hah, bingo, the default kernel package for VMs doesn't have nd_pmem or
nd_btt. I had to install linux-modules-extra-5.4.0-12-generic.
Now it works:
ubuntu@focal-nvdimm:~$ sudo ndctl create-namespace
{
"dev":"namespace1.0",
"mode":"fsdax",
"map":"dev",
"size":"1006.00 MiB (1054.87 MB)",
"uuid":"53defad5-c13c-4f3c-abbb-d9152db43c69",
"sector_size":512,
"align":2097152,
"blockdev":"pmem1"
}
Thanks a lot, Dan!
