Verification of this bug is blocked by bug 736975. According to: https://bugzilla.redhat.com/show_bug.cgi?id=736975#c8 Bug 736975 has been fixed. Reproduce and verify using steps in: https://bugzilla.redhat.com/show_bug.cgi?id=726020#c7 Since from qemu 160, all version suffers from bug 736975, cannot reproduce this as a contrast, just verify the patch. Verify on qemu-kvm-0.12.1.2-2.193.el6.x86_64: used free buffers/cached 181 7281 0/6 <---before start qemu 735 6726 0/9 <---start qemu 731 6730 0/9 <---after hotplug/unplug 300 times 182 7279 0/6 <---after exit qemu According to above results, the patch works fine, verified. However, there is another issue, once i did 300 times hotplug/unplug and check the result next morning, the used/free memory are 914/6547, i did two times more and check the result immediately after it finished, it looks like above one, seems when idle, qemu-kvm has memory leak? I will investigate this further. Any advice please let me know.
