How to configure libvirt, so qemu-kvm support nested virtualization, virtual
machine installed operating system is
windows_7_ultimate_sp1_x64_dvd_618537.iso, configure libvirt xml file is as
follows:
<cpu mode='custom' match='exact'>
<model fallback='allow'>core2duo</model>
<feature policy='require' name='vmx'/>
</cpu>
or
<cpu mode='host-model'>
<model fallback='allow'/>
</cpu>
or
<cpu mode='host-passthrough'>
<topology sockets='2' cores='2' threads='2'/>
</cpu>
We install libvirt in centos 7, qemu-kvm version is:
[Root @ localhost libexec] # ./qemu-kvm --version
QEMU emulator version 2.6.0 (qemu-kvm-ev-2.6.0-27.1.el7), Copyright (c)

Above is the basic environment and libvirt configuration, but in this
environment to install the internal implementation of the following windows7
virtual machine kernel interface calls are as follows:
if (!FeatrueControlMsr.fields.enable_vmxon)
{
MyWriteFile(FileHanle, "Bios??????????????????\n",
strlen("Bios??????????????????\n"), &ReturnLen);
MyCloseFile(FileHanle);
KdPrint(("Bios??????????????????"));
return FALSE;
}
in conclusion:
Through this kernel interface to determine the result is: Bios settings do not
turn on virtualization
How to solve this problem? Hope to get your help.
thank you very much??_______________________________________________
