qemu docs says
- "slots=$N" should be equal to or larger than the total amount of
normal RAM devices and vNVDIMM devices, e.g. $N should be >= 2 here.
Do we need to specify additional ram slots when adding nvdimm? It looks like the guest only has one slot currently:

qemu docs says
"share=off", then guest writes won't be applied to the backend
file and thus will be invisible to other guests.
Does it mean all guest modification to rootfs will be lost?

"EnableNvdimm" needs to be added to BootConfig. otherwise the PR breaks cases with the older qemus. |
