David Hildenbrand b430b51395 util/vfio-helpers.c: Use ram_block_discard_disable() in qemu_vfio_open_pci() ... Currently, when using "nvme://" for a block device, like -drive file=nvme://0000:01:00.0/1,if=none,id=drive0 \ -device virtio-blk,drive=drive0 \ VFIO may pin all guest memory, and discarding of RAM no longer works as expected. I was able to reproduce this easily with my 01:00.0 Non-Volatile memory controller: Samsung Electronics Co Ltd NVMe SSD Controller SM981/PM981/PM983 Similar to common VFIO, we have to disable it, making sure that: a) virtio-balloon won't discard any memory ("silently disabled") b) virtio-mem and nvme:// run mutually exclusive Cc: Paolo Bonzini <pbonzini@redhat.com> Cc: "Michael S.
