qemu-guest-agent is:

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.
