The libvirt driver now automatically enables autodeflate and freePageReporting attributes for virtio memory balloon devices. The autodeflate feature allows the QEMU virtio memory balloon to release memory before the Out of Memory killer activates. The freePageReporting feature enables returning unused pages back to the hypervisor for use by other guests or processes, improving overall memory efficiency on compute hosts. These features are always enabled when a memballoon device is configured, requiring no additional configuration from operators. implements: blueprint automatic-memballoon-freeing Generated-By: claude-code Change-Id: If47a6d38cd311b08b78acffb307a99a7a2a080a1 Signed-off-by: Sean Mooney <work@seanmooney.info>

The libvirt driver now automatically enables ``autodeflate`` and
|
|
``freePageReporting`` features for virtio memory balloon devices.
|
|
The ``autodeflate`` feature allows the QEMU virtio memory balloon
|
|
to release memory at the last moment before a guest process is
|
|
killed by the Out of Memory killer. The ``freePageReporting``
|
|
feature enables the memory balloon to return unused pages back
|
|
to the hypervisor for use by other guests or processes, improving
|
|
overall memory efficiency on the compute host.
