Services don't start in lxc container after host update

I just upgraded my proxmox host , and now my first and most important container will not run any of it’s startup services, including processing fstab (have a ramdisk defined in it) .
My LXC container is running Ubuntu 16 LTS, with virtualmin. The container starts, and networking is working, but no services such as apache, webmin, even sshd are started. I have to enter the container from the host and manually start these services. cron doesn’t start and It also doesn’t even process my fstab which defines a ramdisk mount. Also cannot display the console from the proxmox web interface.

All my other lxc containers are working fine, but my first one ct 100, is having these issues.
How can I fix this?
