using podman

[spippoli]

I'm trying to use podman on rhel, but I get the following error:

[arnardo@nominatim ~]$ sudo podman run -it \

Check your installation.

And yet if I get into the container I can see it's there

[arnardo@nominatim ~]$ sudo podman run -it \

What am I doing wrong?

popen failure: Cannot allocate memory

suggests that you're running out of memory.

I'm myself a podman user and haven't seen any problems yet.

That's strange, I'm trying to run the container on a clean machine with 64GB RAM.
Shouldn't podman be able to use the host resources unless explictly limited?
