When a request R is absorbed by request M, it is appended to the
"mr_next" queue led by M, and is completed together with the completion
of M, in virtio_blk_rw_complete.
With error policy equals stop, if M has an I/O error, now R also gets
prepended to the per device DMA restart queue, which will

Second version of the patch, following all suggestions by Stefan.

Use cpu_get_phys_page_attrs_debug() when doing virtual-to-physical
conversions in debug related code, so that we can obtain the right
address space index and thus select the correct AddressSpace,

Since the PXB has no longer a built-in PCI bridge, the
ACPI will include IO/MEM ranges per device. Try to merge

The PXB host bridge provides a way to have multiple PCI hierarchies (PCI root
buses).
This series is porting the PXB device to Q35 machines by:
- removing the internal pci-bridge
- make the PXB bus PCIe for Q35, while it remains PCI for i440fx.
This approach works because the Root Complexes are

As part of porting the pxb device to Q35 remove the internal pci-2-pci
bridge. The only way to hot-pug devices on the extra PCI root buses
is by adding a pci-2-pci to the pxb before the firmware assign the
IO/mem resources.
Keep the internal bridge for existing machines.

This patch series adds support to QEMU's core exec/memory code for
CPUs which have more than one address space, and uses it for
ARM TrustZone. In particular, a TZ CPU will have two physical
address spaces (Secure and Non-secure), and the patchset allows a
board model to create these both separately
The taihu_cpld_writel() function had an obvious typo that meant that
if it was ever called it would go into an infinite recursion. Newer
versions of clang will detect and warn about this:
hw/ppc/ppc405_boards.c:481:1: warning: all paths through this function will
call itself [-Winfinite-recursio
to create snapshot for all loaded block drivers.
The patch also ensures proper locking.

fafcaf1 added a 'qemu-ga' install target on w32, which can be used
in place of the existing qemu-ga.exe target to also handle dealing
with other components such as DLLs for VSS/fsfreeze and generating
an MSI package if appropriate configure options are present.
As part of that, qemu-ga$(EXESUF) wa

to check that snapshot is available for all loaded block drivers. The
ability to switch to snapshot is verified separately using

State deletion can be performed on running VM which reduces VM downtime
This approach looks a bit more natural.

This patch enables migrating vcpu's TSC rate. If KVM on the destination
machine supports TSC scaling, guest programs will observe a consistent
TSC rate across the migration.
If TSC scaling is not supported on the destination machine, the
migration will not be aborted and QEMU on the destination wi

asserts, errors.
Anyway, I think that the construction like

EFI based VM with pflash storage for NVRAM could not be snapshoted as
libvirt configures storage as 'raw' and writable. OK, this is a libvirt
problem.
Another problem is that libvirt can not detect this failure at all
as it uses HMP for this operation. This create snapshot/delete snapshot
