2015-02-26qemu-img: Suppress unhelpful extra errors in convert, amendMarkus Armbruster
img_convert() and img_amend() use qemu_opts_do_parse(), which reports errors with qerror_report_err(). Its error messages aren't helpful here, the caller reports one that actually makes sense. Reproducer: $ qemu-img convert -o backing_format=raw in.img out.img qemu-img: Invalid parameter 'backing_format' qemu-img: Invalid options for file format 'raw' To fix, propagate errors through qemu_opts_do_parse(). This lifts the error reporting into callers. Drop it from img_convert() and img_amend(), keep it in qemu_chr_parse_compat(), bdrv_img_create(). Since I'm touching qemu_opts_do_parse() anyway, write a function comment for it. Signed-off-by: Markus Armbruster <armbru@redhat.com> Reviewed-by: Eric Blake <eblake@redhat.com>

2015-02-26QemuOpts: Drop qemu_opt_set(), rename qemu_opt_set_err(), fix useMarkus Armbruster
qemu_opt_set() is a wrapper around qemu_opt_set() that reports the error with qerror_report_err(). Most of its users assume the function can't fail. Make them use qemu_opt_set_err() with &error_abort, so that should the assumption ever break, it'll break noisily. Just two users remain, in util/qemu-config.c. Switch them to qemu_opt_set_err() as well, then rename qemu_opt_set_err() to qemu_opt_set(). Signed-off-by: Markus Armbruster <armbru@redhat.com> Reviewed-by: Eric Blake <eblake@redhat.com>

2015-02-18usb: Suppress bogus error when automatic usb-hub creation failsMarkus Armbruster
USBDevice's realize method usb_qdev_realize() automatically creates a usb-hub when only one port is left. Creating devices in realize methods is questionable, but works. If usb-hub creation fails, an error is reported to stderr, but the failure is otherwise ignored. We then create the actual device using the last port, which may well succeed. Example: $ qemu -nodefaults -S -display none -machine usb=on -monitor stdio QEMU 2.2.50 monitor - type 'help' for more information (qemu) device_add usb-mouse [Repeat 36 times] (qemu) info usb Device 0.0, Port 1, Speed 12 Mb/s, Product QEMU USB Mouse Device 0.0, Port 2, Speed 12 Mb/s, Product QEMU USB Hub Device 0.0, Port 2.1, Speed 12 Mb/s, Product QEMU USB Mouse [More mice and hubs omitted...] Device 0.0, Port 2.8.8.8.8.7, Speed 12 Mb/s, Product QEMU USB Mouse (qemu) device_add usb-mouse usb hub chain too deep Failed to initialize USB device 'usb-hub' (qemu) info usb [...] Device 0.0, Port 2.8.8.8.8.7, Speed 12 Mb/s, Product QEMU USB Mouse Device 0.0, Port 2.8.8.8.8.8, Speed 12 Mb/s, Product QEMU USB Mouse Despite the "Failed" message, the command actually succeeded. In QMP, it's worse. When adding the 37th mouse via QMP, the command fails with {"error": {"class": "GenericError", "desc": "usb hub chain too deep"}} Additionally, "Failed to initialize USB device 'usb-hub'" is reported on stderr. Despite the command failure, the device was created. This is wrong. Fix by avoiding qdev_init() for usb-hub creation, so we can ignore errors cleanly.

2015-02-18usb: Improve -usbdevice error reporting a bitMarkus Armbruster
Most LegacyUSBFactory usbdevice_init() methods realize with qdev_init_nofail(), even though their caller usbdevice_create() can handle failure. Okay if it really can't fail (I didn't check), but somewhat brittle. usb_msd_init() and usb_bt_init() call qdev_init(). The latter additionally reports an error when qdev_init() fails. Realization failure produces multiple error reports: a specific one from qdev_init(), and generic ones from usb_bt_init(), usb_create_simple(), usbdevice_create() and usb_parse(). Remove realization from the usbdevice_init() methods. Realize in usbdevice_create(), and produce exactly one error message there. You still get another one from usb_parse().

monitor_handle_fd_param() is a wrapper around monitor_handle_fd_param2() that feeds errors to qerror_report_err() instead of returning them. qerror_report_err() is inappropriate in many contexts. monitor_handle_fd_param() looks simpler than monitor_handle_fd_param2(), which tempts use. Remove the temptation: drop the wrapper and open-code the (trivial) error handling instead. Replace the open-coded qerror_report_err() by error_report_err() in places that already use error_report().

2015-02-18vhost-scsi: Improve error reporting for invalid vhostfdMarkus Armbruster
We get two error messages: one from monitor_handle_fd_param2(), and another one from vhost_scsi_realize(). The second one gets suppressed in QMP context. That's because monitor_handle_fd_param() calls qerror_report_err(). Calling qerror_report_err() is always inappropriate in realize methods, because it doesn't return the Error object. It either reports the error to stderr or the human monitor, or it stores it in the QMP monitor, where it makes the QMP command fail even when the realize method ignores the error and succeeds. Fortunately, vhost_scsi_realize() doesn't do that. Fix by switching to monitor_handle_fd_param2(). Signed-off-by: Markus Armbruster <armbru@redhat.com> Acked-by: Paolo Bonzini <pbonzini@redhat.com>
2015-02-17qemu-ga-win: Fail loudly on bare 'set-time'Michal Privoznik
The command is not implemented correctly yet. The documentation allows to not pass any value to set, in which case the time is re-read from RTC. However, reading CMOS on Windows is not trivial to implement. So instead of pretending we've set the correct time, fail explicitly.

2015-02-17qga: implement qmp_guest_get_memory_block_info() for Linux with sysfszhanghailiang
This conveys general information about guest memory blocks. Currently, just the memory block size. The size of a memory block is architecture dependent, it represents the logical unit upon which memory online/offline operations are to be performed.

Introduce three new guest commands: guest-get-memory-blocks, guest-set-memory-blocks, guest-get-memory-block-size. With these three commands, we can support online/offline guest's memory block (logical memory hotplug/unplug) as required from host.

2015-02-16qga: implement file commands for Windows guestOlga Krishtal
The following commands are implemented: - guest_file_open - guest_file_close - guest_file_write - guest_file_read - guest_file_seek - guest_file_flush Motivation is quite simple: Windows guests should be supported with the same set of features as Linux one. Also this patch is a prerequisite for Windows guest-exec command support. Signed-off-by: Olga Krishtal <okrishtal@parallels.com> Signed-off-by: Denis V.

2015-02-16utils: drop strtok_r from envlist_parseOlga Krishtal
The problem is that mingw 4.9.1 fails to compile the code with the following warning: /mingw/include/string.h:88:9: note: previous declaration of 'strtok_r' was here char *strtok_r(char * __restrict__ _Str, const char * __restrict__ _Delim, char ** __restrict__ __last); /include/sysemu/os-win32.h:83:7: warning: redundant redeclaration of 'strtok_r' [-Wredundant-decls] char *strtok_r(char *str, const char *delim, char **saveptr); The problem is that compiles just fine on previous versions of mingw. Compiler version check here is not a good idea. Though fortunately strtok_r is used only once in the code and we could simply rewrite the code without it.
