Back in March in ed627b2ad37469eeba9e Maxime has a dpdk set to be merged, but we're just working a bug at the moment that we've not figured out yet (could be either side).

[Qemu-devel] [PATCH v4 00/29] postcopy+vhost-user/shared ram
From: "Dr. David Alan Gilbert"This set enables postcopy migration with shared memory to a vhost user process. It's based off current head. Testing is mostly performed with dpdk, with corresponding modifications by Maxime. v4 is mostly just fixes from comments received during review of v3, and the normal updating of all the virtio enum's to catch up with other things getting in before us. Dave Dr. David Alan Gilbert (29): migrate: Update ram_block_discard_range for shared qemu_ram_block_host_offset postcopy: use UFFDIO_ZEROPAGE only when available postcopy: Add notifier chain postcopy: Add vhost-user flag for postcopy and check it vhost-user: Add 'VHOST_USER_POSTCOPY_ADVISE' message libvhost-user: Support sending fds back to qemu libvhost-user: Open userfaultfd postcopy: Allow registering of fd handler vhost+postcopy: Register shared ufd with postcopy vhost+postcopy: Transmit 'listen' to client postcopy+vhost-user: Split set_mem_table for postcopy migration/ram: ramblock_recv_bitmap_test_byte_offset libvhost-user+postcopy: Register new regions with the ufd vhost+postcopy: Send address back to qemu vhost+postcopy: Stash RAMBlock and offset vhost+postcopy: Send requests to source for shared pages vhost+postcopy: Resolve client address postcopy: helper for waking shared postcopy: postcopy_notify_shared_wake vhost+postcopy: Add vhost waker vhost+postcopy: Call wakeups libvhost-user: mprotect & madvises for postcopy vhost-user: Add VHOST_USER_POSTCOPY_END message vhost+postcopy: Wire up POSTCOPY_END notify vhost: Huge page align and merge postcopy: Allow shared memory libvhost-user: Claim support for postcopy postcopy shared docs contrib/libvhost-user/libvhost-user.c | 303 - contrib/libvhost-user/libvhost-user.h | 11 + docs/devel/migration.rst | 41 docs/interop/vhost-user.txt | 51 + exec.c| 86 +-- hw/virtio/trace-events| 16 +- hw/virtio/vhost-user.c| 411 +- hw/virtio/vhost.c | 66 +- include/exec/cpu-common.h | 4 + migration/migration.c | 6 + migration/migration.h | 4 + migration/postcopy-ram.c | 354 +++-- migration/postcopy-ram.h | 69 ++ migration/ram.c | 5 + migration/ram.h | 1 + migration/savevm.c| 13 ++ migration/trace-events| 6 + trace-events | 3 +- vl.c | 2 + 19 files changed, 1354 insertions(+), 98 deletions(-) -- 2.14.3
