* spec: add qcow2 bitmaps extension specificationVladimir Sementsov-Ogievskiy2016-02-221-1/+220
| | | | | | | | | | | | | | | | | | | The new feature for qcow2: storing bitmaps. This patch adds new header extension to qcow2 - Bitmaps Extension. It provides an ability to store virtual disk related bitmaps in a qcow2 image. For now there is only one type of such bitmaps: Dirty Tracking Bitmap, which just tracks virtual disk changes from some moment. Note: Only bitmaps, relative to the virtual disk, stored in qcow2 file, should be stored in this qcow2 file. The size of each bitmap (considering its granularity) is equal to virtual disk size.

* vhost-user: clarify start and enableMichael S. Tsirkin2015-11-251-5/+15
| | | | | | | | | | | | | | | | It seems that we currently have some duplication between started and enabled states. The actual reason is that enable is not documented correctly: what it does is connecting ring to the backend. This is important for MQ, because a Linux guest expects TX packets to be completed even if it disables some queues temporarily.

| * vhost user: add rarp sending after live migration for legacy guestThibaut Collet2015-10-221-0/+15
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | A new vhost user message is added to allow QEMU to ask to vhost user backend to broadcast a fake RARP after live migration for guest without GUEST_ANNOUNCE capability. This new message is sent only if the backend supports the new VHOST_USER_PROTOCOL_F_RARP protocol feature. The payload of this new message is the MAC address of the guest (not known by the backend). The MAC address is copied in the first 6 bytes of a u64 to avoid to create a new payload message type. This new message has no equivalent ioctl so a new callback is added in the userOps structure to send the request. Upon reception of this new message the vhost user backend must generate and broadcast a fake RARP request to notify the migration is terminated.

* vhost-user: add multiple queue supportChangchun Ouyang2015-09-241-0/+15
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | This patch is initially based a patch from Nikolay Nikolaev. This patch adds vhost-user multiple queue support, by creating a nc and vhost_net pair for each queue. Qemu exits if find that the backend can't support the number of requested queues (by providing queues=# option). The max number is queried by a new message, VHOST_USER_GET_QUEUE_NUM, and is sent only when protocol feature VHOST_USER_PROTOCOL_F_MQ is present first. The max queue check is done at vhost-user initiation stage. We initiate one queue first, which, in the meantime, also gets the max_queues the backend supports. In older version, it was reported that some messages are sent more times than necessary. Here we came an agreement with Michael that we could categorize vhost user messages to 2 types: non-vring specific messages, which should be sent only once, and vring specific messages, which should be sent per queue. Here I introduced a helper function vhost_user_one_time_request(), which lists following messages as non-vring specific messages: VHOST_USER_SET_OWNER VHOST_USER_RESET_DEVICE VHOST_USER_SET_MEM_TABLE VHOST_USER_GET_QUEUE_NUM For above messages, we simply ignore them when they are not sent the first time.

But after this patch, only memory@0 node for RMA is built upfront. Guest kernel boots with just that and rest of the memory nodes (via memory@XXX or ibm,dynamic-reconfiguration-memory) are built when guest does ibm,client-architecture-support call.

* vhost-user: add multi queue supportOuyang Changchun2015-06-011-0/+5
| | | | | | | | | | | | | Based on patch by Nikolay Nikolaev: Vhost-user will implement the multi queue support in a similar way to what vhost already has - a separate thread for each queue. To enable the multi queue functionality - a new command line parameter "queues" is introduced for the vhost-user netdev.

| | | | | | | | | | | | Specify the upper limit of refcount_order to be 6 (that is, refcount_bits = 64). Any larger value does not make much sense when all offsets, sizes, cluster counts etc. "only" have a width of 64 bit as well, and very large values would be very difficult to support. Therefore, just cap it at the largest reasonable value. Suggested-by: Eric Blake <eblake@redhat.com> Signed-off-by: Max Reitz <mreitz@redhat.com> Signed-off-by: Kevin Wolf <kwolf@redhat.com>
