[Xen-users] 答复: Intel VT-x for HVM

[席康杰 <xikangjie@xxxxxx>]

Maybe not because of screen refresh issue, I create a Windows 10 HVM, when run command “sc start HyperPlatform”, the system also hangs but the screen is not broken.

 

And “xl dmesg” keep on outputing “(XEN) L0 PIO b001” :

 

…

(XEN) L0 PIO b001

(XEN) L0 PIO b001

(XEN) L0 PIO b001

(XEN) L0 PIO b001

(XEN) L0 PIO b001

(XEN) L0 PIO b001

(XEN) L0 PIO b001

(XEN) L0 PIO b001

(XEN) L0 PIO b001

(XEN) L0 PIO b001

(XEN) L0 PIO b001

…

 

Do you have any idea to debug this problem?

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:

 

   

 

However, when I install HyperPlatform (https://github.com/tandasat/HyperPlatform#installation-and-uninstallation) and finally run the command:

   

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
