For some device models, the guest can prevent unplug. Some users need a
way to forcibly revoke device model access to the block backend then, so
the underlying images can be safely used for something else.
drive_del lets you do that. Unfortunately, it conflates revoking access
with destroying the backend.
Commit 9063f81 made drive_del immediately destroy the root BDS. Nice:
the device name becomes available for reuse immediately. Not so nice:
the device model's pointer to the root BDS dangles, and we're prone to
crash when the memory gets reused.
Commit d22b2f4 fixed that by hiding the root BDS instead of destroying
it. Destruction only happens on unplug. "Hiding" means removing it
from bdrv_states and graph_bdrv_states; see bdrv_make_anon().
This "destroy on revoke" is a misfeature we don't want to carry
forward to blockdev-add, just like "destroy on unplug" (commit
2d246f0). So make drive_del fail on anything added with blockdev-add.
We'll add separate QMP commands to revoke device model access and to
destroy backends.

BLOCK_IO_ERROR events are logged by libvirt, which helps with

this string is a debugging aid for humans, meaning that it

Commit 3718d8ab65 ("block: Replace in_use
with operation blocker") broke the error path because it consumed
local_err instead of propagating it.
The caller has no way to know that the function failed. This caused
virtio-blk to start "successfully" even though there was a fatal
dataplane error.
Steps to reproduce:
$ qemu-system-x86_64 -enable-kvm -object iothread,id=iothread0 \
-drive if=none,id=drive0,file=a.img \
(qemu) drive_mirror drive0 /tmp/foo.img
(qemu) device_add virtio-blk-pci,iothread=iothread0,drive=drive0
Expected result:
Since the mirror block job is using drive0 it is not possible to start
virtio-blk data-plane.
device_add fails and the PCI adapter is not added.
Actual result:
device_add completes and the PCI adapter is added.

This patch avoids setting an irq while loading the state of the ISA bridge.
Because the i8259 has not been deserialized yet, raising an interrupt
could bring the system out-of-sync with the migration source. For example,
the migration source could have masked the interrupt in the i8259. On the
destination, the i8259 device model would not know that yet and would
trigger an interrupt in the CPU.
This patch eliminates setting the irq and just restores the calculated
state fields in post_load function. Interrupt state will be deserialized
separately through the IRR field of the i8259.

This is the next step for decoupling block accounting functions from
BlockDriverState.
In a future commit the BlockAcctStats structure will be moved from
BlockDriverState to the device models structures.
Note that bdrv_get_stats was introduced so device models can retrieve the
BlockAcctStats structure of a BlockDriverState without being aware of it's
layout.
This function should go away when BlockAcctStats will be embedded in the device
models structures.

The plan is to add new accounting metrics (latency, invalid requests, failed
requests, queue depth) and block.c is overpopulated so it will be better to work
in a separate module.
Moreover the long term plan is to have statistics in each of the BDS of the graph
for metrology purpose; this means that the device model statistics must move from
the topmost BDS to the device model.
So we need to decouple the statistic code from BlockDriverState.
This is another argument for the extraction of the code in a separate module.

Management software, such as RHEV's vdsm, want to be able to allocate
disk space on demand. The basic use case is to start a VM with a small
disk and then the disk is enlarged when QEMU hits a ENOSPC condition.
To this end, the management software has to be notified when QEMU
encounters ENOSPC. The solution implemented by this commit is simple:
it extends the BLOCK_IO_ERROR with a 'nospace' key, which is true
when QEMU is stopped due to ENOSPC.
Note that support for querying this event is already present in
query-block by means of the 'io-status' key. Also, the new 'nospace'
BLOCK_IO_ERROR field shares the same semantics with 'io-status',
which basically means that werror= has to be set to either
'stop' or 'enospc' to enable 'nospace'.
Finally, this commit also updates the 'io-status' key doc in the
schema with a list of supported device models.

caused by:

Note that in fixing it for compatibility with older QEMUs, it breaks
compatibility with existing QEMU 2.1's on older machine types.
The status before this patch was (if it used an XHCI adapter):
machine type | source qemu
any pre-2.1 - FAIL
any 2.1... - PASS
With this patch:

This fixes an issue with module build system. block/iscsi.so is
currently broken:
$ ~/build/last/qemu-img
Failed to open module: /home/fam/build/master/block-iscsi.so:
undefined symbol: qmp_query_uuid
qemu-img: Not enough arguments
Try 'qemu-img --help' for more information
To fix this, we should (at least) let qemu-img link qmp_query_uuid from
libqemustub.a. (There are a few other symbols missing, as well.)
This patch changes the linking rules to:
1) Build ".mo" with "ld -r -o $@ $^" for each ".so", and later build .so
with it.
2) Always build all the .mo before linking the executables. This is
achieved by adding those .mo files to the executables' "-y"
variables.
3) When linking an executable, those .mo files in its "-y" variables are
filtered out, and replaced by one or more -Wl,-u,$symbol flags. This
is done in the added macro "process-archive-undefs".
These "-Wl,-u,$symbol" flags will force ld to pull in the function
definition from the archives when linking.
Note that the .mo objects, that are actually meant to be linked in
the executables, are already expanded in unnest-vars, before the
linking command. So we are safe to simply filter out .mo for the
purpose of pulling undefined symbols.
process-archive-undefs works as this: For each ".mo", find all the
undefined symbols in it, filter ones that are defined in the
archives. For each of these symbols, generate a "-Wl,-u,$symbol" in
the link command, and put them before archive names in the command
line.

dtc fails on a recent QEMU snapshot:
ERROR (name_properties): "name" property in /hypervisor#1 is incorrect ("hypervisor" instead of base node name)
Looking at the device tree we have a hypervisor property:
# lsprop hypervisor
hypervisor "kvm"
But we also have a hypervisor node, with a name that doesn't match:
# lsprop hypervisor#1/
name "hypervisor"
compatible "linux,kvm"

Commit c08ce91d309c (spapr: add uuid/host details to device tree)
looks to have collided with an earlier patch. Remove the hypervisor
property.

We messed up the ordering in our default configs for PPC. The top entries
are generic entries, then come sections that indicate that features are only
in because of a special feature (such as PReP).
Fix the ordering again and while at it add eTSEC support to the ppc64 target
so that we can spawn eTSEC adapters with qemu-system-ppc64.

On sPAPR, virtio devices are connected to the PCI bus and use MSI-X.
Commit cc943c36fa has modified MSI-X
so that writes are made using the bus master address space and follow
the IOMMU path.
Unfortunately, the IOMMU address space address space does not have an
MSI window: the notification is silently dropped in unassigned_mem_write
instead of reaching the guest... The most visible effect is that all
virtio devices are non-functional on sPAPR since then. :(
This patch does the following:
1) map the MSI window into the IOMMU address space for each PHB
- since each PHB instantiates its own IOMMU address space, we
can safely map the window at a fixed address (SPAPR_PCI_MSI_WINDOW)
- no real need to keep the MSI window setup in a separate function,
the spapr_pci_msi_init() code moves to spapr_phb_realize().
2) kill the global MSI window as it is not needed in the end
