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>

In the unfortunate event that bugs are discovered, they should be reported to the appropriate bug tracker. If you obtained the software from a 3rd party operating system vendor, it is often wise to use their own bug tracker for reporting problems. In all other cases use the master OpenStack bug tracker, available at:
