When KVM device "kvm-arm-gicv3" or "arm-its-kvm" is used, we have to

The library directory can change depending on the multilib setup of the host.
It would be even better to detect it in configure with the same algorithm

Currently VFIO migration doesn't implement some kind of intermediate
quiescent state in which P2P DMAs are quiesced before stopping or
running the device. This can cause problems in multi-device migration
where the devices are doing P2P DMAs, since the devices are not stopped
together at the same t
Currently, if IOMMU of a VFIO container doesn't support dirty page
tracking, migration is blocked. This is because a DMA-able VFIO device
can dirty RAM pages without updating QEMU about it, thus breaking the
migration.
However, this doesn't mean that migration can't be done at all.
In such case, a
Add new function qemu_file_get_to_fd() that allows reading data from
QEMUFile and writing it straight into a given fd.
This will be used later in VFIO migration code.

migration protocol v1. This will allow the two protocols to co-exist
when v2 protocol is added, until v1 is removed. No functional changes

it will make it easier to add the v2 protocol implementation later.

During pre-copy phase of migration vfio_save_pending() is called
repeatedly and queries the VFIO device for its pending data size.
As long as pending RAM size is over the threshold, migration can't
converge and be completed. Therefore, during this time there is no
point in querying the VFIO device
Now that VFIO migration protocol v2 has been implemented and v1 protocol
has been removed, update the documentation according to v2 protocol.

Hi Stefan,
For true virtio-fs migration, we need to migrate the daemon’s (back
end’s) state somehow. I’m addressing you because you had a talk on this
topic at KVM Forum 2021. :)
As far as I understood your talk, the only standardized way to migrate a
vhost-user back end’s state is via dbus

books and drawers are already handled via the entries in
CpuInstanceProperties, so this sentence looks like a wrong leftover now?
I'd suggest talking about "dedication"
