run_on_cpu API does not yet support any way to pass over an error message
to above. Add a new run_on_cpu_func2 hook to grant possibility of that.
Note that this only changes the cpus-common core, no API is yet introduced
for v2 of the run_on_cpu_func function.

It allows accel->synchronize_post_init() hook to return an error upwards.
Add a new cpu_synchronize_post_init_full() for it, then let the existing
cpu_synchronize_post_init() to call it with errp==NULL.

Allow cpu_synchronize_all_post_init() to fail with an errp when it's set.
Modify both precopy and postcopy to try to detect such error.

This series teaches QEMU to detect errors when e.g. putting registers from
QEMU to KVM, and fail migrations properly.
For the rational of this series and why it was posted, please refer to the

This version of run_on_cpu() allows to take an Error** to detect errors.

Hi :
I am trying to write a new ACPI/smbios test framework that uses bios
bits (https://biosbits.org/ ).
This test will effectively:
(a) use a pre-built bits software zip file kept somewhere (where to
keep is TBD).
(b) unzip it.
(c) add a python based acpi and smbios test script to the unzipped
bit
oops, Phil's redhat email bounced!

I think the option should be boolean since it doesn't look like we're
going to need to tune the number very much.
It all boils down to "does the OS affirmatively support unaccepted
memory?" as in, we have no way to negotiate it, but force unaccepted
memory on.

Thanks everyone for your comments. This is a v3 patch that addresses all
suggestions (moving write_enable to decode_new_cmd).
I am waiting on some feedback from Dan's (dz4l...@gmail.com) patch
regarding adding a STATE_STANDBY state.
Currently, all tests are passing
