### The required feature described as a wish Current versions of libvirt support additional memory ballooning options of Free Page Reporting and autodeflate which in theory can help VMs effectively share physical memory. At least with KVM, its not clear why memory overprovisioning toggles exist since this feature isn't enabled in the libvirt xml so no automatic ballooning will occur. Openstack's nova recently made this same change: https://github.com/openstack/nova/commit/cd401c5c1b5dcba739d69875795828e1be1d726b This feature was introduced all the way back in libvirt v6.9.0 (2020-11-02), so its not exactly a new feature. While this may not be of a benefit to true production workloads, we have a use-case where developers are spinning up environments to run large, but infrequent builds with VMs set to 256G+ memory, but they consume less than 1G most of the time. It would be great to be able to better utilize the hardware resources for this usecase. -- This is an automated message from the Apache Git Service.
