[weizhouapache]

Description

This PR fixes #8597

note

• I cannot reproduce the same issue that host is "already in the database". (https://github.com/apache/cloudstack/issues/9034#issuecomment-2092819989)
• I was able to reproduce the issue that "Unable to add host" by renaming /usr/sbin/kvm-ok on ubuntu 22.04 host. when I changed the string in this PR, the issue is ignored.
