first time found this bug in qemu-kvm-0.12.1.2-2.138.el6 ,refer bz621484 . This is an expected regression, as the fix for the bug 621484 was buggy. This will be resolved upstream first. This is noted in the upstream feature known bugs section: http://wiki.qemu.org/Features/ChardevFlowControl#Known_bugs Gerd, do you recall if this was fixed? IIRC we were blocking on main loop to switch to poll() instead of select() so that qemu would recognise backend disconnects. Hmm, not sure. From a brief look at the code it looks like main-loop.c still uses select even though it uses glib poll bits somehow ... *** This bug has been marked as a duplicate of bug 702271 *** |
