[PATCH v3 2/4] qcow2: add configurations for zoned format extension

To configure the zoned format feature on the qcow2 driver, it requires following arguments: the device size, zoned profile, zone model, zone size, zone capacity, number of conventional zones, limits on zone resources (max append sectors, max open zones, and max_active_zones). To create a qcow2 fil

[PATCH v3 0/4] Add full zoned storage emulation to qcow2 driver

This patch series add a new extension - zoned format - to the qcow2 driver thereby allowing full zoned storage emulation on the qcow2 img file. Users can attach such a qcow2 file to the guest as a zoned device. To create a qcow2 file with zoned format, use command like this: $ qemu-img create -f q

[PATCH v3 3/4] qcow2: add zoned emulation capability

[PATCH 4/6] vfio/migration: Change vfio_mig_active() semantics

vfio_mig_active() is used by migration_populate_vfio_info() to populate VFIO migration info when it is active. Currently, VFIO migration is considered active if there are VFIO devices and none of them has a migration blocker. Change that and consider VFIO migration to be active if there is a VFIO

[PATCH 3/6] vfio/migration: Add vfio_migratable_devices_num()

[PATCH 6/6] vfio/migration: Block VFIO migration with background snapshot

Background snapshot allows creating a snapshot of the VM while it's running and keeping it small by not including dirty RAM pages. The way it works is by first stopping the VM, saving the non-iterable devices' state and then starting the VM and saving the RAM while write protecting it with UFFD. T

[PATCH v8 02/12] Add virtio-sound-pci device

This patch adds a PCI wrapper device for the virtio-sound device. It is necessary to instantiate a virtio-snd device in a guest. All sound logic will be added to the virtio-snd device in the following commits. To add this device with a guest, you'll need a >=5.13 kernel compiled with CONFIG_SND_VI
