qemu: fast processor emulator, dummy package

 QEMU is a fast processor emulator. Once upon a time there was only one
 package named `qemu', with all functionality included. These days, qemu
 become large and has been split into numerous packages. Different packages
 provides entirely different services, and it is very unlikely one will
 need all of them together. So current `qemu' package makes no sense anymore,
 and is becoming a dummy package.
 .
 If you want full system emulation of some architecture, install one or more
 of qemu-system-ARCH packages. If you want user-mode emulation, install
 qemu-user or qemu-user-static package. If you need utilities, use qemu-utils
 package.
 .
 This package can safely be removed.

qemu-block-extra: extra block backend modules for qemu-system and qemu-utils

 QEMU is a fast processor emulator: currently the package supports
 ARM, CRIS, i386, M68k (ColdFire), MicroBlaze, MIPS, PowerPC, SH4,
 SPARC and x86-64 emulation. By using dynamic translation it achieves
 reasonable speed while being easy to port on new host CPUs.
 .
 This package provides extra block device backend modules for qemu-system
 emulation and qemu-img from qemu-utils package, which are rarely used and
 has extra dependencies.

qemu-guest-agent: Guest-side qemu-system agent

 QEMU is a fast processor emulator: currently the package supports
 ARM, CRIS, i386, M68k (ColdFire), MicroBlaze, MIPS, PowerPC, SH4,
 SPARC and x86-64 emulation. By using dynamic translation it achieves
 reasonable speed while being easy to port on new host CPUs.
 .
 This package provides a daemon (agent) to run inside qemu-system
 guests (full system emulation). It communicates with the host using
 a virtio-serial channel org.qemu.guest_agent.0, and allows one to 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.
 .
 Install this package on a system which is running as guest inside
 qemu virtual machine. It is not used on the host.
