From fd040174ac7c302365c1d6dc5646f957972d67d6 Mon Sep 17 00:00:00 2001 From: Jeff Cody Date: Wed, 30 Apr 2014 10:55:10 -0400 Subject: [PATCH] block: qemu-iotests - test for live migration This is an initial, simple live migration test from one running VM to another, using monitor commands. This is also an example of using the new common.qemu functions for controlling multiple running qemu instances, for tests that need a live qemu vm.
