* qapi: Convert migrateLuiz Capitulino2012-03-151-1/+1
| | | | | | | | | | | | | | | | | | | | | | | | | The migrate command is one of those commands where HMP and QMP completely mix up together. This made the conversion to the QAPI (which separates the command into QMP and HMP parts) a bit difficult. The first important change to be noticed is that this commit completes the removal of the Monitor object from migration code, started by the previous commit. Another important and tricky change is about supporting the non-detached mode. That is, if the user doesn't pass '-d' the migrate command will lock the monitor and will only release it when migration is finished. To support this in the new HMP command (hmp_migrate()), it is necessary to create a timer which runs every second and checks if the migration is still active. If it is, the timer callback will re-schedule itself to run one second in the future. If the migration has already finished, the monitor lock is released and the user can use it normally. All these changes should be transparent to the user. Signed-off-by: Anthony Liguori <aliguori@us.ibm.com> Signed-off-by: Luiz Capitulino <lcapitulino@redhat.com>
* Purge migration of (almost) everything to do with monitorsLuiz Capitulino2012-03-151-5/+4
| | | | | | | | | | | | | | | | | 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.

* suspend: add infrastructureGerd Hoffmann2012-02-241-0/+9
| | | | | | | | | | | | | | | | | | | | | | | | | | This patch adds some infrastructure to handle suspend and resume to qemu. First there are two functions to switch state and second there is a suspend notifier: * qemu_system_suspend_request is supposed to be called when the guest asks for being be suspended, for example via ACPI. * qemu_system_wakeup_request is supposed to be called on events which should wake up the guest. * qemu_register_suspend_notifier can be used to register a notifier which will be called when the guest is suspended. Machine types and device models can hook in there to modify state if needed. * qemu_register_wakeup_notifier can be used to register a notifier which will be called when the guest is woken up. Machine types and device models can hook in there to modify state if needed. * qemu_system_wakeup_enable can be used to enable/disable wakeup events.

* kvm: x86: Establish IRQ0 override controlJan Kiszka2012-01-191-1/+0

* Add generic drive hotpluggingAlexander Graf2012-01-041-1/+5
| | | | | | | | | | | | | | | | | | | | | | | The monitor command for hotplugging is in i386 specific code. This is just plain wrong, as S390 just learned how to do hotplugging too and needs to get drives for that. So let's add a generic copy to generic code that handles drive_add in a way that doesn't have pci dependencies. All pci specific code can then be handled in a pci specific function.

* runstate: Allow user to migrate twiceLuiz Capitulino2011-10-191-0/+1
| | | | | | | | | | | | | It should be a matter of allowing the transition POSTMIGRATE -> FINISH_MIGRATE, but it turns out that the VM won't do the transition the second time because it's already stopped. So this commit also adds vm_stop_force_state() which performs the transition even if the VM is already stopped. While there also allow other states to migrate.

* RunState: Rename enum values as generated by the QAPILuiz Capitulino2011-10-041-14/+14
| | | | | | | | | | | | | | | | | | | | | | | Next commit will convert the query-status command to use the RunState type as generated by the QAPI. In order to "transparently" replace the current enum by the QAPI one, we have to make some changes to some enum values. As the changes are simple renames, I'll do them in one shot. The changes are: - Rename the prefix from RSTATE_ to RUN_STATE_ - RUN_STATE_SAVEVM to RUN_STATE_SAVE_VM - RUN_STATE_IN_MIGRATE to RUN_STATE_INMIGRATE - RUN_STATE_PANICKED to RUN_STATE_INTERNAL_ERROR - RUN_STATE_POST_MIGRATE to RUN_STATE_POSTMIGRATE - RUN_STATE_PRE_LAUNCH to RUN_STATE_PRELAUNCH - RUN_STATE_PRE_MIGRATE to RUN_STATE_PREMIGRATE - RUN_STATE_RESTORE to RUN_STATE_RESTORE_VM - RUN_STATE_PRE_MIGRATE to RUN_STATE_FINISH_MIGRATE Signed-off-by: Luiz Capitulino <lcapitulino@redhat.com>

* runstate_set(): Check for valid transitionsLuiz Capitulino2011-09-151-0/+1
| | | | | | | | | | | | This commit could have been folded with the previous one, however doing it separately will allow for easy bisect and revert if needed.

* RunState: Add additional statesLuiz Capitulino2011-09-151-1/+7
| | | | | | | | | | | | Currently, only vm_start() and vm_stop() change the VM state. That's, the state is only changed when starting or stopping the VM. This commit adds the runstate_set() function, which makes it possible to also do state transitions when the VM is stopped or running. Additional states are also added and the current state is stored.

* Replace the VMSTOP macros with a proper state typeLuiz Capitulino2011-09-151-14/+19
| | | | | | | | | | | | | | | Today, when notifying a VM state change with vm_state_notify(), we pass a VMSTOP macro as the 'reason' argument. This is not ideal because the VMSTOP macros tell why qemu stopped and not exactly what the current VM state is. One example to demonstrate this problem is that vm_start() calls vm_state_notify() with reason=0, which turns out to be VMSTOP_USER. This commit fixes that by replacing the VMSTOP macros with a proper state type called RunState. Signed-off-by: Luiz Capitulino <lcapitulino@redhat.com>

* showing a splash picture when startwayne2011-07-291-0/+3
| | | | | | | | | | | | | | | Added options to let qemu transfer two configuration files to bios: "bootsplash.bmp" and "etc/boot-menu-wait", which could be specified by command -boot splash=P,splash-time=T P is jpg/bmp file name or an absolute path, T have a max value of 0xffff, unit is ms. With these two options, if user invoke qemu with menu=on option, then a splash picture would be showed in a given time. For example: qemu -boot menu=on,splash=/root/boot.bmp,splash-time=5000 would make boot.bmp shown as a brand with 5 seconds in the booting up process. This feature need the new seabios's support, which could be got from git. Signed-off-by: Wayne Xia <xiawenc@linux.vnet.ibm.com> Signed-off-by: Anthony Liguori <aliguori@us.ibm.com>

* savevm: Fix no_migrateAlex Williamson2011-01-171-0/+1
| | | | | | | | | | | | | | | | | | | The no_migrate save state flag is currently only checked in the last phase of migration. This means that we potentially waste a lot of time and bandwidth with the live state handlers before we ever check the no_migrate flags. The error message printed when we catch a non-migratable device doesn't get printed for a detached migration. And, no_migrate does nothing to prevent an incoming migration to a target that includes a non-migratable device. This attempts to fix all of these. One notable difference in behavior is that an outgoing migration now checks for non-migratable devices before ever connecting to the target system. This means the target will remain listening rather than exit from failure. Signed-off-by: Alex Williamson <alex.williamson@redhat.com> Signed-off-by: Michael S. Tsirkin <mst@redhat.com>

The qxl device is the bridge between the guest and the spice server (aka libspice-server). The spice server will send the rendering commands to the spice client, which will actually render them. The spice server is also able to render locally, which is done in case the guest wants read something from video memory. Local rendering is also used to support display over vnc and sdl. qxl is activated using "-vga qxl". qxl supports multihead, additional cards can be added via '-device qxl".
