I have seen a large number of failures of production qemu-kvm virtual
machines with segfaults in the VNC code. (Thread rooted at

Avi pointed out Gerd's patch 198a00:


which I backported <address@hidden>:


This has massively reduced the crash rate of qemu-kvm processes across our
clusters, although I still do a see a (much rarer) vnc-related segfault in

Although these use-after-free problems were seen in qemu-kvm, the code (and
patch) are identical in standard qemu so I'd strongly recommend this
backport of Gerd's patch for qemu-stable 0.10.7.
