My virtual machine is Ubuntu20.04LTS, using kernel 5.4.225, device /dev/pmem0 is a device on the server, it has been virtualized, both /dev/pmem0 and kernel support DAX, However, when I run the mount -t NOVA -o init,dax,data_cow /dev/pmem0/mnt /data command, an error is displayed, as shown in the following figure. How can I solve it? here is dmesg novafail here is my /dev/pmem0 pmem0 I'll be pretty grateful for your help
