Thread-topic: Intel VT-x for HVM

Hi,

I am using HyperPlatform(https://github.com/tandasat/HyperPlatform), which needs Intel VT-x and EPT technology, so I create a Windows 7 virtual machine on Xen with following configurations(see https://wiki.xenproject.org/wiki/Nested_Virtualization_in_Xen):

hap = 1

nestedhvm = 1

And use Coreinfo(https://technet.microsoft.com/en-us/sysinternals/cc835722.aspx) to check VT-x and EPT, it shows the system supports Intel VT-x and EPT:

sc start HyperPlatform

The virtual machine hangs and screen is broken:

The guest is “Windows 7 x64 SP1”, host is CentOS-6.5, kernel-4.4.43, Xen-4.8.0.

Anyone can help? How to support Intel VT-x for HVM?

Thanks

-Kangjie
