QEMU has supported nvme disk emulation for a long time,
see: https://qemu-project.gitlab.io/qemu/system/devices/nvme.html.
The following patches introduce nvme-ns disk bus type:
A disk with nvme-ns as bus is represented as an nvme namespace
and needs to be attached to an nvme controller. In XML, it can be
used like this:
<devices>
...
<disk type='file' device='disk'>
<driver name='qemu' type='raw'/>
<source file='/tmp/data.img'/>
<target dev='nvmensa' bus='nvme-ns'/>
<address type='drive' controller='0' bus='0'
target='0' unit='0'/>
</disk>
<controller type='nvme' index='0'>
<serial>nvme-controller-serial-value</serial>
<address type='pci' domain='0x0000' bus='0x00'
slot='0x05' function='0x0'/>
</controller>
...
</devices>

Compared to patch v1, this version removes the nvme bus type implementation
and keeps only the nvme controller + nvme-ns bus approach.
ray (5):
qemu: Add support for NVMe namespace disk bus type
qemu_capabilities: Add support for nvme-ns bus capabilities
schema: Add nvme controller and nvme-ns bus defination
tests: Add test case for nvme-ns device configuration
NEWS: Document qemu nvme disk emulation feature
