It's useful, but is not strictly needed. Qemu-kvm can emulate IDE drives (slow), SATA drives (faster), SCSI drives (even faster, but its BIOS is unable to boot from such) and so called Virtio drives (fastest, basically custom PCI devices). Depending on the guest OS - you may need custom drivers for Virtio. It's the same with the network - there are slow ones (venerable ne2k, AMD lance), faster ones (Realtek r8139, Intel e1000), and custom PCI Virtio ones. And there's so called qemu-guest-agent, which, according to the description, should 'perform some functions in the guest from the host, including': - querying and setting guest system time - performing guest filesystem sync operation - initiating guest shutdown or suspend to ram - accessing guest files - freezing/thawing guest filesystem operations - others.
