For some pci device, even its PCI_INTERRUPT_PIN is not 0, it actually
doesn't support INTx mode, so its machine irq read from host sysfs is 0.
In that case, report PCI_INTERRUPT_PIN as 0 to guest and let passthrough
continue.

"-machine pc" will not work all architectures. Lets fall back to the
default machine by not specifying it.
In addition we also need to specify -no-shutdown on s390 as qemu will
exit otherwise.

Since root and downstream port have only one slot, device should be
connected to them using slot 0. QEMU doesn't have a check for that
and starts up when a non-zero slot is specified, though the device
is not seen in guest OS.
The change fixes that by adding a check in PCI device "attr" property

This series improves the QMP SHUTDOWN and RESET events by adding

This makes it possible to determine what the exact reason was for
a RESET or a SHUTDOWN. A management layer might need the specific reason

It is interesting to know whether the shutdown cause was 'quit' or
'reset', especially when using "--no-reboot". In that case, a management
layer can now determine if the guest wanted a reboot or shutdown, and
can act accordingly.
Changes the output of the reason in the iotests from 'host-qmp' to

At the time, the "drained section" doesn't protect Block Driver State
from the requests appearing in the vCPU threads.
This could lead to the data loss because of request coming to
an unexpected BDS.
For example, when a request comes to ide controller from the guest,
the controller creates a reque

Could you please write, what is the behavior change and why here?
Is it a bug, that FUA was not inherited before?

Given I've spent a fair amount of time around this code now I'm
putting myself forward as a maintainer. Also given that the code has
been extensively re-written and has testing and new incoming features
it's probably more than just Odd Fixes.

An update of:
v1: https://lists.gnu.org/archive/html/qemu-devel/2018-11/msg06222.html
We made the debugger module WinDbg (like GDB) for QEMU. This is the replacement
of the remote server in Windows kernel. Used for remote Windows kernel debugging
without debugging mode.
WinDbg is a multi
Header file from windbg's source code describing the main structures.

It is necessary to find address on the structure kdDebuggerDataBlock,
which is located somewhere at kernel .data section.
We can find it in structure defined in kernel:
typedef struct _DBGKD_DEBUG_DATA_HEADER
{
LIST_ENTRY64 List;
ULONG OwnerTag;
ULONG Size;
} DBGKD_DEBUG_DATA_HEADER, *
