I got it to work using a 2 CPU, 4 GB RAM setup. Tried 4 CPU / 2 GB with scylla_cpuset_setup --smp 1, which should make scylla use only one CPU thread / shard -- did not work for me. Neither did 2 CPU / 1 GB.

I suggest simply increasing your specs a bit. I bought one VM for about $10 with 100 GB SSD+HDD -- so it's not that expensive.

How many cpus do you have in the machine? lscpu

I'm guessing 4 cpus since the error is: Only 476 MiB per shard; this is below the recommended minimum of 1 GiB/shard; terminating.Configure more memory (--memory option) or decrease shard count (--smp option)

Go to /etc/scylla.d/cpuset.conf and add change to the CPUSET="--smp 1" OR (if you are just testing on a dev environment enable developement mode inside /etc/scylla.d/dev-mode.conf.
