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) 2003-2008 Fabrice Bellard
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设置没有开启虚拟化\n", strlen("Bios设置没有开启虚拟化\n"), &ReturnLen);
MyCloseFile(FileHanle);
KdPrint(("Bios设置没有开启虚拟化"));
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。
