Guest 3d graphics - security and memory usage

[kasper]

Guest 3d graphics uses additional physical memory.   Before allocation would be fixed.   Now 3d memory is dynamically allocated?

3d graphics has its own memory space.   Does this provide better security than not using it?

Thank you.

Yes, yes and yes.

Sandboxed Graphics Processes

• We’ve dramatically enhanced virtual machine security by using a special non-root “sandbox” process for rendering 3d hardware assisted graphics. This further isolates the Guest VM operations from the Host, significantly reducing the viability of privilege escalation to the host.
