[dts] [PATCH] framework: add virt_type option for virt type(kvm/libvirt) selection

[Liu, Yong]

Hi Herbert,
I think argument "virt_type" is not needed for suite level configuration. There will be one possible scenario like libvirt and qemu VMs enabled in one suite. 
Please see my inline comment. 

Thanks,
Marvin

Virt_type has been specified when instantiating virtual machine object, so can initialize virt_type variable in init function of VM object.
