Ok, I also downloaded the 64-bit version of Ubuntu 9.04 Jaunty (the daily current build) and also got a kernel error that said something about a 64-bit kernel not being able to be run.
Someone please check me, but a /proc/cpuinfo on my system produces the following: Code:
processor : 0 By all counts, I would think I had a 64-bit processor and running the 64-bit version of VBox, thus able to run 64-bit OSes in a vm. What could I be doing wrong? |
Solved
I figured it out. There is a setting in the BIOS for VT. That was disabled. I enabled it and it now allowed me to install Ubuntu Jaunty 9.04 (current build) after a cold boot. I haven't tried Win7Beta 64-bit yet, but I was getting a similar error with Jaunty so I suspect the setting change in the BIOS is the key.

Windows 7 x64 beta on VirtualBox 2.1.2 under Ubuntu 8.10 x64
I have a T61P and installed Ubuntu 8.10 Intrepid Ibex x64 on it with no issues. VT was enabled in the BIOS before I began the install.
I installed the newest VirtualBox v2.1.2. I chose Windows 7 x64 and used the default settings. VirtualBox gave the same error message others have reported seeing. I then changed the machine settings to "Server 2008 x64" and rebooted the VM to the Windows 7 DVD and this time it got all the way to starting setup with no problem. I shut down the VM and changed the machine settings back to Windows 7 x64. This time it booted and installed with no issue. Go figure... |
Ubuntu 64bit VirtualBox 64bit but no Windows 7 64bit :(
I'm having the same issue here with Ubuntu 64bit. Ive tried most possible combinations of settings in VirtualBox but to no avail.
Perhaps the problem is deeper? |
