This patch allows CPUs to be hotplugged to a running guest. The QEMU
option (maxcpus) can be used to define the total number of standby
and configured CPUs available at boot time, although it is not
necessary because you can hotplug standby CPUs after boot time. For
example, the
Hi all,
this is what our approach to CPU hotplug looks like.
With respect to Igor's CPU hotplug series, how should we proceed?
Should we change the interface to

Feedback regarding the non-API part is also highly welcome!

No. The idea was to make the loop cheaper when you had a qemu_notify_event()

immediately multiple times. When that happens, it is

This patch adds a ftrace tracing backend which sends trace event to
ftrace marker file. You can effectively compare qemu trace data and
kernel(especially, kvm.ko when using KVM) trace data.
The ftrace backend is restricted to Linux only.
To try out the ftrace backend:
$ ./configure --trace-backe
This patchset introduces a new tracing backend "ftrace".
Currently, QEMU tracing backends do not support userspace tracing with ftrace.
Collecting QEMU trace data and kernel trace data simultaniouly is useful for
latency analysis and debugging especially when using KVM.
With ftrace backend, you c

This if-else logic inhibits setting of the event status (ES) bits
when interrupts are enabled. This is incorrect. ES should be set
regardless on INTEN state. INTEN only inhibits the signalling of

Since qcow2 metadata is cached we need to flush the caches, not just the
underlying file. Use bdrv_flush(bs) instead of bdrv_flush(bs->file).
Also add the error return path when bdrv_flush() fails and move the
flush after checking for qcow2_alloc_clusters() failure so that

XBZRLE encoded migration introduced a MRU page cache
meachnism. Unfortunately, cached items where never freed in
case of a collision in the page cache on cache_insert().
This lead to out of memory conditions during XBZRLE migration

Current colon position in "waiting for telnet connection" message template
produces messages like:
QEMU waiting for connection on: telnet::127.0.0.1,server
After moving a colon to the right, we will get a correct messages like:

Obviously, hub does not support multiqueue tap. So this patch forbids creating
multiple queue tap when hub is used to prevent the crash when command line such
as "-net tap,queues=2" is used.

update_refcount() affects the refcount cache, it does not write to disk.
Therefore bdrv_flush(bs->file) does nothing. We need to flush the
refcount cache in order to write out the refcount updates!
While we're here also add error returns when qcow2_cache_flush() fails.

The nature of the kernel ABI for the get_robust_list and set_robust_list

virtio-blk registers a vmstate change handler. Unfortunately this
handler is not unregistered on unplug, leading to some random
crashes if the system is restarted, e.g. via virsh reboot.
Lets unregister the vmstate change handler if the device is removed.

Currently the spapr-vlan device does not supply a cleanup call for its
NetClientInfo structure. With current qemu versions, that leads to a SEGV

is_tcg_gen_code() checks the upper limit of TCG generated code range wrong, so
that TCG could get broken occasionally only when CONFIG_QEMU_LDST_OPTIMIZATION

Otherwise, live migration of the top layer will miss zero clusters and
let the backing file show through. This also matches what is done in qed.
QCOW2_CLUSTER_ZERO clusters are invalid in v2 image files. Check this
