2014-09-26monitor: Reset HMP mon->rs in CHR_EVENT_OPENStratos Psomadakis1-0/+1
Commit cdaa86a54 ("Add G_IO_HUP handler for socket chardev") exposed a bug in the way the HMP monitor handles its command buffer. When a client closes the connection to the monitor, tcp_chr_read() will detect the G_IO_HUP condition and call tcp_chr_disconnect() to close the server-side connection too. Due to the fact that monitor reads 1 byte at a time (for each tcp_chr_read()), the monitor readline state / buffers might contain junk (i.e. a half-finished command). Thus, without calling readline_restart() on mon->rs in CHR_EVENT_OPEN, future HMP commands will fail.

2014-09-26kvm/valgrind: don't mark memory as initializedChristian Borntraeger2-9/+1
since commit 7dda5dc82a77 ("migration: initialize RAM to zero") the guest memory is defined zero. No need to call valgrind on guest memory. This reverts commit 62fe83318d2f ("qemu: Use valgrind annotations to mark kvm guest memory as defined") thus speeding up kvm start if <includedir>/valgrind/valgrind.h is available.

2014-09-26po: fix conflict with %.mo rule in rules.makPaolo Bonzini1-3/+3
po/Makefile includes rules.mak to use the nice quiet-command macro. However, this also brings in a %.mo rule that breaks "make build". Put our own rule before the include, so that it has precedence.

2014-09-26kvmvapic: fix migration when VM paused and when not running WindowsPavel Dovgalyuk1-2/+9
This patch fixes migration by extending do_vapic_enable function. This function called vapic_enable which read cpu number from the guest memory. When cpu number could not be read, vapic was not enabled while loading the VM state. This patch adds required code for cpu_number=0 to do_vapic_enable function, because it is called only when cpu_number=0.

2014-09-26main-loop.c: Handle SIGINT, SIGHUP and SIGTERM synchronouslyPeter Maydell1-0/+3
Add the termination signals SIGINT, SIGHUP and SIGTERM to the list of signals which we handle synchronously via a signalfd. This avoids a race condition where if we took the SIGTERM in the middle of qemu_shutdown_requested: int r = shutdown_requested; [SIGTERM here...] shutdown_requested = 0; then the setting of the shutdown_requested flag by termsig_handler() would be lost and QEMU would fail to shut down. This was causing 'make check' to hang occasionally.

Install the ./trace-events file into the data directory. This file contains the list of trace events that were built into QEMU at compile-time. The file is a handy reference for the set of trace events that the QEMU binary was built with. It is also needed by the simpletrace.py tool that parses binary trace data either emitted from QEMU when built with --enable-trace-backend=simple or by the SystemTap simpletrace script that QEMU provides.
