I don't think anything would show up in the mounts on the host itself.
The problem is probably with some of the hardenings enabled in the
corosync service, for example:

https://salsa.debian.org/ha-team/corosync/-/blob/debian/master/debian/patches/Enable-PrivateTmp-in-the-systemd-service-files.patch

I seem to remember having this problem on my machine too were apparmor
was blocking the mount, and the solution was to add these to the config
of all containers:

# Apparmor enable
lxc.apparmor.profile = generated
lxc.apparmor.allow_nesting = 1
