Now that virtio-scsi-pci and virtio-blk-pci map 1 virtqueue per vCPU,
a serious slow down may be observed on setups with a big enough number
of vCPUs.
Exemple with a pseries guest on a bi-POWER9 socket system (128 HW threads):
1 0m20.922s 0m21.346s
2 0m21.230s
Multiqueue devices such as virtio-scsi or virtio-blk, all open-code the
same pattern to setup/tear down host notifiers of the request virtqueues.
Consolidate the pattern in a new virtio_bus_set_host_notifiers() API.
Since virtio-scsi and virtio-blk both fallback to userspace if host
notifiers can't
Each addition or deletion of an eventfd happens in its own MR
transaction. This doesn't scale well with multiqueue devices
that do 1:1 queue:vCPU mapping (e.g. virtio-scsi-pci or
virtio-blk-pci) : these devices typically create at least one
eventfd per queue and memory_region_transaction_commit(),
This allows the virtio-scsi-pci device to batch additions and deletions
of host notifiers. This significantly improves boot time of VMs with a
high number of vCPUs, e.g. from 6m13.969s down to 1m4.268s for a pseries
machine with 384 vCPUs.

Introduce VirtioBusClass methods to begin and commit a transaction

by virtio-pci to batch addition and deletion of ioeventfds for multiqueue

Implement the ioeventfd_assign_begin() and ioeventfd_assign_commit()

Qemu crashes on shutdown if the chardev used by vhost-user-blk has been

This happens with char-socket chardev operating in the listening mode (server).

Hi,
When running qemu-system-ppc with Mac OS guest, the guest crashes when
using a tap network connection. Openvpn 2.4.9-I601-win10 is installed
with TAP-Windows 9.24.2. A tap connection called TapQemu is bridged
with the default ethernet connection. It gets activated when I start
qemu.

Document how multicore machines appear to GDB when debugged
via the debug stub. This is particularly non-intuitive for
the "multiple heterogenous clusters" case, but unfortunately
as far as I know there is no way with the remote protocol
for the stub to tell gdb "I have 2 inferiors, please connect
The way gdb and our gdbstub handle multicore and multicluster
machines is not very obvious. This patchset adds some documentation
of how to do it. In particular it gives the necessary runes
for how to get gdb to work with machines which have multiple
clusters of heterogenous CPUs (that's the sifiv

This series adds a few usability improvements to qemu-iotests, in
particular:
- arguments can be passed to Python unittests scripts, for example
to run only a subset of the test cases (patches 1-2)
- it is possible to do "./check -- ../../../tests/qemu
