[libvirt] virtio pmem support in libvirt

[Pankaj Gupta]

Hi all,

Virtio-pmem support has been added to kernel[1] and qemu[2]
upstream. User document[3] has more details on how to use this 
new device.

We now need support in libvirt. Required support would be a subset
of features already implemented for emulated nvdimm. We will use
new virtio-pmem-pci device and don't require advance ACPI configurations. 

Can libvirt upstream community implement libvirt support for virtio pmem
to complete the entire stack.

Thank you in advance.

Best regards,
Pankaj
