Virtualbox on my Intrepid AMD64 only offers 32bit virtualisation

[jarl]

When I create a virtual machin in virtualbox OSE, it apparently only creates a 32bit machine. Nowhere in the settings can I see the CPU architecture of the virtual machine, however when I try to install ubuntu-server AMD64 on it, the boot CD complains "This kernel requires an x86-64 CPU, but only detected an i686 CPU. Unable to boot - please use a kernel appropriate for your system.

Why does virtualbox on Intrepid 64 bit not support 64 bit guests?

Some say that you should enable virtualization and PAE support to be able to run x64 OS. However that didnt help me.

I have this issue on one of my 64 bit hosts, it must be something with the processor but I do not know what.

What version of virtualbox are you using ? OSE or PUEL ? what version ?

Also I believe you must be running x86_64 on the host as well (Just checking).

It didn´t help me either.

Yes, my host is AMD64. Good point, I didn't mention that explicitely in my initial post. More precisely it is (from /proc/cpuinfo)
vendor_id : AuthenticAMD
cpu family : 15
model : 36
model name : AMD Turion(tm) 64 Mobile Technology ML-40
stepping : 2
flags : fpu vme de pse tsc msr pae mce cx8 apic sep mtrr pge mca cmovpat pse36 clflush mmx fxsr sse sse2 syscall nx mmxext fxsr_opt lm 3dnowext 3dnow up rep_good nopl pni lahf_lm

I am using virtualbox-ose 2.0.4. What is PUEL?

PUEL = the version you DL from Sun. I suggest you try that version.
