baloon driver: free-page-reporting support #899

Open JuniorJPDJ opened 1 year ago

JuniorJPDJ commented 1 year ago

Linux kernel driver supports it since 5.7 release (https://git.kernel.org/pub/scm/linux/kernel/git/torvalds/linux.git/commit/?id=b0c504f154718904ae49349147e3b7e6ae91ffdc). It allows QEMU to free unused guest memory on host side and allows overcommiting memory.

any plan？

YanVugenfirer commented 3 months ago

A low-priority issue for us for now. It is not planned until Windows Server 2025 is released.

qemu have hv-balloon now, it seems better than virtio-balloon, still we need virtio-balloon, any suggestion?

YanVugenfirer commented 3 months ago

It depends on your setup. You can choose to use hv-baloon or virtio-mem.
