Comment 36 for bug 1045027

I am not sure if this is caused by different CPU, I have almost exactly the same setting on another laptop (Thinkpad T61, CPU T7500 64-bit Ubuntu Raring), the KVM quest runs without any problems. But the same setting on the laptop with CPU T2300 32-bit Ubuntu Raring, KVM just pauses.

the following are the logs from the 32-bit T2300 laptop:

W: kvm binary is deprecated, please use qemu-system-x86_64 instead
char device redirected to /dev/pts/2
KVM: entry failed, hardware error 0x80000021

If you're running a guest on an Intel machine without unrestricted mode
support, the failure can be most likely due to the guest entering an invalid
state for Intel VT. For example, the guest maybe running in big real mode
which is not supported on less recent Intel processors.
