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 . v4->v5: - rebase on top of last Michael S. Tsirkin PULL request - block live migration if !PROTOCOL_F_LOG_SHMFD - wait for a reply after SET_LOG_BASE - split vhost_set_log_base from the rest of vhost_call refactoring - use a seperate global vhost_log_shm 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 (18): configure: probe for memfd util: add linux-only memfd fallback util: add memfd helpers vhost: alloc shareable log vhost: document log resizing vhost: add vhost_set_log_base op vhost-user: send log shm fd along with log_base vhost-user: add a migration blocker vhost: use a function for each call 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.
