[Qemu-devel] [Bug 1320030] [NEW] Qemu 2.0.0 with display=gtk hangs |

Public bug reported:
When qemu 2.0.0 is started, compiled with gtk, communications between
the emulator process and the gtk "wrapper" window hang, and the emulator
hangs typically before the bios finishes initializing, and if boot
menu=on is selected, even if it gets to this point, keyboard input is
not accepted to the emulator process. Switching to the session console
in the window header yeilds a fully functional console with zero input
issues, indicating that the overall process is getting keyboard data,
just not cleanly passing it to the emulator. A "system_reset" in the
console will typically result in a bit more execution of the emulator,
and then a subsequent hang at a later point. When the hang occurs, CPU
useage pegs at 100%, and when I strace the process, I get typically
20,000 lines in the trace in about 2 seconds, 90% of which is
repetitive:

The host system has an average load as of this test of .38, and is 8 2.33GHz
Xeon cores, and 8GB RAM with a 3.10.17 kernel, and nowhere near swapping . . .
(Distro is slackware 14.1, FWIW)
The above was generated with the command:
strace qemu-system-x86_64 linux-0.2.img -cpu Westmere -k en-us -machine
accel=kvm
This occurs with any cpu, with or without the "-k" (I had seen some
reports that some probs in the GTK build were resolved by this option -
no joy here) and with and without the "accell=kvm" (again tried based on
other found bugs/solutions.).
Thus:
strace qemu-system-x86_64 linux0.2.img
Behaves identically, and disabling serial and parallel also has zero
impact. If I run with "-display=sdl" then the image boots perfects, as
is also the case if I build qemu with --disable-gtk.
This situation is identical on a remote display, and also in 1.7.1.
