Replacing existing Centos 7 KVM hosts with Ubuntu

Hello all,

we are planning to replace all our CENTOS 7 KVM hosts with UBUNTU and keeping the same IPs, hostnames, cloudstack agent certs and settings.

When we try to connect a host back to the management server we get.

java.lang.IllegalArgumentException: Can't add host: 10.60.11.13 with hostOS: Ubuntu into a cluster,in which there are CentOS hosts added.

Any ideas?

 Can't add host: 10.60.11.13 with hostOS: Ubuntu into a cluster,in which
there are CentOS hosts added.

You have to have another cluster, for Ubuntu
if you read the manual, it says hosts need to be of the same OS, CPU
architecture etc...
you can't even mix e.g. RHEL and CentOS in the same cluster.

Best,
