2017-07-14char: chardevice hotswapAnton Nefedov
This patch adds a possibility to change a char device without a frontend removal. Ideally, it would have to happen transparently to a frontend, i.e. frontend would continue its regular operation. However, backends are not stateless and are set up by the frontends via qemu_chr_fe_<> functions, and it's not (generally) possible to replay that setup entirely in a backend code, as different chardevs respond to the setup calls differently, so do frontends work differently basing on those setup responses. Moreover, some frontend can generally get and save the backend pointer (qemu_chr_fe_get_driver()), and it will become invalid after backend change. So, a frontend which would like to support chardev hotswap has to register a "backend change" handler, and redo its backend setup there.

2017-06-29Add chardev-send-break monitor commandStefan Fritsch
Sending a break on a serial console can be useful for debugging the guest. But not all chardev backends support sending breaks (only telnet and mux do).

2017-06-28migration: add "return-path" capabilityPeter Xu
When this capability is enabled, QEMU will use the return path even for precopy migration. This is helpful at least in one case when destination failed to load the image while source quited without confirmation. With return path, source will wait for the last response from destination, and if destination fails, it'll fail the migration on source, then the guest can be run again on the source (rather than assuming to be good, then the guest will be lost after source quits). It needs to be enabled explicitly on source, otherwise disabled.

2017-05-11numa: add '-numa cpu,...' option for property based node mappingIgor Mammedov
legacy cpu to node mapping is using cpu index values to map VCPU to node with help of '-numa node,nodeid=node,cpus=x[-y]' option. However cpu index is internal concept and QEMU users have to guess /reimplement qemu's logic/ to map it to a concrete cpu socket/core/thread to make sane CPUs placement across numa nodes. This patch allows to map cpu objects to numa nodes using the same properties as used for cpus with -device/device_add (socket-id/core-id/thread-id/node-id). At present valid properties/values to address CPUs could be fetched using hotpluggable-cpus monitor/qmp command, it will require user to start qemu twice when creating domain to fetch possible CPUs for a machine type/-smp layout first and then the second time with numa explicit mapping for actual usage. The first step results could be saved and reused to set/change mapping later as far as machine type/-smp stays the same. Proposed impl. supports exact and wildcard matching to simplify CLI and allow to set mapping for a specific cpu or group of cpu objects specified by matched properties. For example: # exact mapping x86 -numa cpu,node-id=x,socket-id=y,core-id=z,thread-id=n # exact mapping SPAPR -numa cpu,node-id=x,core-id=y # wildcard mapping, all cpu objects that match socket-id=y # are mapped to node-id=x -numa cpu,node-id=x,socket-id=y Signed-off-by: Igor Mammedov <imammedo@redhat.com> Message-Id: <1494415802-227633-18-git-send-email-imammedo@redhat.com> Reviewed-by: David Gibson <david@gibson.dropbear.id.au> Signed-off-by: Eduardo Habkost <ehabkost@redhat.com>

2017-03-16migration: use "" as the default for tls-creds/hostnameDaniel P. Berrange
The tls-creds parameter has a default value of NULL indicating that TLS should not be used. Setting it to non-NULL enables use of TLS. Once tls-creds are set to a non-NULL value via the monitor, it isn't possible to set them back to NULL again, due to current implementation limitations. The empty string is not a valid QObject identifier, so this switches to use "" as the default, indicating that TLS will not be used The tls-hostname parameter has a default value of NULL indicating the the hostname from the migrate connection URI should be used. Again, once tls-hostname is set non-NULL, to override the default hostname for x509 cert validation, it isn't possible to reset it back to NULL via the monitor. The empty string is not a valid hostname, so this switches to use "" as the default, indicating that the migrate URI hostname should be used. Using "" as the default for both, also means that the monitor commands "info migrate_parameters" / "query-migrate-parameters" will report existance of tls-creds/tls-parameters even when set to their default values.

2017-03-16qapi: The #optional tag is redundant, dropMarkus Armbruster
We traditionally mark optional members #optional in the doc comment. Before commit 3313b61, this was entirely manual. Commit 3313b61 added some automation because its qapi2texi.py relied on #optional to determine whether a member is optional. This is no longer the case since the previous commit: the only thing qapi2texi.py still does with #optional is stripping it out. We still reject bogus qapi-schema.json and six places for qga/qapi-schema.json. Thus, you can't actually rely on #optional to see whether something is optional. Yet we still make people add it manually. That's just busy-work. Drop the code to check, fix up and strip out #optional, along with all instances of #optional. To keep it out, add code to reject it, to be dropped again once the dust settles. No change to generated documentation.

For the above, we get in qemu-qmp-qapi.texi @item @code{'name'} (optional) The name of the guest @end table The extra space can lead to artifacts in output, e.g in qemu-qmp-ref.7.pod =item C<'name'> (optional) The name of the guest and then in qemu-qmp-ref.7 .IX Item "name (optional)" .Vb 1 \& The name of the guest .Ve instead of intended plain .IX Item "name (optional)" The name of the guest Get rid of these artifacts by removing whitespace around #optional along with it.

2017-02-27qapi-schema: Comment about full expansion of non-migration-safe modelsEduardo Habkost
Add a note warning that static expansion may not be 100% accurate when the CPU model is not migration-safe. This will be the case on x86 when expansing the "host" CPU model, because there are "host" features that can't have a migration-safe representation (e.g. "host-cache-info").

2017-02-22net: Flatten simple union NetLegacyOptionsMarkus Armbruster
Simple unions are simpler than flat unions in the schema, but more complicated in C and on the QMP wire: there's extra indirection in C and extra nesting on the wire, both pointless. They're best avoided in new code. NetLegacyOptions isn't new, but it's only used internally, not in QMP. Convert it to a flat union.

We should not do failover work while the main thread is loading VM's state. Otherwise the consistent of VM's memory and device state will be broken.

This feature frees the migrated memory on the source during postcopy-ram migration. In the second step of postcopy-ram migration when the source vm is put on pause we can free unnecessary memory. It will allow, in particular, to start relaxing the memory stress on the source host in a load-balancing scenario.

2017-02-08ui: fix reporting of VNC auth in query-vnc-serversDaniel P. Berrange
Currently the VNC authentication info is emitted at the top level of the query-vnc-servers data. This is wrong because the authentication scheme differs between plain and websockets when TLS is enabled. We should instead report auth against the individual servers. e.g. (QEMU) query-vnc-servers { "return": [ { "clients": [], "id": "default", "auth": "vencrypt", "vencrypt": "x509-vnc", "server": [ { "host": "127.0.0.1" "service": "5901", "websocket": false, "family": "ipv4", "auth": "vencrypt", "vencrypt": "x509-vnc" }, { "host": "127.0.0.1", "service": "5902", "websocket": true, "family": "ipv4", "auth": "vnc" } ] } ] } This also future proofs the QMP schema so that we can cope with multiple VNC server instances, listening on different interfaces or ports, with different auth setup.
