Snap install lxd failure

snapd

`snap install lxd
    error: cannot perform the following tasks:
    - Run install hook of "lxd" snap if present (run hook "install": cannot create cgroup hierarchy /sys/fs/cgroup/freezer/snap.lxd: Operation not permitted)`

When attempting to snap install lxd inside lxc container. Any ideas? I’m really blocked by this error. I looked at all of the previously proposed solutions, but none of them worked for me.

What’s snap version inside the container and outside the container?

Outside the container:
snap 2.45.3.1-1.el7
snapd 2.45.3.1-1.el7
series 16
centos 7
kernel 3.10.0-1127.19.1.el7.x86_64

Inside the container:
snap 2.47
snapd 2.47
series 16
ubuntu 18.04
kernel 3.10.0-1127.19.1.el7.x86_64

Is this a LXD container or the old-school lxc one?

Just for the record, can you also check that no SELinux denials are logged? Running ausearch -m AVC should provide the relevant information.

lxc exec daas-admin -- /bin/bash -c "ausearch -m"

/bin/bash: ausearch: command not found

This is the lxc container that is giving me issues.

The host is clearly RHEL/CentOS 7. Do you see any SELinux denials getting logged there?
