Opennebula And Qemu-kvm not standart

Hello. Help me, Please.
I have problems with start qcow2 image on opennebula.
I have 2 servers with opennebula, but different hardware.
First server:
If I write on terminal:
kvm -no-kvm -m 512 -hda /vm/MY.QCOW2
qemu-kvm -no-kvm -m 512 -hda /vm/MY.QCOW2
That’s allright.
If i write on terminal:
kvm -m 512 -hda /vm/my.qcow2
qemu-kvm -m 512 -hda /vm/my.qcow2
Not work.
And this qcow2-image does not work on nebula on Firefox server… ((
This image is work on second server on opennebula.
How I can start this image on opennebula with parameters -no-kvmon Firefox server.

Excuse me, Please on my bad english.

The problem seem to be your hardware that does not support virtualization. You can use this article to check if that’s the case:

I don’t recommend you to use OpenNebula + kvm without virtualization support.
