Public bug reported:
Hi,
The host processor is a 64 bit processor (as below)
When I run the emulated mode of 64 bit (full emulation) I can run the
64 bit OS fine. when I start using -enable-kvm, I get error message that
"Your CPU does not support long mode. Use a 32bit distribution."

Because you're using a 32-bit OS in the host.

I tried this
kernel uname: 2.6.32-5-amd64 #1 SMP Sat Jul 24 01:47:24 UTC 2010 x86_64
with version 0.12.5
when tried to use -enable-kvm the system starts out in the 32 bit mode rather than 64 bit. kvm version:
------------------
filename: /lib/modules/2.6.32-5-amd64/kernel/arch/x86/kvm/kvm-intel.ko
license: GPL
author: Qumranet depends: kvm
vermagic: 2.6.32-5-amd64 SMP mod_unload modversions
parm: bypass_guest_pf:bool
parm: vpid:bool
parm: flexpriority:bool
parm: ept:bool
parm: unrestricted_guest:bool
parm: emulate_invalid_guest_state:bool
this problem is still present.
Even if I use qemu-system-x86_64 I am able to run the 64 bit OS only if -enable-kvm is avoided but
the system is very slow.

You're host kernel is 64-bit? Please show the full command line you use
to launch qemu.

oops
I made a mistake
there were old binaries left out.
It is working fine now.
