I've installed QEMU (qemu-kvm-0.12.3) on my VMWare guest 'Ubuntu 10.04LTS' system, which all runs on a physical SONY VAIO x86-64 Intel laptop. Although not relevant, the VMWare host system is Windows 7.

When I execute 'qemu linux-0.2.img', the output is

open /dev/kvm: No such file or directory
Could not initialize KVM, will disable KVM support

I've confirmed that /dev/kvm doesn't exist.
I've confirmed that hardware virtualization is enabled in my VAIO BIOS.

Other posts have indicated I should do a 'modprobe kvm-intel'. When I do this, I get the following error message =>

FATAL: Error inserting kvm_intel (/lib/modules/2.6.32-38-generic/kernel/arch/x86/kvm/kvm-intel.ko): Operation not supported

The output from 'lsmod | grep kvm' is the single line

kvm 245573 0

The output from command 'cat /proc/cpuinfo' is

Since the /proc/cpuinfo listing doesn't mention 'vmx', does this mean that QEMU (or KVM) will not function while running on a VMWare Ubuntu guest?

Any suggestions on how to resolve this are appreciated.

I don't think you can run KVM inside a KVM guest, and the error message seems to confirm my belief.

But I think you can run the QEMU emulator without acceleration.

Will look into this.

you are running vmware, and in it, you are trying to run kvm. Even if vmware provides nested virtualization (I think that appeared only in WS8), nobody will say for sure, that the way vmware nests the VT and VT-d instructions fits anything but another instance of vmware.

If you want to try kvm, it would be best to install it on the laptop itself
