modified guest OSes are allowed to run. This way, most of the hardware access is abstracted and any functions which would normally access the hardware or privileged CPU state are passed on to the hypervisor asynchronous I/O. This does not apply to VDI files and raw disk/partition VMDK files, which do support async I/O. This restriction will be lifted in a future maintenance update. 208 13 Known limitations • “library” means a collection of software functions and/or data prepared so as to be conveniently linked with application programs (which use some of those functions and data) to form executables.
