[Qemu-devel] [Bug-Report] KVM failed to support netbsd-based kernel!

[GaoYi]

Hi all,
   I am running a netbsd kernel in KVM, using Intel VT. However, the OS failed to start up with the following outputs:

    KVM internal error. Suberror: 1
    emulation failure.

   The software configuration is: QEMU-KVM-1.1.0, kvm-kmod-3.3 and linux-2.6.32. So what does this failure report mean and how can I locate the unsupported line in the guest kernel.

   With kind regards,
