[PATCH 0/5] qemu: Introduce nvme disk emulation support

From: hongleiwang <honglei.wang(a)smartx.com&gt; 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 and nvme-ns disk bus type: A disk with nvme as bus is represented as nvme disk that contains only one nvme namespace. 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='nvmea' bus='nvme'/> <serial>nvme-serial-value</serial> </disk> ... </devices> 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> ray (5): qemu: Add support for NVMe disk bus type qemu: Add support for NVMe namespace disk bus type qemu_capabilities: Add support for NVMe
