For virtualization options, you will be able to :
Virtualize Intel VT-x/EPT or AMD-V/RVI :
virtualize the Intel VT-x/EPT or AMD-V/RVI virtualization instructions of the host PC processor so that they can also be available in the virtual machine.This will only be necessary in rare cases : when you want to install VirtualBox in a VMware virtual machine, virtualize a virtualization server (as VMware ESXi or Citrix XenServer), ...
虚拟化 Intel VT-x/EPT 或 AMD-V/RVI :
虚拟化主机 PC 处理器的 Intel VT-x/EPT 或 AMD-V/RVI 虚拟化指令,以便它们也可以在虚拟机中使用。这仅在极少数情况下才有必要:当您想在 VMware 虚拟机中安装 VirtualBox 时,虚拟化虚拟化服务器(如 VMware ESXi 或 Citrix XenServer),...
Virtualize CPU performance counters :
virtualize CPU performance counters to monitor CPU usage with applications running in the virtual machine, using OProfile (on Linux) or VTune (on Windows).
虚拟化 CPU 性能计数器:
使用 OProfile(在 Linux 上)或 VTune(在 Windows 上),虚拟化 CPU 性能计数器以监视在虚拟机中运行的应用程序的 CPU 使用率。
Virtualize IOMMU (IO memory management unit) :
allows you to virtualize the IOMMU (of AMD) or Intel VT-d and thus block the direct access to the memory from the virtual machine.This feature is required by the Citrix XenServer virtualization server when you want to test PCI passthrough with a Citrix VM on Windows.
Virtualize IOMMU(IO 内存管理单元):
允许您虚拟化 IOMMU(来自 AMD)或 Intel VT-d,从而阻止从虚拟机直接访问内存。当您要在 Windows 上使用 Citrix VM 测试 PCI 直通时,Citrix XenServer 虚拟化服务器需要此功能。
