In 99% cases, after QEMU migrates to dest host, it tries to detect the
target VM runstate using global_state_get_runstate().
There's one outlier so far which is Xen that won't send global state.
That's the major reason why global_state_received() check was always there
together with global_state_g
This patch proposes a flag to maintain disk activation status globally. It
mostly rewrites disk activation mgmt for QEMU, including COLO and QMP
command xen_save_devices_state.
Backgrounds

We have two problems on disk activations, one resolved, one not.
Problem 1: disk activation re

Postcopy never cared about late-block-active. However there's no mention
in the capability that it doesn't apply to postcopy.
Considering that we _assumed_ late activation is always good, do that too
for postcopy unconditionally, just like precopy. After this patch, we
should have unified the be
Migration capability 'late-block-active' controls when the block drives
will be activated. If enabled, block drives will only be activated until
VM starts, either src runstate was "live" (RUNNING, or SUSPENDED), or it'll
be postponed until qmp_cont().
Let's do this unconditionally. There's no ha
Src QEMU sets block_inactive=true very early before the invalidation takes
place. It means if something wrong happened during setting the flag but
before reaching qemu_savevm_state_complete_precopy_non_iterable() where it
did the invalidation work, it'll make block_inactive flag inconsistent.

As the comment says, the activation of disks is for the case where
migration has completed, rather than when QEMU is still during
migration (RUN_STATE_INMIGRATE).
Move the code over to reflect what the comment is describing.

This series extends our documentation with new pages to help developers
onboarding on QEMU. It focuses on providing a big picture of QEMU (to a
modest extend).
As such, it was written to be simple, short, easy to understand, and pointing to
more details. It provides another way to dive into detail

MacOS and Linux are straightforward, but Windows needs a bit more
