Well, it's way too big because we have a bad worst-case:
a TB with lots of insns that generate a lot of TCG ops.
That pretty much never happens but you can't rule it out

I started down the path toward using this guard page to trigger
a restart of the translation for a given TB, but got hung up on
the win32 implementation of the "signal handler".
Nevertheless, just having the page without doing anything more
than crashing if it gets touched might still be useful.

Hello,
Based on my pending qom-next pull, this series continues Eduardo's machine
cleanups.
Having eliminated QEMUMachine and qemu_machine_register(), this series
eliminates
machine_init() and MODULE_INIT_MACHINE.
As a side effect a few non-machine callers had to be updated, mostly for
QemuOpt
The TypeInfos are being generated statically and the name is a constant.

Replace error_report() and use tracing instead. It's not an error to get
a connection or a disconnection, so silence this and trace it instead.

Add qemu_memfd_alloc/free() helpers.
The function helps to allocate and seal a memfd, and implements an
open/unlink/mmap fallback for system that do not support memfd.

If the backend is of type VHOST_BACKEND_TYPE_USER, allocate
shareable memory. Next patch will only allocate when the backend
has the required feature.
Note: vhost_log_get() can use a global "vhost_log" that can be shared by
several vhost devices. We may want instead a com

Implement memfd_create() fallback if not available in system libc.
memfd_create() is still not included in glibc today, atlhough it's been
available since Linux 3.17 in Oct 2014.

Hi,
The following series implement shareable log for vhost-user to support
memory tracking during live migration. On qemu-side, the solution is
fairly straightfoward since vhost already supports the dirty log, only
vhost-user couldn't access the log memory until then.

With 9p mounted, we don't support qemu migration. We have
migration blocker added in v9fs_attach.

That's doable, I'll add it after the feature protocol is added (not in
this commit)
