Hi everyone,
Sheepdog is a distributed storage system for KVM/QEMU. It provides
highly available block level storage volumes to VMs like Amazon EBS.
Sheepdog supports advanced volume management features such as snapshot,
cloning, and thin provisioning. Sheepdog runs on several tens or hundreds

Sorry for a bit off topic. But, my special NBD server can do this

I saw MSR EFER and MSR STAR were saved to vmstate on target-x86_64 only.But
MSR EFER and MSR STAR can be accessed on target-i386,so should MSR EFER and
MSR STAR be saved to vmstate on target-i386 too?

cirrus_post_load() will be executed twice when loading vm states and then the
wrong physical memory will be registered. This issue may lead to crash qemu.

Currently, the msrs involved in setting up pvclock are not saved over
migration and/or save/restore. This patch puts their value in special
fields in our CPUState, and deal with them using vmstate.
kvm also has to account for it, by including them in the msr list
for the ioctls.

It would be much better to add a detectable string her
qemu_savevm_state will call all registered components with 3 phases: START,
PART, END. Only the PART phase is iterative.
In case of storage live migration we have lot more data to copy then memory
and usually the dirty rate is much less then memory dirty rate. I thought
about adding an iterative p

When using Linux AIO raw still falls back to POSIX AIO sometimes, so we should

Not initializing it happens to work if POSIX AIO is used by another drive, or

This patch adds generic serial ports over the virtio serial bus.
These ports have a few more options that are not relevant for
virtio console ports: the ability to cache buffers that are
received for a port while it's disconnected, setting of limits
to the bytes that are cached so as to prevent OOM
This patch migrates virtio-console to the qdev infrastructure and
creates a new virtio-serial bus on which multiple ports are exposed as
devices. The bulk of the code now resides in a new file with
virtio-console.c being just a simple qdev device.
This interface enables spawning of multiple virtio
