16 '13 at 11:27
  • @MariusMatutiae, that is infact the reason. Post it as answer and I will accept it.. thanks – Kiran Oct 16 '13 at 11:29

When you define a new VM, you must check the "Ubuntu 64bits" option under the Version drop-down menu.
