Hi, the bug was introduced upstream by commit c2e50e3d11a0bf4c973cc30478c1af0f2d5f8e81 (thread-pool: avoid per-thread-pool EventNotifier). Until that commit, the code in async.c is safe because bottom halves are never used across threads. Thus: - the qemu-kvm package, as well as the qemu-kvm-rhev-1.5.3 package is immune from the bug. - the qemu-kvm-rhev-2.1.2 package has the bug - the qemu-kvm-rhev-2.3.0 package has the above patch and the fix, and thus is also immune from the bug Please close the bug if you are only interested in the 1.5.3 versions, or request the rhel-7.1.z flag if you are interested in a fix for qemu-kvm-rhev-2.1.2.
I appreciate your kind support. We know the bug does not occur in qemu-kvm 1.5.3 versions by your answer. We plan to use 1.5.3 versions, therefore I want to close this bug report as NOTABUG. Sorry, I couldn't find how to close bug. Can you please teach me how to close bug ?

Just as you say, I didn't probably have permission. I couldn't change a dropdown control labelled "Status:" at last time.
