qemu-guest-agent 1:4.2-3ubuntu6 (amd64 binary) in ubuntu focal

 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.
