The invalidation code introduced in commit 2360b works by inverting most bits
of env->msr to ensure that hreg_store_msr() will forcibly update the CPU env
state to reflect the new msr value post-migration. Unfortunately
hreg_store_msr() is called with alter_hv set to 0 which preserves the MSR_HVB

Currently, virtio code chooses to kill QEMU if the guest passes any invalid

guest user is writing a very long email), or possible denial of service in
a nested vm use case where virtio device is passed through.

The image field in BlockDeviceInfo is supposed to contain an ImageInfo
object. However that is being filled in by bdrv_query_info(), not by
bdrv_block_device_info(), which is where BlockDeviceInfo is actually
created.
Anyone calling bdrv_block_device_info() directly will get a null image
field. As

The image field in BlockDeviceInfo should never be null, however
bdrv_block_device_info() is not filling it in.
This makes the 'info block -n -v' command crash QEMU.
The proper solution is probably to move the relevant code from

dump-pc-mem command is added for checkpointing guest memory to
file. Only system RAM region is saved. This checkpoint is later used to
recover unchanged pages.

The reason to do this is that the virtio-net-device can't expose host
features to guest while using virtio-mmio. So the performance is low.
The virtio-*-pci, virtio-*-s390, and virtio-*-ccw already have the ability
to forward property accesses to the backend child, by calling

These are used for:
* live migration
* VM state save/load (eg via monitor 'savevm' and 'loadvm'
commands or command line -loadvm option).

Does loadvm create new virtual devices (dev.init(), dev.realize(), etc.)
for the vm to run onto and then load VMStateDescription?

loadvm itself does not, no. You have to start QEMU with the
exact same configuration and command line options, whi

It is reasonably common to want to create an object, set a
number of properties, register it in the hierarchy and then
mark it as complete (if a user creatable type). This requires
quite alot of error prone, verbose, boilerplate code to achieve.
The object_new_propv / object_new_proplist construct
The qemu_acl_init() function has long since stopped being able
to return NULL, since g_malloc will abort on OOM. As such the
checks for NULL were unreachable code.

Introduce a new crypto/ directory that will (eventually) contain
all the cryptographic related code. This initially defines a
wrapper for initializing gnutls and for computing hashes with
gnutls. The former ensures that gnutls is guaranteed to be
initialized exactly once in QEMU regardless of CLI a
The QEMU help for -object is essentially useless, just giving users
the generic syntax. Move it down into its own section and introduce
a nested table where each user creatable object can be documented.
The existing memory-backend-file, rng-random and rng-egd object
types are documented.
