* qemu-log: default to stderr for logging outputPeter Maydell2013-02-261-10/+8Star
| | | | | | | | | | | | | | | | | | | | | | | | | Switch the default for qemu_log logging output from "/tmp/qemu.log" to stderr. This is an incompatible change in some sense, but logging is mostly used for debugging purposes so it shouldn't affect production use. The previous behaviour can be obtained by adding "-D /tmp/qemu.log" to the command line. This change requires us to: * update all the documentation/help text (we take the opportunity to smooth out minor inconsistencies between the phrasing in linux-user/bsd-user/system help messages) * make linux-user and bsd-user defer to qemu-log for the default logging destination rather than overriding it themselves * ensure that all logfile closing is done via qemu_log_close() and that that function doesn't close stderr as well as the obvious change to the behaviour of do_qemu_set_log() when no logfile name has been specified.

* linux-user: bsd-user: Don't reset X86CPU twiceAndreas Färber2013-02-011-1/+1
| | | | | | | | | | | | | Since commit 65dee38052597b6285eb208125369f01b29ba6c1 (target-i386: move cpu_reset and reset callback to cpu.c) the x86 CPU is reset through cpu_init() but was still reset immediately after in linux-user and bsd-user. Clean this up. Similarly in linux-user/syscall.c it is also reset after cpu_copy(). But that's a bug of its own, fixing which poses a semantic change.

* Support 'help' as a synonym for '?' in command line optionsPeter Maydell2012-08-021-2/+2
| | | | | | | | | | | | | | | | | | | | | | | | | | For command line options which permit '?' meaning 'please list the permitted values', add support for 'help' as a synonym, by abstracting the check out into a helper function. This change means that in some cases where we were being lazy in our string parsing, "?junk" will now be rejected as an invalid option rather than being (undocumentedly) treated the same way as "?". Update the documentation to use 'help' rather than '?', since '?' is a shell metacharacter and thus prone to fail confusingly if there is a single character filename in the current working directory and the '?' has not been escaped. It's therefore better to steer users towards 'help', though '?' is retained for backwards compatibility. We do not, however, update the output of the system emulator's -help (or any documentation autogenerated from the qemu-options.hx which is the source of the -help text) because libvirt parses our -help output and will break. At a later date when QEMU provides a better interface so libvirt can avoid having to do this, we can update the -help text too.
