[PATCH v3 00/15] Introduce virtio-mem <memory/> model
v3 of:
https://listman.redhat.com/archives/libvir-list/2021-February/msg00961.html
diff to v2:
- Dropped code that forbade use of virtio-mem and memballoon at the same
time;
- This meant that I had to adjust memory accounting,
qemuDomainSetMemoryFlags() - see patches 11/15 and 12/15 which are new.
- Fixed small nits raised by Peter in his review of v2
Michal Prívozník (15):
virhostmem: Introduce virHostMemGetTHPSize()
qemu_process: Deduplicate code in qemuProcessNeedHugepagesPath()
qemu_process: Drop needless check in
qemuProcessNeedMemoryBackingPath()
qemu_capabilities: Introduce QEMU_CAPS_DEVICE_VIRTIO_MEM_PCI
conf: Introduce virtio-mem <memory/> model
qemu: Build command line for virtio-mem
qemu: Wire up <memory/> live update
qemu: Wire up MEMORY_DEVICE_SIZE_CHANGE event
Introduce MEMORY_DEVICE_SIZE_CHANGE event
qemu: Refresh the actual size of virtio-mem on monitor reconnect
qemu: Account for both memballoon and virtio-mem
qemuDomainSetMemoryFlags: Take virtio-mem into consideration
virsh: Introduce update-memory-device command
