I am using VirtualBox on a Ubuntu 10.04 64bit host. I would like to install a Fedora 64bit guest.

When I try to run the 64bit live cd, it says "Automatic boot in 10 seconds..." after which I get a blue background with no menu options. I am familiar with Ubuntu but not Fedora.

I have been able to install a Fedora 32 bit system just fine.

Any suggestions? I am trying to run an rpm that won't run in Ubuntu even using alien.

update I tried to install from the full distribution (non-live) DVD image, and the installation stopped with the error

this kernel requires an x86-64 CPU, but only detected an i686 CPU

However, the results of uname -a indicate that my host is x86-64:

user@desktop:~$ uname -a Linux user-desktop 2.6.32-26-generic #48-Ubuntu SMP Wed Nov 24 10:14:11 UTC 2010 x86_64 GNU/Linux

Have I configured VirtualBox incorrectly?

Can you please provide the exact model of your Processor?

because some processors don't give you access to 64 bit Modes in virtual machines, even though its supported on the host ...

Also, please make sure that you have the Intel VT-X mode (assuming its an intel CPU) enabled in the BIOS settings on the host ...

Awaiting your update :)

  • its most likely the lack of VT-X that's causing the problem IMO

  • @JourneymanGeek based on the screenshot, it appears that VT-X is enabled

  • @David you're still having this error? as per this link: ark.intel.com/products/33911/… your CPU supports 64 bit mode along with VT-x .. check is you have the extensions and the support enabled in the virtual machine options, that's the only culprit that remains for this error to occur

  • I would have to try this again, but I don't think it is worth trying to reproduce the error at this point, almost 1.5 years later.

double check md5 or sha hashes of downloaded ISO/CD with the originals

  • sometimes .iso file or CD is corrupted (during download/ burning). The place you downloaded Fedora should be a file with checksums. You can calculate the checksum for your downloaded .iso and compare it with that sum on the site (even better if you compare with checksum from original Fedora site). The same is for CD (if you install from CD). If the sums are equal - file is transmitted correctly, if not - download again

  • .. okay, I'll try to download the torrent from torrent.fedoraproject.org since the Transmission will do the checksum for me. will let you know how this goes
