After backup update my zpools will not start

After backup Beta  update, my zpools will not start I get the following error

internal error: guest failed to start: Failure in libvirt_lxc startup: cannot find init path '/sbin/init' relative to container root: No such file or directory

This issue happened at the worst time ever I was demoing a project this weekend to a client.

so I have been at this for days around the clock I can't get anything to start it all started when I was a test user for the backup feature.
