2020-06-17hmp: Make json format optional for qom-setDavid Hildenbrand
Commit 7d2ef6dcc1cf ("hmp: Simplify qom-set") switched to the json parser, making it possible to specify complex types. However, with this change it is no longer possible to specify proper sizes (e.g., 2G, 128M), turning the interface harder to use for properties that consume sizes. Let's switch back to the previous handling and allow to specify passing json via the "-j" parameter.

2019-02-25block/snapshot.c: eliminate use of ID input in snapshot operationsDaniel Henrique Barboza
At this moment, QEMU attempts to create/load/delete snapshots by using either an ID (id_str) or a name. The problem is that the code isn't consistent of whether the entered argument is an ID or a name, causing unexpected behaviors. For example, when creating snapshots via savevm <arg>, what happens is that "arg" is treated as both name and id_str. In a guest without snapshots, create a single snapshot via savevm: (qemu) savevm 0 (qemu) info snapshots List of snapshots present on all disks: ID TAG VM SIZE DATE VM CLOCK -- 0 741M 2018-07-31 13:39:56 00:41:25.313 A snapshot with name "0" is created. ID is hidden from the user, but the ID is a non-zero integer that starts at "1". Thus, this snapshot has id_str=1, TAG="0". Creating a second snapshot with arg = 1, the first one is deleted: (qemu) savevm 1 (qemu) info snapshots List of snapshots present on all disks: ID TAG VM SIZE DATE VM CLOCK -- 1 741M 2018-07-31 13:42:14 00:41:55.252 What happened? - when creating the second snapshot, a verification is done inside bdrv_all_delete_snapshot to delete any existing snapshots that matches an string argument. Here, the code calls bdrv_all_delete_snapshot("1", ...); - bdrv_all_delete_snapshot calls bdrv_snapshot_find(..., "1") for each BlockDriverState of the guest. And this is where things goes tilting: bdrv_snapshot_find does a search by both id_str and name. It finds out that there is a snapshot that has id_str = 1, stores a reference to the snapshot in the sn_info pointer and then returns match found; - since a match was found, a call to bdrv_snapshot_delete_by_id_or_name() is made. This function ignores the pointer written by bdrv_snapshot_find. Instead, it deletes the snapshot using bdrv_snapshot_delete() calling it first with id_str = 1. If it fails to delete, then it calls it again with name = 1. - after all that, QEMU creates the new snapshot, that has id_str = 1 and name = 1. The user is left wondering that happened with the first snapshot created. Similar bugs can be triggered when using loadvm and delvm. Before contemplating discarding the use of ID input in these operations, I've searched the code of what would be the implications. My findings are: - the RBD and Sheepdog drivers don't care. Both uses the 'name' field as key in their logic, making id_str = name when appropriate. replay-snapshot.c does not make any special use of id_str; - qcow2 uses id_str as an unique identifier but it is automatically calculated, not being influenced by user input. Other than that, there are no distinguish operations made only with id_str; - in blockdev.c, the delete operation uses a match of both id_str AND name. Given that id_str is either a copy of 'name' or auto-generated, we're fine here. This gives motivation to not consider ID as a valid user input in HMP commands - sticking with 'name' input only is more consistent. To accomplish that, the following changes were made in this patch: - bdrv_snapshot_find() does not match for id_str anymore, only 'name'. The function is called in save_snapshot(), load_snapshot(), bdrv_all_delete_snapshot() and bdrv_all_find_snapshot(). This change makes the search function more predictable and does not change the behavior of any underlying code that uses these affected functions, which are related to HMP (which is fine) and the main loop inside vl.c (which doesn't care about it anyways); - bdrv_all_delete_snapshot() does not call bdrv_snapshot_delete_by_id_or_name anymore. Instead, it uses the pointer returned by bdrv_snapshot_find to erase the snapshot with the exact match of id_str an name. This function is called in save_snapshot and hmp_delvm, thus this change produces the intended effect; - documentation changes to reflect the new behavior. I consider this to be an API fix instead of an API change - the user was already creating snapshots using 'name', but now he/she will also enjoy a consistent behavior. Ideally we would get rid of the id_str field entirely, but this would have repercussions on existing snapshots. Another day perhaps.

