I can't install windows 64bit on Virtualbox headless

  • 772

I'm trying to install Windows2008r2 64bit on a Ubuntu 12.04 64bit host. After created the VM (with --ostype windows2008_64 I boot up the installation iso but windows says:

Attempting to load a 64-bit application, however this cpu is not compatible with 64-bit mode

I did --vtxvpid on but nothing changes.

Output requested

# uname -i
x86_64
# grep flags /proc/cpuinfo | head -1
flags           : fpu vme de pse tsc msr pae mce cx8 apic sep mtrr pge mca cmov pat pse36 clflush dts acpi mmx fxsr sse sse2 ss ht tm pbe syscall nx lm constant_tsc arch_perfmon pebs bts rep_good nopl aperfmperf pni dtes64 monitor ds_cpl vmx est tm2 ssse3 cx16 xtpr pdcm dca sse4_1 xsave lahf_lm dts tpr_shadow vnmi flexpriority

What I have to verify?

  1. note that you can't virtualise 64 bits in a virtualised environement, you will have to virtualise in 32 bits, Also make sure that you have virtualization enabled in your bios cpu settings, and that your CPU actually supoprts virtualization
