From 0811efa2bcaae69e59fe09432083224e77eafa1d Mon Sep 17 00:00:00 2001 Message-Id: <0811efa2bcaae69e59fe09432083224e77eafa1d@dist-git> From: Jiri Denemark Date: Wed, 5 Apr 2017 10:24:47 +0200 Subject: [PATCH] qemu: Don't reset TLS in qemuMigrationRun Finished qemuMigrationRun does not mean the migration itself finished (it might have just switched to post-copy mode). While resetting TLS parameters is probably OK at this point even if migration is still running, we want to consolidate the code which resets various migration parameters. Thus qemuMigrationResetTLS will be called from the Confirm phase (or at the end of the Perform phase in case of v2 protocol), when migration is either canceled or finished.
