2012-08-02Support 'help' as a synonym for '?' in command line optionsPeter Maydell
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.

2012-07-20ram: save_live_setup() we don't need to synchronize the dirty bitmap.Juan Quintela
1st: we were synchonizing the dirty bitmap before calling memory_global_dirty_log_start(). 2nd: We are marking all pages as dirty anywhere, no reason to go through all the bitmap to "mark" dirty same pages twice. So, call removed. Signed-off-by: Juan Quintela <quintela@redhat.com>
2012-07-20ram: iterate phaseJuan Quintela
We only need to synchronize the bitmap when the number of dirty pages is low. Not every time that we call the function. Signed-off-by: Juan Quintela <quintela@redhat.com>
2012-07-20ram: save_live_complete() only do one loopJuan Quintela
We were doing the same loop that stage2, and a new one for stage3. We only need the one for stage3. Signed-off-by: Juan Quintela <quintela@redhat.com>
2012-07-20ram: save_live_setup() don't need to sent pagesJuan Quintela
We should send pages on interate phase, not in setup one. This was a "bug". Just removing the loop does what we want. Tested that it works with current ram_load(). Signed-off-by: Juan Quintela <quintela@redhat.com>
2012-07-20savevm: split save_live into stage2 and stage3Juan Quintela
We split it into 2 functions, foo_live_iterate, and foo_live_complete. At this point, we only remove the bits that are for the other stage, functionally this is equivalent to previous code. Signed-off-by: Juan Quintela <quintela@redhat.com>
2012-07-20savevm: split save_live_setup from save_live_stateJuan Quintela
This patch splits stage 1 to its own function for both save_live users, ram and block. It is just a copy of the function, removing the parts of the other stages. Optimizations would came later. Signed-off-by: Juan Quintela <quintela@redhat.com>

2012-06-29Maintain the number of dirty pagesJuan Quintela
Calculate the number of dirty pages takes a lot on hosts with lots of memory. Just maintain how many pages are dirty. Signed-off-by: Juan Quintela <quintela@redhat.com>
2012-06-29Exit loop if we have been there too longJuan Quintela
Checking each 64 pages is a random magic number as good as any other. We don't want to test too many times, but on the other hand, qemu_get_clock_ns() is not so expensive either. We want to be sure that we spent less than 50ms (half of buffered_file timer), if we spent more than 100ms, all the accounting got wrong. Signed-off-by: Juan Quintela <quintela@redhat.com>
2012-06-29Only calculate expected_time for stage 2Juan Quintela
ram_save_remaining() is an expensive operation when there is a lot of memory. So we only call the function when we need it. Signed-off-by: Juan Quintela <quintela@redhat.com>

2012-05-29arch_init: Fix AltiVec build on Darwin/ppcAndreas Färber
Commit f29a56147b66845914d0a645bf9b4c5bb9a6af57 (implement -no-user-config command-line option (v3)) introduced uses of bool in arch_init.c. Shortly before that usage is support code for AltiVec (conditional to __ALTIVEC__). GCC's altivec.h may in a !__APPLE_ALTIVEC__ code path redefine bool, leading to type mismatches. altivec.h recommends to #undef for C++ compatibility, but doing so in C leads to bool remaining undefined. Fix by redefining bool to _Bool as mandated for stdbool.h by POSIX. Signed-off-by: Andreas Färber <andreas.faerber@web.de> Reviewed-by: Paolo Bonzini <pbonzini@redhat.com>

2012-03-15Purge migration of (almost) everything to do with monitorsLuiz Capitulino
The Monitor object is passed back and forth within the migration/savevm code so that it can print errors and progress to the user. However, that approach assumes a HMP monitor, being completely invalid in QMP. This commit drops almost every single usage of the Monitor object, all monitor_printf() calls have been converted into DPRINTF() ones. There are a few remaining Monitor objects, those are going to be dropped by the next commit.

2011-05-08Introduce -machine command option.Anthony PERARD
This option gives the ability to switch one "accelerator" like kvm, xen or the default one tcg. We can specify more than one accelerator by separate them by a colon. QEMU will try each one and use the first whose works. So, ./qemu -machine accel=xen:kvm:tcg which would try Xen support first, then KVM and finally TCG if none of the other works. By default, QEMU will use TCG. But we can specify another default in the global configuration file.
