2015-11-10Move page_size_init earlierDr. David Alan Gilbert
The HOST_PAGE_ALIGN macros don't work until the page size variables have been set up; later in postcopy I use those macros in the RAM code, and it can be triggered using -object. Fix this by initialising page_size_init() earlier - it's currently initialised inside the accelerators, move it up into vl.c.

2015-10-12netfilter: add a netbuffer filterYang Hongyang
This filter is to buffer/release packets. Can be used when using MicroCheckpointing or other Remus like VM FT solutions. You can also use it to crudely simulate network delay. Doesn't actually delay individual packets, but batches them together, which is a delay of sorts. Usage: -netdev tap,id=bn0 -object filter-buffer,id=f0,netdev=bn0,queue=rx,interval=1000 NOTE: Interval is in microseconds, it can't be omitted currently, and can't be 0.

2015-10-02vl: Add another sanity check to smp_parse() functionThomas Huth
The code in smp_parse already checks the topology information for sockets * cores * threads < cpus and bails out with an error in that case. However, it is still possible to supply a bad configuration the other way round, e.g. with: qemu-system-xxx -smp 4,sockets=1,cores=4,threads=2 QEMU then still starts the guest, with topology configuration that is rather incomprehensible and likely not what the user wanted.

2015-07-07migration: create new section to store global stateJuan Quintela
This includes a new section that for now just stores the current qemu state. Right now, there are only one way to control what is the state of the target after migration. - If you run the target qemu with -S, it would start stopped. - If you run the target qemu without -S, it would run just after migration finishes. The problem here is what happens if we start the target without -S and there happens one error during migration that puts current state as -EIO. Migration would ends (notice that the error happend doing block IO, network IO, i.e. nothing related with migration), and when migration finish, we would just "continue" running on destination, probably hanging the guest/corruption data, whatever.

2015-07-07crypto: introduce new module for computing hash digestsDaniel P. Berrange
Introduce a new crypto/ directory that will (eventually) contain all the cryptographic related code. This initially defines a wrapper for initializing gnutls and for computing hashes with gnutls. The former ensures that gnutls is guaranteed to be initialized exactly once in QEMU regardless of CLI args. The block quorum code currently fails to initialize gnutls so it only works by luck, if VNC server TLS is not requested. The hash APIs avoids the need to litter the rest of the code with preprocessor checks and simplifies callers by allocating the correct amount of memory for the requested hash.

2015-07-07vl: move rom_load_all after machine init doneEric Auger
On ARM, commit ac9d32e39664e060cd1b538ff190980d57ad69e4 postponed the memory preparation for boot until the machine init done notifier. This has for consequence to insert ROM at machine init done time. However the rom_load_all function stayed called before the ROM are inserted. As a consequence the rom_load_all function does not do everything it is expected to do, on ARM. It currently registers the ROM reset notifier but does not iterate through the registered ROM list. the isrom field is not set properly. This latter is used to report info in the monitor and also to decide whether the rom->data can be freed on ROM reset notifier. To fix that regression the patch moves the rom_load_all call after machine init done. We also take the opportunity to rename the rom_load_all function into rom_check_and_resgister_reset() and integrate the rom_load_done in it.

Results in nicer error messages. Before this patch: Invalid GTK option string: gtk,lirum-larum After: qemu-system-x86_64: -display gtk,lirum-larum: Invalid GTK option string Of course, the thing ought to use QemuOpts instead of parsing by hand.

qerror_report() is a transitional interface to help with converting existing monitor commands to QMP. It should not be used elsewhere. Replace by error_report() in initial startup helpers parse_sandbox() and parse_add_fd().

2015-06-22QemuOpts: Wean off qerror_report_err()Markus Armbruster
qerror_report_err() is a transitional interface to help with converting existing monitor commands to QMP. It should not be used elsewhere. The only remaining user in qemu-option.c is qemu_opts_parse(). Is it used in QMP context? If not, we can simply replace qerror_report_err() by error_report_err(). The uses in qemu-img.c, qemu-io.c, qemu-nbd.c and under tests/ are clearly not in QMP context. The uses in vl.c aren't either, because the only QMP command handlers there are qmp_query_status() and qmp_query_machines(), and they don't call it. Remaining uses: * drive_def(): Command line -drive and such, HMP drive_add and pci_add * hmp_chardev_add(): HMP chardev-add * monitor_parse_command(): HMP core * tmp_config_parse(): Command line -tpmdev * net_host_device_add(): HMP host_net_add * net_client_parse(): Command line -net and -netdev * qemu_global_option(): Command line -global * vnc_parse_func(): Command line -display, -vnc, default display, HMP change, QMP change. Bummer. * qemu_pci_hot_add_nic(): HMP pci_add * usb_net_init(): Command line -usbdevice, HMP usb_add Propagate errors through qemu_opts_parse(). Create a convenience function qemu_opts_parse_noisily() that passes errors to error_report_err(). Switch all non-QMP users outside tests to it. That leaves vnc_parse_func(). Propagate errors through it. Since I'm touching it anyway, rename it to vnc_parse().

2015-06-19vl: Create (most) objects before creating chardev backendsDaniel P. Berrange
Some types of object must be created before chardevs, other types of object must be created after chardevs. As such there is no option but to create objects in two phases. This takes the decision to create as many object types as possible right away before anyother backends are created, and only delay creation of those few which have an explicit dependency on the chardevs. Hopefully the set which need delaying will remain small over time.
