events - it just uses all the time for vCPU thread. Therefore main loop

In v4.2.0-246-ged9e923c3c the SMM property was moved from PC
machine class to x86 machine class. Makes sense, but the change
was too aggressive: in target/i386/kvm.c:kvm_arch_init() it
altered check which sets SMRAM if given machine has SMM enabled.
The line that detects whether given machine object is class of
PC_MACHINE was removed from the check. This makes qemu try to
enable SMRAM for all machine types, which is not what we want.

Hi,
With external processes or helpers participating to the VM support, it
becomes necessary to handle their migration. Various options exist to
transfer their state:
1) as the VM memory, RAM or devices (we could say that's how
vhost-user devices can be handled today, they are expected to
restore from ring state)
2) other "vmstate" (as with TPM emulator state blobs)
3) left to be handled by management layer
1) is not practical, since an external processes may legitimatelly
need arbitrary state date to back a device or a service, or may not
even have an associated device.
2) needs ad-hoc code for each helper, but is simple and working
3) is complicated for management layer, QEMU has the migration timing
The proposed "dbus-vmstate" object will connect to a given D-Bus
address, and save/load from org.qemu.VMState1 owners on migration.
Thus helpers can easily have their state migrated with QEMU, without
implementing ad-hoc support (such as done for TPM emulation)
D-Bus is ubiquitous on Linux (it is systemd IPC), and can be made to
work on various other OSes. There are several implementations and good
bindings for various languages. (the tests/dbus-vmstate-test.c is a
good example of how simple the implementation of services can be, even
in C)
dbus-vmstate is put into use by the libvirt series "[PATCH 00/23] Use
a slirp helper process".

Merge remote-tracking branch 'remotes/elmarco/tags/dbus-vmstate7-pull-request' into staging
Add dbus-vmstate
Hi,
With external processes or helpers participating to the VM support, it
becomes necessary to handle their migration. Various options exist to
transfer their state:
1) as the VM memory, RAM or devices (we could say that's how
vhost-user devices can be handled today, they are expected to
restore from ring state)
2) other "vmstate" (as with TPM emulator state blobs)
3) left to be handled by management layer
1) is not practical, since an external processes may legitimatelly
need arbitrary state date to back a device or a service, or may not
even have an associated device.
2) needs ad-hoc code for each helper, but is simple and working
3) is complicated for management layer, QEMU has the migration timing
The proposed "dbus-vmstate" object will connect to a given D-Bus
address, and save/load from org.qemu.VMState1 owners on migration.
Thus helpers can easily have their state migrated with QEMU, without
implementing ad-hoc support (such as done for TPM emulation)
D-Bus is ubiquitous on Linux (it is systemd IPC), and can be made to
work on various other OSes. There are several implementations and good
bindings for various languages. (the tests/dbus-vmstate-test.c is a
good example of how simple the implementation of services can be, even
in C)
dbus-vmstate is put into use by the libvirt series "[PATCH 00/23] Use
a slirp helper process".

Hi,
The following patches have been extracted from the "[PATCH v6 00/25]
monitor: add asynchronous command type", as they are
reviewable/mergeable independantly.
They introduce some internal API changes, and fix
qemu_open()/qemu_close()/unlink() misusages which should be quite
harmless.

When dropping backup-top, we need to drain the node before freeing the
BlockCopyState. Otherwise, requests may still be in flight and then the
assertion in shres_destroy() will fail.

QEMU currently supports writing compressed data of the size equal to
one cluster. This patch allows writing QCOW2 compressed data that
exceed one cluster. Now, we split buffered data into separate clusters
and write them compressed using the block/aio_task API.
