GitHub user shakibshalim74 created a discussion: CloudStack KVM Host Reinstallation – Reusing Hostname and IP
Hello CloudStack Community, We are currently running Apache CloudStack 4.19.3 with KVM hosts on Ubuntu 20.04. Before upgrading CloudStack to 4.22, we plan to upgrade the KVM hypervisors to Ubuntu 24.04 LTS. For example, we have a KVM host cshost10.xyz.com with IP 10.1.1.10. We plan to reinstall the OS with Ubuntu 24.04 and then reinstall/configure the CloudStack agent, libvirt, and required packages. Our question is: Can we safely reuse the same hostname and IP (cshost10.xyz.com / 10.1.1.10) after the fresh OS installation and reconnect it to the existing CloudStack host record, without modifying or manually changing the CloudStack database? Or is it recommended to use a new hostname/IP and add it as a new host? Any guidance or recommended best practices would be appreciated.
