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.

The user may already have paused the VM before starting the migration process. If s/he does that, then the state will be 'paused' when we finish the migration process. In that case we want to transition from 'paused' to 'postmigrate' as the latter is now the real reason why the VM is stopped. Signed-off-by: NLuiz Capitulino <lcapitulino@redhat.com>

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: NLuiz Capitulino <lcapitulino@redhat.com>

We have two states where issuing cont before system_reset can cause problems: RSTATE_SHUTDOWN (when -no-shutdown is used) and RSTATE_PANICKED (which only happens with kvm). This commit fixes that by doing the following when state is RSTATE_SHUTDOWN or RSTATE_PANICKED: 1. returning an error to the user/client if cont is issued 2. automatically transition to RSTATE_PAUSED during system_reset Signed-off-by: NLuiz Capitulino <lcapitulino@redhat.com>

Test against RSTATE_IN_MIGRATE instead. Please, note that the RSTATE_IN_MIGRATE state is only set when all the initial VM setup is done, while 'incoming_expected' was set right in the beginning when parsing command-line options.

This commit could have been folded with the previous one, however doing it separately will allow for easy bisect and revert if needed. Checking and testing all valid transitions wasn't trivial, chances are this will need broader testing to become more stable. This is a transition table as suggested by Lluís Vilanova.

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.

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: NLuiz Capitulino <lcapitulino@redhat.com>

Enabling the I/O thread by default seems like an important part of declaring 1.0. Besides allowing true SMP support with KVM, the I/O thread means that the TCG VCPU doesn't have to multiplex itself with the I/O dispatch routines which currently requires a (racey) signal based alarm system. I know there have been concerns about performance. I think so far the ones that have come up (virtio-net) are most likely due to secondary reasons like decreased batching. I think we ought to force enabling I/O thread early in 1.0 development and commit to resolving any lingering issues. Signed-off-by: NAnthony Liguori <aliguori@us.ibm.com>

This allows GSources to be used to register callback events in QEMU. This is useful as it allows us to take greater advantage of glib and also because it allows us to write code that is more easily testable outside of QEMU since we can make use of glib's main loop in unit tests. All new code should use glib's callback mechanisms for registering fd events which are very well documented at: http://developer.gnome.org/glib/stable/glib-The-Main-Event-Loop.html And: http://developer.gnome.org/gio/stable/Signed-off-by: NAnthony Liguori <aliguori@us.ibm.com> Signed-off-by: NAnthony Liguori <aliguori@us.ibm.com>

If we call select without a timeout, it's more efficient to keep the global mutex locked as we may otherwise just play ping pong with a vcpu thread contending for it.
