On qemu-side, the solution is fairly straightfoward since vhost already supports the dirty log, only vhost-user couldn't access the log memory until then. The series includes "protocol feature negotiation" series proposed earlier by Michael S. Tsirkinm and "vhost user: Add live migration" series from Thibaut Collet . v3->v4: - add the proto negotiation & the migration series - replace the varargs vhost_call() approach for callbacks - only share-allocate when the backend needs it v2->v3: - changed some patch summary - added migration tests - added a patch to replace error message with a trace The development branch I used is: https://github.com/elmarco/qemu branch "vhost-user" Marc-André Lureau (17): configure: probe for memfd util: add linux-only memfd fallback util: add memfd helpers vhost: alloc shareable log vhost: document log resizing vhost: use a function for each call vhost-user: remove vhost_user_request_translate() vhost-user: send log shm fd along with log_base vhost: only use shared log if in use by backend vhost-user: document migration log net: add trace_vhost_user_event vhost-user-test: move wait_for_fds() out vhost-user-test: remove useless static check vhost-user-test: wrap server in TestServer struct vhost-user-test: learn to tweak various qemu arguments vhost-user-test: add live-migration test vhost-user-test: check ownership during migration Michael S. Tsirkin (3): vhost-user: refactor ioctl translation vhost-user: add protocol feature negotiation vhost-user: unit test for new messages Thibaut Collet (2): vhost user: add support of live migration vhost user: add rarp sending after live migration for legacy guest configure | 19 ++ docs/specs/vhost-user.txt | 94 +++++++ hw/net/vhost_net.c | 33 ++- hw/scsi/vhost-scsi.c | 7 +- hw/virtio/vhost-backend.c | 142 +++++++++- hw/virtio/vhost-user.c | 533 +++++++++++++++++++++++++++----------- hw/virtio/vhost.c | 82 ++++-- include/hw/virtio/vhost-backend.h | 68 ++++- include/hw/virtio/vhost.h | 4 +- include/net/vhost_net.h | 1 + include/qemu/memfd.h | 24 ++ net/vhost-user.c | 37 ++- tests/vhost-user-test.c | 381 ++++++++++++++++++++++----- trace-events | 4 + util/Makefile.objs | 2 +- util/memfd.c | 126 +++++++++ 16 files changed, 1283 insertions(+), 274 deletions(-) create mode 100644 include/qemu/memfd.h create mode 100644 util/memfd.c -- 2.4.3
