I/O virtualization needs to resolve the following two problems:

Select one or more of the following:

  • Reuse the memory: Many VM request great amount the memory

  • Device discovery: Controls the devices accessible to VMs.

  • Access interception: Processes devices' access requests through I/O ports.

  • Try and try CPU resources: Many VM request great amount the CPU instructions

Explanation

Question 100 of 114

1

In the I/O virtualization, How to discover a device? (Three answers)

Select one or more of the following:

  • The device information about all VMs is saved on the XenStore of Domain0.

  • The XenBus (a paravirtualizaton driver designed for Xen) on VMs communicates with the XenStore of Domain0 to obtain device information.

  • The front-end driver for the device is loaded.

  • The front-end OS for the device is loaded.

Explanation

Question 101 of 114

1

In I/O virtualization, How to intercept device data? (two answers)

Select one or more of the following:

  • The front-end device driver forwards data completely to the back-end driver through the interfaces provided by the VMM.

  • The back-end driver processes VM data on a time and channel basis.

  • The front-end device driver forwards I/O instructions to core cpu

  • The back-end driver processes data host
