2018-01-15migration: put the finish part into a new functionPeter Xu
This patch only moved the last part of migration_thread() into a new function migration_iteration_finish() to make it much shorter.

2018-01-15migration: move vm_old_running into global statePeter Xu
Firstly, it was passed around. Let's just move it into MigrationState just like many other variables as state of migration, renaming it to vm_was_running. One thing to mention is that for postcopy, we actually don't need this knowledge at all since postcopy can't resume a VM even if it fails (we can see that from the old code too: when we try to resume we also check against "entered_postcopy" variable). So further we do this: - in postcopy_start(), we don't update vm_old_running since useless - in migration_thread(), we don't need to check entered_postcopy when resume, since it's only used for precopy. Comment this out too for that variable definition. Reviewed-by: Juan Quintela <quintela@redhat.com> Signed-off-by: Peter Xu <peterx@redhat.com> Signed-off-by: Juan Quintela <quintela@redhat.com>

2018-01-15migration: add postcopy total blocktime into query-migrateAlexey Perevalov
Postcopy total blocktime is available on destination side only. But query-migrate was possible only for source. This patch adds ability to call query-migrate on destination. To be able to see postcopy blocktime, need to request postcopy-blocktime capability. The query-migrate command will show following sample result: {"return": "postcopy-vcpu-blocktime": [115, 100], "status": "completed", "postcopy-blocktime": 100 }} postcopy_vcpu_blocktime contains list, where the first item is the first vCPU in QEMU. This patch has a drawback, it combines states of incoming and outgoing migration. Ongoing migration state will overwrite incoming state. Looks like better to separate query-migrate for incoming and outgoing migration or add parameter to indicate type of migration.

2017-07-24migration: Use JSON null instead of "" to reset parameter to defaultMarkus Armbruster
migrate-set-parameters sets migration parameters according to is arguments like this: * Present means "set the parameter to this value" * Absent means "leave the parameter unchanged" * Except for parameters tls_creds and tls_hostname, "" means "reset the parameter to its default value The first two are perfectly normal: presence of the parameter makes the command do something. The third one overloads the parameter with a second meaning. The overloading is *implicit*, i.e. it's not visible in the types. Works here, because "" is neither a valid TLS credentials ID, nor a valid host name. Pressing argument values the schema accepts, but are semantically invalid, into service to mean "reset to default" is not general, as suitable invalid values need not exist. I also find it ugly. To clean this up, we could add a separate flag argument to ask for "reset to default", or add a distinct value to @tls_creds and @tls_hostname. This commit implements the latter: add JSON null to the values of @tls_creds and @tls_hostname, deprecate "". Because we're so close to the 2.10 freeze, implement it in the stupidest way possible: have qmp_migrate_set_parameters() rewrite null to "" before anything else can see the null. The proper way to do it would be rewriting "" to null, but that requires fixing up code to work with null. Add TODO comments for that.

2017-07-24migration: Unshare MigrationParameters struct for nowMarkus Armbruster
Commit de63ab6 "migrate: Share common MigrationParameters struct" reused MigrationParameters for the arguments of migrate-set-parameters, with the following rationale: It is rather verbose, and slightly error-prone, to repeat the same set of parameters for input (migrate-set-parameters) as for output (query-migrate-parameters), where the only difference is whether the members are optional. We can just document that the optional members will always be present on output, and then share a common struct between both commands. The next patch can then reduce the amount of code needed on input. I need to unshare them to correct a design flaw in a stupid, but minimally invasive way, in the next commit. We can restore the sharing when we redo that patch in a less stupid way. Add a suitable TODO comment. Note that I revert only the sharing part of commit de63ab6, not the part that made the members of query-migrate-parameters' result optional. The schema (and thus introspection) remains inaccurate for query-migrate-parameters. If we decide not to restore the sharing, we should revert that part, too.

Abstract helper function to check migration capabilities (from the old qmp_migrate_set_capabilities). Prepare to be used somewhere else.
