Packages
qemu-guest-agent(RPM) -- QEMU guest agent daemon
Usage
# image.yml -- typically used via bootc-base composition
my-vm-image:
bootc: true
layers:
- bootc-base
Used In Images
Part of the bootc-base composition layer. Used transitively in bootc/VM images.
virtio-serial channel (libvirt XML contribution)
The layer contributes a raw libvirt XML snippet that the libvirt renderer places in the VM's <devices> section:
<channel type='unix'>
<target type='virtio' name='org.qemu.guest_agent.0'/>
</channel>
Emitted in layer.yml as:
libvirt:
snippets:
- "<channel type='unix'><target type='virtio' name='org.qemu.guest_agent.0'/></channel>"
This is the / classification case: isDeviceElement flags it as device-scoped, so the renderer injects it inside <devices> rather than before </domain>. See /ov-dev:libvirt-renderer for the injection pipeline and /ov:vm for the QEMU-user-net caveat (the agent shows as enabled/inactive under ov's QEMU backend; libvirt backend activates it).
