Hello could you help me on running kvm on my via nano u2250 processor stepping 3?

[Timothy McDaniel]

here is my /proc/cpuinfo

power management:

also here is my uname -mrs
Linux 3.2.0-4-amd64 x86_64

here is uname -a
Linux sd-24793 3.2.0-4-amd64 #1 SMP Debian 3.2.63-2+deb7u1 x86_64 GNU/Linux

please tell me if you need anymore info on helping me get kvm to work.

Last I was aware, Via's implementation of vmx was broken.  I'd guess
that's still the case.  Thanks,

Yes, there are many reports of this:

https://bugs.debian.org/cgi-bin/bugreport.cgi?bug=570244
http://www.mail-archive.com/kvm@vger.kernel.org/msg11662.html
https://bugs.launchpad.net/qemu/+bug/712416

Can you try running vmxcap (scripts/kvm/vmxcap in git://qemu.org/qemu.git)?
