buffer_find_nonzero_offset() is a hot function during live migration.
Now it use SSE2 instructions for optimization. For platform supports
AVX2 instructions, use AVX2 instructions for optimization can help
to improve the performance about 30% comparing to SSE2.
Zero page check can be faster with t
Detect if the compiler can support the ifun and avx2, if so, set
CONFIG_AVX2_OPT which will be used to turn on the avx2 instruction
optimization.

This patch adds support for qom-type-list command that supposed to list object
class properties. Will use this functionality further to implement x86_64 cpu
properties.
Additionally object_class_property_iterator_init function is implemented for
consistency.

Hi folks,
Could you enlighten me how to achieve proportional IO sharing by using cgroup,
instead of qemu's io-throttling?
My qemu config is like: -drive
file=$DISKFILe,if=none,format=qcow2,cache=none,aio=native -device
virtio-blk-pci...
Test command inside vm is like: dd if=/dev/vdc of=/dev/
Sorry for disturbing by reply, don't know why I'm not able to send a new

Hello!

Where do they say this? I remember that "we want to use KVM_EXIT_IO or
KVM_EXIT_MMIO for handling device I/O". In other words - we
should not introduce anything that requires any other mechanism (e. g.
hypercalls) to handle this. An

Hi Quan,
I'm currently testing and reviewing. I also have some colleagues doing the same
thing.
So far: I haven't had any issues with it - this seems to work quite nicely.
I will keep testing but I don't really expect any functional hiccups.
Best Regards,
Hagen
