Nova Compute Service fail to start

I deployed a simplex of version 2018.10.But there is an error in nova compute service. This is part of the error log: No such file or directory: '/dev/cpuset/floating/node0/cpuset.cpus'.

This appears to be a duplicate of https://bugs.launchpad.net/starlingx/+bug/1830595
I expect the intention was not to open two bugs reporting the same issue.
