From 2b58a8b9631f25f0ddc19fbed0fd5bfff3bb5f41 Mon Sep 17 00:00:00 2001 From: Steve Sistare Date: Wed, 3 Jan 2024 12:05:41 -0800 Subject: [PATCH] tests/qtest: postcopy migration with suspend Add a test case to verify that the suspended state is handled correctly by live migration postcopy. The test suspends the src, migrates, then wakes the dest.
