2020-06-26numa: forbid '-numa node, mem' for 5.1 and newer machine typesIgor Mammedov1-17/+20
Deprecation period is run out and it's a time to flip the switch introduced by cd5ff8333a. Disable legacy option for new machine types (since 5.1) and amend documentation. '-numa node,memdev' shall be used instead of disabled option with new machine types.

2020-06-12Lift max memory slots limit imposed by vhost-userRaphael Norwitz1-4/+3
Historically, sending all memory regions to vhost-user backends in a single message imposed a limitation on the number of times memory could be hot-added to a VM with a vhost-user device. Now that backends which support the VHOST_USER_PROTOCOL_F_CONFIGURE_SLOTS send memory regions individually, we no longer need to impose this limitation on devices which support this feature. With this change, VMs with a vhost-user device which supports the VHOST_USER_PROTOCOL_F_CONFIGURE_MEM_SLOTS can support a configurable number of memory slots, up to the maximum allowed by the target platform. Existing backends which do not support VHOST_USER_PROTOCOL_F_CONFIGURE_MEM_SLOTS are unaffected.

2020-06-12Transmit vhost-user memory regions individuallyRaphael Norwitz1-2/+31
With this change, when the VHOST_USER_PROTOCOL_F_CONFIGURE_MEM_SLOTS protocol feature has been negotiated, Qemu no longer sends the backend all the memory regions in a single message. Rather, when the memory tables are set or updated, a series of VHOST_USER_ADD_MEM_REG and VHOST_USER_REM_MEM_REG messages are sent to transmit the regions to map and/or unmap instead of sending send all the regions in one fixed size VHOST_USER_SET_MEM_TABLE message. The vhost_user struct maintains a shadow state of the VM’s memory regions. When the memory tables are modified, the vhost_user_set_mem_table() function compares the new device memory state to the shadow state and only sends regions which need to be unmapped or mapped in. The regions which must be unmapped are sent first, followed by the new regions to be mapped in. After all the messages have been sent, the shadow state is set to the current virtual device state. Existing backends which do not support VHOST_USER_PROTOCOL_F_CONFIGURE_MEM_SLOTS are unaffected.

This change introduces a new feature to the vhost-user protocol allowing a backend device to specify the maximum number of ram slots it supports. At this point, the value returned by the backend will be capped at the maximum number of ram slots which can be supported by vhost-user, which is currently set to 8 because of underlying protocol limitations. The returned value will be stored inside the VhostUserState struct so that on device reconnect we can verify that the ram slot limitation has not decreased since the last time the device connected.

2020-05-28qemu-img: Add convert --bitmaps optionEric Blake1-1/+5
Make it easier to copy all the persistent bitmaps of (the top layer of) a source image along with its guest-visible contents, by adding a boolean flag for use with qemu-img convert. This is basically shorthand, as the same effect could be accomplished with a series of 'qemu-img bitmap --add' and 'qemu-img bitmap --merge -b source' commands, or by their corresponding QMP commands. Note that this command will fail in the same scenarios where 'qemu-img measure' omits a 'bitmaps size:' line, namely, when either the source or the destination lacks persistent bitmap support altogether. See also https://bugzilla.redhat.com/show_bug.cgi?id=1779893 While touching this, clean up a couple coding issues spotted in the same function: an extra blank line, and merging back-to-back 'if (!skip_create)' blocks.

2020-05-28qcow2: Expose bitmaps' size during measureEric Blake1-0/+7
It's useful to know how much space can be occupied by qcow2 persistent bitmaps, even though such metadata is unrelated to the guest-visible data. Report this value as an additional QMP field, present when measuring an existing image and output format that both support bitmaps. Update iotest 178 and 190 to updated output, as well as new coverage in 190 demonstrating non-zero values made possible with the recently-added qemu-img bitmap command (see 3b51ab4b). The new 'bitmaps size:' field is displayed automatically as part of 'qemu-img measure' any time it is present in QMP (that is, any time both the source image being measured and destination format support bitmaps, even if the measurement is 0 because there are no bitmaps present). If the field is absent, it means that no bitmaps can be copied (source, destination, or both lack bitmaps, including when measuring based on size rather than on a source image). This behavior is compatible with an upcoming patch adding 'qemu-img convert --bitmaps': that command will fail in the same situations where this patch omits the field. The addition of a new field demonstrates why we should always zero-initialize qapi C structs; while the qcow2 driver still fully populates all fields, the raw and crypto drivers had to be tweaked to avoid uninitialized data. Consideration was also given towards having a 'qemu-img measure --bitmaps' which errors out when bitmaps are not possible, and otherwise sums the bitmaps into the existing allocation totals rather than displaying as a separate field, as a potential convenience factor. But this was ultimately decided to be more complexity than necessary when the QMP interface was sufficient enough with bitmaps remaining a separate field.

2020-05-19qemu-img: Add bitmap sub-commandEric Blake1-0/+24
Include actions for --add, --remove, --clear, --enable, --disable, and --merge (note that --clear is a bit of fluff, because the same can be accomplished by removing a bitmap and then adding a new one in its place, but it matches what QMP commands exist). Listing is omitted, because it does not require a bitmap name and because it was already possible with 'qemu-img info'. A single command line can play one or more bitmap commands in sequence on the same bitmap name (although all added bitmaps share the same granularity, and and all merged bitmaps come from the same source file). Merge defaults to other bitmaps in the primary image, but can also be told to merge bitmaps from a distinct image. While this supports --image-opts for the file being modified, I did not think it worth the extra complexity to support that for the source file in a cross-file merges. Likewise, I chose to have --merge only take a single source rather than following the QMP support for multiple merges in one go (although you can still use more than one --merge in the command line); in part because qemu-img is offline and therefore atomicity is not an issue. Upcoming patches will add iotest coverage of these commands while also testing other features.
