Didn't i say that i have no means of testing it? Even x86 box yields:

~$ uname -a
Linux laptop 2.6.31 #7 SMP PREEMPT Sun Sep 13 10:59:44 MSD 2009 x86_64 AMD 
Athlon(tm)64 X2 Dual Core Processor  3800+ AuthenticAMD GNU/Linux
~$ egrep '^flags.*(vmx|svm)' /proc/cpuinfo 
~$

Help is needed with that.

And yet you still enable kvm.. sigh..

And somehow the above failed to impress and suggest that loadvm wouldn't work?
