2014-09-22async: aio_context_new(): Handle event_notifier_init failureChrysostomos Nanakos
On a system with a low limit of open files the initialization of the event notifier could fail and QEMU exits without printing any error information to the user. The problem can be easily reproduced by enforcing a low limit of open files and start QEMU with enough I/O threads to hit this limit. The same problem raises, without the creation of I/O threads, while QEMU initializes the main event loop by enforcing an even lower limit of open files. This commit adds an error message on failure: # qemu [...] -object iothread,id=iothread0 -object iothread,id=iothread1 qemu: Failed to initialize event notifier: Too many open files in system Signed-off-by: Chrysostomos Nanakos <cnanakos@grnet.gr> Signed-off-by: Stefan Hajnoczi <stefanha@redhat.com>

Accroding to the machine option, q35 will initialize the Intel IOMMU and use pci_setup_iommu() to setup q35_host_dma_iommu() as the IOMMU function for the pci bus. 3. q35_host_dma_iommu() will return different address space according to the bus_num and devfn of the device.

2014-07-01trace: add qemu_system_powerdown_request and qemu_system_shutdown_request ↵Yang Zhiyong
trace events We have the experience that the guest doesn't stop successfully though it was instructed to shut down. The root cause may be not in QEMU mostly. However, QEMU is often suspected at the beginning just because the issue occurred in virtualization environment. Therefore, we need to affirm that QEMU received the shutdown request and raised ACPI irq from "virsh shutdown" command, virt-manger or stopping QEMU process to the VM . So that we can affirm the problems was belonged to the Guset OS rather than the QEMU itself. When we stop guests by "virsh shutdown" command or virt-manger, or stopping QEMU process, qemu_system_powerdown_request() or qemu_system_shutdown_request() is called. Then the below functions in main_loop_should_exit() of Vl.c are called roughly in the following order. if (qemu_powerdown_requested()) qemu_system_powerdown() monitor_protocol_event(QEVENT_POWERDOWN, NULL) OR if(qemu_shutdown_requested()} monitor_protocol_event(QEVENT_SHUTDOWN, NULL); The tracepoint of monitor_protocol_event() already exists, but no tracepoints are defined for qemu_system_powerdown_request() and qemu_system_shutdown_request(). So this patch adds two tracepoints for the two functions. We believe that it will become much easier to isolate the problem mentioned above by these tracepoints.

2014-06-23migration: dump vmstate info as a json file for static analysisAmit Shah
This commit adds a new command, '-dump-vmstate', that takes a filename as an argument. When executed, QEMU will dump the vmstate information for the machine type it's invoked with to the file, and quit. The JSON-format output can then be used to compare the vmstate info for different QEMU versions, specifically to test whether live migration would break due to changes in the vmstate data. A Python script that compares the output of such JSON dumps is included in the following commit.

2014-06-23pc & q35: Add new machine opt max-ram-below-4gDon Slutz
This is a pc & q35 only machine opt. If you add enough PCI devices then all mmio for them will not fit below 4G which may not be the layout the user wanted. This allows you to increase the below 4G address space that PCI devices can use (aka decrease ram below 4G) and therefore in more cases not have any mmio that is above 4G. For example using "-machine pc,max-ram-below-4g=2G" on the command line will limit the amount of ram that is below 4G to 2G.

2014-06-18vl.c: daemonize before guest memory allocationIgor Mammedov
memory allocated for guest before QEMU is daemonized and then mapped later in guest's address space after it is daemonized, leads to EPT violation and QEMU aborts. To avoid this and similar issues switch to daemonized mode early before applying/processing other options.

2014-06-09trace: Multi-backend tracingLluís Vilanova
Adds support to compile QEMU with multiple tracing backends at the same time. For example, you can compile QEMU with: $ ./configure --enable-trace-backends=ftrace,dtrace Where 'ftrace' can be handy for having an in-flight record of events, and 'dtrace' can be later used to extract more information from the system. This patch allows having both available without recompiling QEMU. Signed-off-by: Lluís Vilanova <vilanova@ac.upc.edu> Signed-off-by: Stefan Hajnoczi <stefanha@redhat.com>

This can help a user understand why -global was ignored. For example: with "-vga cirrus"; "-global vga.vgamem_mb=16" is just ignored when "-global cirrus-vga.vgamem_mb=16" is not.
