2017-07-10migration: fix handling for --only-migratablePeter Xu1-1/+0
MigrateState object is not ready at that time, so we'll get an assertion. Use qemu_global_option() instead.

2017-06-28migration: hmp: dump globalsPeter Xu1-0/+1
Now we have some globals that can be configured for migration. Dump them in HMP info migration for better debugging. (we can also use this to monitor whether COMPAT fields are applied correctly on compatible machines) Reviewed-by: Juan Quintela <quintela@redhat.com> Signed-off-by: Peter Xu <peterx@redhat.com> Message-Id: <1498536619-14548-11-git-send-email-peterx@redhat.com> Signed-off-by: Juan Quintela <quintela@redhat.com>
2017-06-28migration: move skip_section_footersPeter Xu1-1/+0
Move it into MigrationState, revert its meaning and renaming it to send_section_footer, with a property bound to it. Same trick is played like previous patches. Removing savevm_skip_section_footers().

2017-06-28migration: move skip_configuration outPeter Xu1-1/+0
It was in SaveState but now moved to MigrationState altogether, reverted its meaning, then renamed to "send_configuration". Again, using HW_COMPAT_2_3 for old PC/SPAPR machines, and accel_register_prop() for xen_init(). Removing savevm_skip_configuration().

2017-06-28migration: move only_migratable to MigrationStatePeter Xu1-0/+2
One less global variable, and it does only matter with migration. We keep the old "--only-migratable" option, but also now we support: -global migration.only-migratable=true Currently still keep the old interface. Hmm, now vl.c has no way to access migrate_get_current(). Export a function for it to setup only_migratable.

2017-06-28migration: let MigrationState be a qdevPeter Xu1-0/+1
Let the old man "MigrationState" join the object family. Direct benefit is that we can start to use all the property features derived from current QDev, like: HW_COMPAT_* bits, command line setup for migration parameters (so will never need to set them up each time using HMP/QMP, this is really, really attractive for test writters), etc. I see no reason to disallow this happen yet. So let's start from this one, to see whether it would be anything good. Now we init the MigrationState struct statically in main() to make sure it's initialized after global properties are applied, since we'll use them during creation of the object. No functional change at all.