2018-03-19block/mirror: change the semantic of 'force' of block-job-cancelLiang Li
When doing drive mirror to a low speed shared storage, if there was heavy BLK IO write workload in VM after the 'ready' event, drive mirror block job can't be canceled immediately, it would keep running until the heavy BLK IO workload stopped in the VM. Libvirt depends on the current block-job-cancel semantics, which is that when used without a flag after the 'ready' event, the command blocks until data is in sync. However, these semantics are awkward in other situations, for example, people may use drive mirror for realtime backups while still wanting to use block live migration. Libvirt cannot start a block live migration while another drive mirror is in progress, but the user would rather abandon the backup attempt as broken and proceed with the live migration than be stuck waiting for the current drive mirror backup to finish. The drive-mirror command already includes a 'force' flag, which libvirt does not use, although it documented the flag as only being useful to quit a job which is paused. However, since quitting a paused job has the same effect as abandoning a backup in a non-paused job (namely, the destination file is not in sync, and the command completes immediately), we can just improve the documentation to make the force flag obviously useful.

2018-01-29net: Allow netdevs to be used with 'hostfwd_add' and 'hostfwd_remove'Thomas Huth
It does not make much sense to limit these commands to the legacy 'vlan' concept only, they should work with the modern netdevs, too. So now it is possible to use this command with one, two or three parameters. With one parameter, the command installs a hostfwd rule on the default "user" network: hostfwd_add tcp:... With two parameters, the command installs a hostfwd rule on a netdev (that's the new way of using this command): hostfwd_add netdev_id tcp:... With three parameters, the command installs a rule on a 'vlan' (aka hub): hostfwd_add hub_id name tcp:... Same applies to the hostfwd_remove command now.

2018-01-26hmp: Add nbd_server_remove to mirror QMP commandEric Blake
Since everything else about the nbd-server-* QMP commands is accessible from HMP, we might as well make removing an export available as well. For now, I went with a bool flag rather than a mode string for choosing between safe (default) and hard modes.

It's easy to use device_add and device_del as replacement instead. The usb_add and usb_del commands are deprecated since QEMU 2.10, and nobody complained that they are still needed, so let's get rid of them now to make the HMP interface a little bit less overloaded.

2017-07-11block: remove all encryption handling APIsDaniel P. Berrange
Now that all encryption keys must be provided upfront via the QCryptoSecret API and associated block driver properties there is no need for any explicit encryption handling APIs in the block layer. Encryption can be handled transparently within the block driver. We only retain an API for querying whether an image is encrypted or not, since that is a potentially useful piece of metadata to report to the user.

2016-10-30COLO: Add 'x-colo-lost-heartbeat' command to trigger failoverzhanghailiang
We leave users to choose whatever heartbeat solution they want, if the heartbeat is lost, or other errors they detect, they can use experimental command 'x_colo_lost_heartbeat' to tell COLO to do failover, COLO will do operations accordingly. For example, if the command is sent to the Primary side, the Primary side will exit COLO mode, does cleanup work, and then, PVM will take over the service work. If sent to the Secondary side, the Secondary side will run failover work, then takes over PVM's service work.

2016-09-05drive-backup: added support for data compressionPavel Butsykin
The idea is simple - backup is "written-once" data. It is written block by block and it is large enough. It would be nice to save storage space and compress it. The patch adds a flag to the qmp/hmp drive-backup command which enables block compression. Compression should be implemented in the format driver to enable this feature. There are some limitations of the format driver to allow compressed writes. We can write data only once. Though for backup this is perfectly fine. These limitations are maintained by the driver and the error will be reported if we are doing something wrong.
