Thanks Patrick, I found that this was accessible on host as /writable/system-data/var/lib/snapd/seed/cmdline.txt and updating it there worked (after reboot).

I was able to enable it by adding `cgroup_enable=memory cgroup_memory=1` to the kernel command line, but on Ubuntu I think the memory cgroup should be enabled by default shouldn't it? $ cat /proc/cgroups #subsys_name hierarchy num_cgroups enabled cpuset 2 1 1 cpu 4 100 1 cpuacct 4 100 1 blkio 5 100 1 memory 0 109 0 devices 6 100 1 freezer 9 4 1 net_cls 3 1 1 perf_event 10 1 1 net_prio 3 1 1 pids 8 107 1 rdma 7 1 1 I see this with Linux localhost 5.4.0-1043-raspi #47~18.04.1-Ubuntu SMP PREEMPT Mon Aug 23 14:39:46 UTC 2021 aarch64 aarch64 aarch64 GNU/Linux on Ubuntu Core 18, but folks have informed me that the same is true on Ubuntu Core 20 as well.
