Summary
In this chapter, we covered virtual display devices and protocols used to display virtual machine data. We also did some digging into the world of GPU sharing and GPU passthrough, which are important concepts for large-scale virtualized environments running VDI. We discussed some benefits and drawbacks to these scenarios as they tend to be rather complex to implement and require a lot of resources – financial resources included. Imagine having to do PCI passthrough for 2D/3D acceleration for 100 virtual machines. That would actually require buying 100 graphic cards, which is a big, big ask financially. Among the other topics we discussed, we went through various display protocols and options that can be used for console access to our virtual machines.
In the next chapter, we will take you through some regular virtual machine operations – installation, configuration, and life cycle management, including discussing snapshots and virtual machine migration.
