[Qemu-devel] [PULL 01/22] hmp: migrate command (without -d) now blocks correctly

[Luiz Capitulino]

From: Soramichi AKIYAMA <address@hidden>

This patch fixes a timing issue that migrate command (without -d) does not
block in some cases.

The original version of hmp.c:hmp_migrate_status_cb checks if the
migration status is 'active' or not to detect the completion of a migration.

However, if this function is executed when the migration status is stil
'setup' (the status before 'active'), migration command returns
immediately even if the user does not specify -d option.
