I tried on tencent cloud server. Here are my operations: 1.edit /boot/grub/grub ,add memmap=16G!8G err1

2.sudo mkdir /mnt/ramdisk 3.sudo modprobe nova 4.sudo mount -t NOVA -o init /dev/pmem0 /mnt/ramdisk But it's wrong. err2

err3

Does anyone know how to solve this problem?

I am still suspecting this is a VM issue. The metadata of physical inode on pmem does not match the vnode. For example, inode number for root inode should be 1 but read as 0.

Still, I am suggesting trying on bare-metal machine first.
