2015-06-22QemuOpts: Wean off qerror_report_err()Markus Armbruster1-38/+65
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. Berrange1-1/+39
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.

2015-06-19semihosting: add --semihosting-config arg sub-argumentLeon Alrae1-0/+66
Add new "arg" sub-argument to the --semihosting-config allowing the user to pass multiple input arguments separately. It is required for example by UHI semihosting to construct argc and argv. Also, update ARM semihosting to support new option (at the moment it is the only target which cares about arguments). If the semihosting is enabled and no semihosting args have been specified, then fall back to -kernel/-append. The -append string is split on whitespace before initializing semihosting.argv[1..n]; this is different from what QEMU MIPS machines' pseudo-bootloaders do (i.e. argv[1] contains the whole -append), but is more intuitive from UHI user's point of view and Linux kernel just does not care as it concatenates argv[1..n] into single cmdline string anyway.

2015-06-17qemu-log: Open file for logging when specifiedPranith Kumar1-8/+5
qemu-log defaults to stderr when there is no '-D' option mentioned on command line. When '-D' option is specified, we also need to specify '-d' option for it to use the specified logfile. When using monitor to enable logging this is troublesome since there will be no '-d' option because of which monitor dumps the logs to stderr. Fix this by opening the log file when '-D' is specified on the command line. Also fix an ancient comment which does not hold true since changing location and log level has now been streamlined.

Failure to create an object with -object is a fatal error. However, we delay the actual exit until all -object are processed. On the one hand, this permits detection of genuine additional errors. On the other hand, it can muddy the waters with uninteresting additional errors, e.g. when a later -object tries to reference a prior one that failed. We generally stop right on the first bad option, so do that for -object as well. Signed-off-by: Markus Armbruster <armbru@redhat.com> Reviewed-by: Eric Blake <eblake@redhat.com>

2015-03-03bootdevice: check boot order argument validation before vm runningGonglei1-14/+22
Either 'once' option or 'order' option can take effect for -boot at the same time, that is say initial startup processing can check only one. And pc.c's set_boot_dev() fails when its boot order argument is invalid. This patch provide a solution fix this problem: 1. If "once" is given, register reset handler to restore boot order. 2. Pass the normal boot order to machine creation. Should fail when the normal boot order is invalid. 3. If "once" is given, set it with qemu_boot_set(). Fails when the once boot order is invalid. 4. Start the machine. 5. On reset, the reset handler calls qemu_boot_set() to restore boot order. Should never fail.

2015-02-26QemuOpts: Drop qemu_opt_set(), rename qemu_opt_set_err(), fix useMarkus Armbruster1-33/+40
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>
